I think the thing I dislike about Duolingo is it sort of catches the casual person into a trap by misleading them into thinking that by using this app they'll learn another language. It's not that it's a bad app, it's just that that's not going to happen. There's no one resource that will get you to even an intermediate level in a language. And the State Department's FSI estimates are unfortunately pretty accurate for hours to fluency [1].

For me to put a foundation for French down it was: Assimil for about 6 months (30 min/day), 30 minutes of daily comprehensible input, and Anki & Clozemaster for vocabulary (~15-20 min/day). Mixed in there was a couple months on Yabla doing listening comprehension, some grammar study from Bescherelle books, and some tutoring on iTalki. After about maybe 9-12 months I could listen to RFI's broadcast targeted to learners [2], but even then I still needed to go to the transcription a lot at the beginning.

To mislead people into thinking that doing some vocab study for 30 min a day in Duolingo is going to get them anything beyond the most basic grasp of a language is kinda not cool.

Both of my parents are teachers of a European language. They both have phd's in linguistics, and rate very highly with students (who basically adore them).

All of this context to say that not once has anyone using Duolingo been able to "test out" of the first ("101") class that they teach. Duolingo self-learners come in with a very unequal mix of vocabulary and... not much else. Unable to use declension properly [0], unaware of most rules around gender, verb tenses, etc.

I'm sure (and I should look it up) that there have been academic papers written on these quite different methods/approaches: gamified learning vs "academic" learning, immersion by moving to a country, etc.

But in my parents' experience of teaching (which spans ~40 yrs), Duolingo students pretty much all became disappointed in the app: these students thought that they had developed skills when it turns out they mostly got addicted to a game that overpromised useful learning over entertainment.

Imho, the ugly truth is that language learning as an adult is deeply hard and requires a tremendous amount of effort and "tricks" to keep yourself motivated. People who watch native media with subtitles, play with AI apps (such as the YC backed https://www.issen.com/ which is quite nice), take a mix of "classic" classes, spend time in a country where the language is spoken and force themselves into situations where they "have" to speak, etc. all do much better. But it's a ton of effort.

I'm currently holding a 1100 days of streak of Italian in Duolingo, so I think I am entitled to drop in my 2 cents ;)

To some extent I agree with the critique. Would I be able to write an assay like the op in Italian? surely not. Is their marketing annoying? yes, very much. Is the platform perfect? far from this. However - after 3 years with Duo I am capable of having causal, simple conversations, I can navigate most of the websites in Italian, I understand most of the marketing emails, I can write simple emails myself. I trust this is mostly due to DuoLingo - building the vocabulary and quickly recognizing the patterns (and It was not super simple, my native language is Polish, and I was learning Italian via English interface - there was no Polish-Italian course back then, now there is one but it's just very low quality).

Duolingo helped me build a habit, knowledge of words and patterns. During the 3 years I've spent with the platform I made trips to Italy, I tried talking to people, tried to read texts and and explored some grammar myself. About a month I go feeling I've outgrown the platform I started doing 50min conversations on Preply platform and I am now confidently moving into stage where I can build longer sentences, use past and future tenses and irregular verbs.

In my discussions with friends I emphasize that IMHO Duolingo alone is not going to teach you (complete) language. If you have a goal to learn a language (in general, not on Duolingo) and you use it as one of the tools - it could be really helpful.

I used Duolingo a fair bit in 2015–2017 to improve my Swedish, and generally enjoyed myself. Having not touched it for most of a decade, I downloaded it earlier this year to try my hand at basic Greek and wow but it’s gone downhill. Everything is massively over the top, all subtlety has left the system, and when I stopped after a couple of days because I couldn’t deal with the intensity they sent me nagging messages for over two weeks in more and more pleading tones trying to get me to come back. I’d never use them again at this point.

Edit: just went to delete my account and they’ve got a tearful owl above the “Erase personal data” button to try to guilt-trip me into staying. https://drive-thru.duolingo.com/static/owls/sad.svg

I agree with some aspects, and think the author perhaps misunderstood some others.

> If I collect 100 XP, what does it mean for my language skills? For that matter, why do I collect extra XP when I receive a potion? Can the XP I collect be used in a way to carefully guide me towards the specific language skills I would explore next?

Using XP to guide the user towards a particular path is an idea, but it's just not one that Duolingo uses. The purpose of XP in Duolingo is simpler: people like numbers to go up, so they get XP for using the app. It also enables an ecosystem of rewards; I'm generally not a competitive person, and there have still been days where I took a few more Duolingo lessons because I was close to completing a "daily challenge".

Similarly, friend streaks, leaderboards, etc, all have innately appealing hooks. They won't all appeal to everyone all the time, but one of them will appeal to someone some of the time. If they get you to practice for 5m a day more than you would've otherwise, I think they've served their purpose.

Broadly, I agree with other comments about expectation management and time commitment. Could you get yourself to a solid level of understanding in a new language only by using Duolingo? Possibly, but you'd need a lot of dedication and hard work, and much more than 5m a day. If you really wanted to learn a language, and had the time, there are much more effective ways to get there.

Duolingo isn't really built towards encouraging that kind of intense learning, because they know most people who download the app are looking for a bite-sized learning experience, and are willing to accept bite-sized results in return. For myself, I can say that after a couple of years of leaning Spanish on Duolingo, with no previous experience in the language, and an average effort of probably ~10m a day (many days less, some days more), I can read texts if they aren't too complex, follow a casual conversation, and communicate basic things. That's way more than I would've been able to do if I wasn't using the app.

Duolingo is surely flawed, but realistically I don't see any other way how I could have progressed in French by spending exactly 3 minutes per day with near-zero mental effort. I do it on auto pilot before going to bed, usually being dead tired after work. After 1000 days (so like 50 hours) I can have simple conversations, I can read and I have a rather big vocabulary.

Of course learning in other ways could have given me more in 3 years but the amount of time and efforts would be orders of magnitude bigger, impossible at this point in my life.

I think the trick with Duolingo is to resist the temptation of easy paths the damn app pushes you into.

* Maintain the streak by progressing in the course. Don't redo old lessons, don't do pairs matching or other side quests.

* Ignore XP and leagues and challenges and any other shit.

* Ignore music, math and other courses

* Stick to 1 language, at most 2.

Just do N lessons per day (N=1 for me) and you'll most likely see progress. The lessons are too easy IMO, I rarely make mistakes which is a strong signal. I have to make them harder on purpose: I don't look at the screen to force myself to listen instead of reading, I close the right half of the screen with my palm when I need to do pairs. Even then the progression is too easy and too slow BUT it's a progression.

MostlyStable - 2 days ago

Duolingo's marketing of "learn a language in 5 minutes a day" or whatever their similar slogan is, is bad. Duolingo won't teach you hardly anything at all in only 5 minutes a day, and even with considerably more time (30 minutes to an hour a day), on it's own it is unlikely to teach you a language. However, in combination with other learning tools like classes, immersions, comprehensible input, etc. It is a very valuable tool. I finished the German class in about 2 years, and I found it helpful, and wished that the Duoloingo German class continued further than it did.

Yeah, I agree, I don't like aspects of the league, and I think that the way they apportion XP encourages less-than-idea ways of spending your time. Basically, if you use Duolingo exactly the way they encourage you to use it, and only that way, you won't get much out of it. But if you are self directed, recognize the ways in which it is useful, and use it as another tool alongisde the rest of your learning, it's really helpful.

Like I always say to my friends & family who are complaining about Duolingo not really teaching anything: it beats doomscrolling, what else do you want?

Finally a good critique of Duolingo, couldn't have written it better myself. A fresh take separate from the cliche everywhere on the internet that you can't learn an entire language on Duolingo itself which I've heard a thousand times at this point. (Currently "learning" French on it, but going to quit cause have been guilty of cheat-streaking myself).

Yes, the social aspect is trash. The "path" is trash. The leagues/incentives don't make sense. It's just a bad app. This blog made me realize that it could possibly be better in concrete terms. And without even going against their bottom-line. Like, it could still be gamified and what-not, but BETTER. But it isn't. It is just a poor design. YES, language-learning takes effort and many different sources, and YES Duolingo-like apps can only hope to be like a SNACK, but they could still be much better, ugh.

crvdgc - 20 hours ago

Duolingo is useful, but not efficient. When people say I want to learn a language, they often mean I want to learn this language efficiently, e.g. to be able to write an essay like the post says after a realistic period of time.

I personally don't believe its pedagogical deficiency is mere incompetence. The whole business model is to keep you on the platform as long as possible, so why would they make you learn faster rather than just enough to keep you there?

As a long time user before, I have observed a lot of mechanism changes that bear out this observation.

From a 2019 Forbes article [0]

> Duolingo has gotten bad press from writers who try the app and don’t learn much. But Von Ahn promises only to get users to a level between advanced beginner and early intermediate. “A significant portion of our users use it because it’s fun and it’s not a complete waste of time,” he says.

> He’s been logging 15 to 20 minutes of French every day since November, and when asked to describe what he did the previous weekend he says, “Je fais du sport. Je suis mange avec mes amis. Je suis boire du biere en un bar,” mangling his tenses. (Rough translation: I play sports, I am eat with my friends. I am drink beer in a bar.)

> Bob Meese, Duolingo’s 42-year-old chief revenue officer, has been studying Duolingo Spanish for more than six months. In response to the question, “¿Hablas español?” he freezes, then says, “Could you repeat that?”

Also, having worked in the language learning industry myself, readers may be curious to learn that Duolingo is seen as a pariah that no one takes seriously as a learning tool. And I'm not one to use the term "scam" lightly, but if that word is to mean anything, then it definitely applies to Duolingo!

nikolay - a day ago

Duolingo is gamification gone wrong, with most of the development effort spent on childish animations! I've been trying to learn Greek for four years using it daily, and most of the time, I'm just trying not to drop out of leagues or ruin my streak, and not so much trying to learn as the gamification incentive is to waste time, not to learn and increase my chance of dropping. What a joke! If I put all this effort into real language learning, I would have been a fluent speaker already. And I'm literally nowhere!

Fraterkes - a day ago

The thing that sorta gets me about Duolingo: If it became mainstream for everyone to do what is essentially 5 minutes of anki every day (which is kinda the Duolingo pitch), language learning would be kind of a bad candidate. If you spend 2 years memorizing 400 words you still aren't close to knowing a language. But there are many situations where memorizing 400 distinct things is pretty useful: countries, capitals, recipes, history etc.

forgotusername6 - a day ago

I have a 2000+ day streak on Duolingo, mostly learning Russian. The app has got progressively worse since I started, for a while just giving me the same lesson every single day. I of course finished the course years ago, but I keep up with my one lesson a day to keep the bird happy. I find the UI incredibly annoying, I've disabled all the sounds and animations that I can. You might ask why don't I stop? Well I want to keep up my Russian, and the one lesson a day keeps my brain ticking over.

I was happy to read some comments here reinforcing the experience I had - that immersion is absolutely necessary. For the sake of anyone who might ever be interested, and because today marks literally one year since I began doggedly learning Danish, here is how I get immersion while being thousands of kilometers away from a community of speakers (currently live in Brazil, before that Switzerland).

- The system language in my cell phone is Danish

- I started with Duolingo every day, but then after some 3 months or so it wasn't so fun/effective anymore.

- I read Danish news every day. Most often just the first two paragraphs is enough, but I make a point of understanding everything. Whatever is first on the webpage and is non-trivial. I know more about Danish handball than I ever thought I would.

- I found some Danish bands that I really like and I listen to them very frequently. For now I don't actively try and translate all the lyrics, since this is my "relax in Danish time", but I have noticed that I can pick up more and more - only then, I go and confirm to see if this is true or to learn what it actually is

- I read reddit posts in Danish (including on jokes) and I often try to write some responses myself. I am still ramping this last part up, but my procedure is: I first write in whatever flows: true Danish, broken Danish, a mix of Danish and German. Then before posting I ask ChatGPT to correct to C2 Danish and explain every little correction. I usually learn a lot doing this.

- I read LinkedIn posts in Danish, wikipedia in Danish when I'm searching for a new topic, and asking ChatGPT for responses in Danish when I have the time to read it through.

- I am also now increasingly exploring using Danish dictation on my computer, but this is still very much work in progress.

- Plenty of podcasts as time allows (I don't drive to work)

- Movies, first with subtitles in English and then in Danish

At this point, I feel that I can:

- understand a good enough portion of what is said in movies and songs to make me proud and motivated, although Danish pronunciation is notoriously difficult for the non-initiated and of course I am still a beginner

- understand written texts where the main difficulty is finding vocabulary rather than picking up the grammar

- I can actually understand some written Norwegian and Swedish, which is a pretty cool plus!

A lot of Duolingo criticisms to me read like someone saying "I was walking on a home treadmill for 30 minutes every day but I didn't really get in shape until I started spending 5 hours each week in the gym with a professional trainer."

Yes, obviously an actual class with a qualified teacher is going to teach you a language faster than Duolingo. Obviously you will learn faster if you move to a foreign country or if you have people around you to regularly speak your target language. Obviously you can cheat at Duolingo and not learn anything, just like you could turn the speed way down on your home treadmill and not really get any exercise.

But the treadmill, used properly, is still significantly better than an extra 30 minutes sitting on the sofa, and a ten minute language lesson will still teach you more than no language lesson at all.

Each time I read this kind of feedback, I wonder if there should be a free, community driven, alternative to Duolingo.

- Content may be provided by contributors (like Duolingo did for many years)

- It could be supported by donations (I believe the costs can be kept low)

My feeling is that lots of problems with Duolingo are caused by monetization (and many things were better in Duolingo a few years ago).

I'm still not sure of how it should be designed and what we need exactly. One of the problems is also to get enough contributors. I'd be interested in hearing more thoughts on this.

As a hobby, I started building an alternative to the Duolingo Stories feature (https://lingostories.org), but it's still fairly limited.

Anecdata: my daughter, when a rising high school sophomore in 2023, used DL to skip a full year^1 and join upperclassmen in Spanish 3. She went on to take AP Spanish, earn college credit w/ her AP test score, and join the Spanish National Honors Society. She credits DL w/ giving her the confidence -- and vocabulary -- to make the leap when she did. Of course that doesn't mean critiques aren't valid, and YMMV, but it does help show that DL isn't necessarily useless, either.

1. Despite US high-school language classes generally having a (usually deserved) reputation for failing to impart real fluency, our town's language instruction is actually first-rate.

logicziller - 16 hours ago

Having no prior exposure to any European languages, I tried using it for learning a bit of German, just to be able to sing along with some songs while also understanding what the words mean. I learned about 1500 words, but about a year later I watched a language training video and it became obvious to me that I have been pronouncing S, Z, and ß all wrong this whole time and made the wrong pronunciation a habit that I'm having difficult breaking. It taught me nothing about the alphabets and how the combination of certain letters or their position in a word can change the sound. Clicking through the words and advancing to the next level probably made me go too fast without giving me enough time to really absorb it. If I repeat a test, it's the same questions being repeated so it kind of feels like rote-learning than actually giving me an opportunity to reflect on the mistakes.

It also allows you to skip through the audio and speech tests, so these shortcuts make you chase XPs rather than actually learn the language you originally set out to learn. My biggest pet peeve about this app is that I have absolutely no idea if I'm pronouncing words correctly. Even if I intentionally pronounce a word wrong, it'll tell me it's correct.

I wouldn't say I learned nothing from it. After all, there is nobody I can speak with, so Duolingo made something impossible, possible for me, but it hasn't made me conversational at all. If I watch a German movie or a TV show, I can understand a little bit by looking at the subtitles, but the audio seems to go way too fast for me that I pick up just 1 or 2 words from a sentence. I'd imagine if someone asks me a basic question really slowly, I might be able to answer it, but if I'm in a group or something, words will just fly by too quickly for me to be able to comprehend anything.

One thing it did is make me motivated. After learning so many words, it made me pursue training courses by professional language teachers, and eventually I will join an actual classroom. I don't think I'd have gone all the way if I hadn't got my first start with this app. After all, my original motivation to learn was just cultural / music, and not because I want to move there or that it'll help professionally, but after having coming this far, it made me think I should pursue learning more seriously and become fluent.

Duolingo and many other apps avoid the hardest and most essential skill: translating from your language to the other.

It's often easy to guess what words mean especially with the help of cognates and other similarities between languages. 99% of Duolingo mobile is like this. Even when you see words in your language first, your task is to tap the presented foreigin words in order.

You'll never learn to speak this way. The best way is to flip the order:

    The language is difficult -> La lengua es difícil.
But that's a slog by comparison. The dopamine rush isn't there, which I guess is why no one does this[0].

I actually wrote a script to build Anki decks from Duolingo and Busuu[2] which did this. The front front is a short sentence. The back is a transliteration and translation. Then I discovered Mango Languages (free through many US public libraries) that's the same with great audio and a pretty good flash card system.

I used that strategy 2 hours a day for two months, and I learned enough Italian to argue with a cab driver whose meter "non funziona."

I agree wholeheartedly with the sentiment of the article, but cookie clicker IS a game worth its salt. Input mechanic difficulty is not the sole factor to consider when determining the quality of a game loop.

I first used Duolingo back in 2018. That was how I started learning French. I majored in Classics in college and had taken Spanish all eight years of middle school and high school, so my vocab progress was very fast. Within that year, I felt like Duolingo had become too slow, and decided to switch my learning over to reading books and watching movies in French.

Earlier this year, I got back on Duolingo because my partner and her brothers were trying it out, so it was more a social thing than anything. I was on it for about a month before we all agreed that the quality was too poor and the pace too slow for it to be worthwhile.

Duolingo is a case study in a good-enough-to-ship product that needed improvements and instead got dark-patterned into something much, much worse than it had been previously. I'm sure there are many superior platforms for language learning online today. I've gone back to books and movies. I'm currently enjoying watching Blaise le blasé (a Quebecois cartoon) and reading Chair de poule (Goosebumps in translation).

torginus - 13 hours ago

I think this criticism can applied to most SV products/companies. What they care about is:

- Being seen as a new and hip way to do a thing

- Making sure their approach scales to lots of users

- Making the first user experience and onboarding seamless

What they are willing to give up:

- Long positive term user outcomes

- Sustainability and supporting complex user needs

It seems their goal is to extract value from the users by promising them a better/easier to use/cheaper product then hooking them and stringing them along until the users grow frustrated enough. I'd list some examples of this exact business model, but there's too many to count, and I'm sure most people here won't have any trouble coming up with some of their own.

Look, Duolingo is obviously not the only thing you use to become proficient in another language. It's not perfect, it's gamified, it's over simplified - it's a tool in the toolbox.

That being said, it's helped me immensely with both polishing my Dutch (I passed my state exams a while back but there are still so many words I don't know), and I'm now learning Japanese.

Yes, Duolingo does not teach you directly all the intricacies of Japanese grammar. That's because it's a dumbed down, spaced repetition app. If you're actually serious about learning a language you'll see that pretty much from the start and like, buy some Japanese textbooks or something to supplement what you learn from the owl app.

I'm currently using Satori Reader and have bought a manga to practice my Japanese reading. My grammar is still woeful, so I'll need some other material to work on that and get a real understanding.

Anyway, I don't really disagree with the author on their criticism per se. But I think the criticism applies to a bunch of language learning methods...

ggregoire - a day ago

My only criticism of Duolingo is the monetization. The ads on the free version are unbearable and makes me want to never use the app again. Also as soon as you stop using the app, they spam your inbox with emails every 2 days such as "Duo misses you so much! <sad emoji> Are you giving up on learning?? <crying emoji>". This made me uninstall the app.

Otherwise I don't share the criticisms in this comment section. It's a fun educational game to learn a few words in other languages. I don't think it's misleading anyone into thinking they will become polyglot by using Duolingo. I wanted to learn a few words of Japanese while waiting for a flight to Tokyo and it did the job.

dougdonohoe - a day ago

I can relate to this post - great thoughts!

I took Spanish in high school and college, so had a rudimentary understanding of verb tenses and some vocabulary. Before I walked the Camino de Santiago el Norte (45+ days in Spain), I used Duolingo to brush up on my Spanish.

It helped my reading most, my speaking a fair amount and my listening/conversation the least. I was able to ask questions, but was often flummoxed at any reply that wasn't the most basic.

I grew to hate the gamification, but was addicted to my "streak' also ... using math lessons when I didn't feel like doing a Spanish lesson. The so-called "leagues" were kind of useless since the same people weren't in the league from week to week. Any friendly competitiveness to "learn more" was lost when randomly assigned to a different group each week.

I finally abandoned the app this spring.

I'm trying Babbel now since I'm going back to Spain for a month and Patagonia next year.

I think it's important for those responding about their Duolingo experience to include the tier that they are using. Specifically, I wonder if the conversations with AI, and the "explain this" feature in Duolingo Max change outcomes? I'm new to Duolingo, chose the max tier, and feel that I'm learning quite a bit specifically because I am having simple conversations in French daily (albeit with an AI that seems to me to have questionable hearing at times). I haven't used it long enough to provide insight or even judge the platform, but for those using the more expensive tier(s) I wonder your thoughts...

apple1417 - 21 hours ago

2800 day streak here, primarily in Finnish. I haven't been a fan of the app for a long time, but the problem I've always had switching is the question: What else? There might be a thousand different Spanish courses, but for less popular languages there just aren't many choices, the fact that they still host one is great. Yes I haven't really learnt much, it's more maintaining what I do know, but I'd've lost it without.

Incidentally I do think Finnish is one of the cases where it could work well. The way I see it the difficulty in learning Finnish is primarily learning an entirely new vocabulary, the grammar and sentence structure isn't that hard, and Duolingo could work well to teach you thousands of new words. The problem is they have a very limited amount of exercises, to the point my phone's auto complete can solve half of them.

I like the realistic idea of Duolingo. I know I'm not going to get fluent with it and I'm not trying to, but I do want a good app to expand vocabulary and basic structures that I can do in 30 minutes a day. And I'm a sucker for streaks, but not all the other gamification. I don't need gems or XP or potions, just a streak to form habits, which I am bad at and need that positive affirmation.

Does anyone know any alternative apps that achieve the same goals with less of the fluff?

projektfu - a day ago

I think Duo could be a good way to get started on language learning, but it is not effective on its own. What it lacks is an obvious way to graduate from its call and response mechanic to synthesis, as in creating your own sentences and participating in conversation.

Tandem was a good way for me to improve my Spanish to the point that I felt comfortable traveling. I dropped Duolingo pretty soon after starting on Tandem. Language learning is much more than memorizing words. Unfortunately, Tandem is also basically a dating site for many people, and scammers are using it as well, and this makes it hard to use consistently for language learning.

Once you get the minimal confidence that you think you could find your way back to the airport or bus station in another country, you really should just go visit. Couchsurfing really helped me meet people in many cities. I don't know if the community is still as strong, but it used to have regular meetups of people within a city who are interested in talking with foreigners. You don't need to stay on people's couches if you don't want to.

A lot of people seem to be learning English through multiplayer online gaming. I do not know if this approach works for learning other languages, as I am not inclined to participate.

I can't stress it enough, though. Any language learning approach that isn't writing or conversation is going to max out at a very low level.

Duolingo was amazing for learning the Russian alphabet, something I struggled with from YouTube videos, etc. I can confidently read Russian nowadays (although I may not understand everything). I did get quite far in the lessons as well, but I don't have a high opinion of them. There were things I've learned from Duolingo that I said to native Russian speakers who were like... "we don't say that".

Note: The alphabet lessons are separate from the main content.

Depends what you compare it with.

Having a Spanish-speaking language buddy or actually living in Spain or Mexico is much better than Duolingo for learning Spanish. (xx)

Watching hours of brainrot youtube doomscroll is much worse than something like Duolingo.

The niche for Duolingo is the latter. Obviously it can't compete with the former. You don't need an opinionated blog post to realize that.

The removal of the forums that the author mentions was what finally ended my 1000ish day streak. It was the most important part of the app for me, the way each question would link to a forum topic and users would discuss the various subtleties.

My assumption, despite plausible claims of moderation issues, is that they removed it so that their expensive AI addon provided more value. But it was the last straw for me.

Duolingo is a good example of terminal enshittification.

"[I]f it’s our content, as in, like, our learning content, there’s so much of that - thousands and thousands and thousands of kind of sentences and words and paragraphs. That is mostly done by computers, and we probably spot-check it. But if it’s things like the user interface of Duolingo, where we say - like, you know, the button says quit, and we have to translate, that is all done with humans. And we spend a lot of effort on that, but that’s because each one of those is highly valuable.

Yes, the button that says ‘quit’ is more valuable than the learning material, which is only ‘probably’ spot-checked."

What you all (most likely technical people) need is someone who teaches HOW a language works.

Please check out Michel Thomas.[1]

You will be speaking sentences and understanding how words connect together in the first 20 minutes.

He is the only reason I speak any Spanish at all, and it’s a borderline miracle I can now speak fluently despite being the absolute worst language learner as a kid.

The BBC made a documentary about him (teaching French) where he goes into a UK school, says “Give me your worst pupils” and then teaches them most of the years long curriculum in a couple of weeks.[2]

He was also in the French resistance a Nazi interrogator in the 2nd world war. [3]

An absolute dude. Would be my #1 historical dinner party guest!

I did Language Transfer for Modern Greek and found it excellent. The host and creator is a native Greek speaker. I cannot recommend it enough!

Gamification isn't about turning work into games, its about turning work into gambling.

One thing that I have found Duolingo helpful for is kana and kanji practice in Japanese. It's better than flashcards in that it also gives you stroke order.

Duolingo is a mobile game with a language learning gimmick, not a serious learning tool.

There's a lot of hate for Duolingo.

My brother talked with his cab driver on Spanish. And is able to understand Spanish at a much better level. All from only using Duolingo for a year. So it seems like, it does work. At least with anecdata

Duolingo has been around for so long that I feel like there should be a wealth of case studies showing how folks have used it to actually learn new languages. I've yet to see one, personally. (But perhaps I'm not looking hard enough!)

"Big tech embraces blitz-scaling: the primary goal is neither financial sustainability nor the quality of materials but making the number of users grow."

In most cases, there are no materials. It's intangibles only. Duolingo, for example

There are exceptions. High quality materials are a goal for Apple

I really enjoyed your opinionated article. You put the finger on the weak spot of Duolingo: It's an ineffective way of learning a language. With the advent of AI they, we see a lot of different approaches pop up that might actually be more enjoyable and which might put Duolingo in jeopardy.

However, you also touch upon an other interesting point, namely that learning a language involves many skills, that even differ from language to language. One app pretending to learn it all probably won't work.

I have been making my own language learning app (lingo llama, check out the site :)), and learned the hard way that actually learning a language is not straightforward, and very different for every user. For example, if you want to learn Spanish, and already know Portuguese, you want a different approach then if you come from Japanese. Maybe using tools to learn parts of the language is the way to go.

Anyway, I liked your read, thanks!

Duolingo is great at gamification and terrible for actually teaching you the language. You memorize a ton of random words without really learning how to put everything together.

I found Babbel to feel much more like an app designed by language instructors.

I repeat: Duolingo is not a language app. It’s a gaming app. Don’t use gaming apps to learn languages.

Seconding the recommendation of Language Transfer. It helped me learn Spanish grammar remarkably quickly and easily.

The way to learn a language is to immerse yourself at location.

I bought Rosetta Stone for a similar purpose.

They cannot give you a chart or synopsis to save their lives. They are quite weak on tenses for this reason.

I feel like people overestimate Duolingo, and end up disappointed.

I am convinced that doing some Duolingo while in the bus is a lot better than swiping stupid videos on TikTok.

Will it effortlessly teach you a language? No. There is no such thing, and Duolingo does not pretend there is. But it will regularly expose you to sentences in the language you are trying to learn, which is most definitely better than nothing.

Now if you are motivated enough to spend 1h per day learning, of course there are better ways. But I thought it was obvious that the "I want to sit back and enjoy" attitude won't teach you a language.

What is a non-opinionated critique?

scarface_74 - 14 hours ago

I used DuoLingo two or three years ago to try to learn Spanish. I knew a little of the basic grammar from high school and some words. By the time I got to lesson 20, I was completely loss. I also got sick of the gamification and just the grind of it. I just stopped.

That and I realized the continuous click buttons got tiresome.

Then, earlier this year my wife and I decided that we wanted to start spending at least a couple of months every year in Costa Rica starting next year and maybe alternate between there and other Spanish speaking countries in us time zones.

This time, I had ChatGPT and a Trello board I put together of concepts and categories of words I wanted to learn based on the CEFR level A1 list. I would create various drills, ask ChatGPT to explain concepts, etc. I became more focused on production - mostly writing. ChatGPT is a good teacher to get through the list of topics of my known gaps.

I even asked it to summarize the most important current event at an A1 level and ask me questions.

As far as speaking, I used Apple’s voice to text and not the better one built into ChatGPT. It’s pretty good with my English native southern twang so I figured any mistranscription in Spanish was caused by my bad pronunciation. The one built into ChatGPT is better. But that’s actually a bad thing when trying to pronuncie words correctly.

After a few months of ChatGPT, I did recently go vac to DuoLingo. I do the first exercise in a unit, then see if I can skip the rest (which it does let you do). If I don’t know vocabulary or a concept, I go back to ChatGPT for drills.

Being able to listen in Spanish in real time at an A1 level is the next step. I can use ChatGPT for that first and then watching kids tv shows in Spanish

I want to learn German. What should I use? I planned on starting with Duolingo, but I'm not sure anymore.

thinkingtoilet - a day ago

I couldn't stand Duolingo because of the gamification. I'd complete a section and then there would be four screens telling me I earned points, then another screen saying I earned a different type of points, then a screen asking to share my results, etc... Each lesson was only a couple minutes so this ends up taking a non-trivial amount of time. Also, the sentences were often times nonsensical and nothing you would use in a real conversation. However, I would sign up tomorrow if I could get rid of all the gamification nonsense. There simply aren't that many half-way decent Hindi options out there. Pimsler is by far the best, but it only has two levels and you can only do it so many times.

Personally, I found I cannot learn languages through apps like Duolingo, nor through regular education.

What works for me:

- associate words with their meaning. This means not trying to translate words into their counterpart in a different language. So no flash cards with words on both sides, but with pictures.

- listen to music. This helps me develop a feeling for the language, where I understand the beginning and end of words, and intonations.

- watch simple shows in the foreign language. Kids shows, cooking shows. Stuff where the context is obvious, so once again I am not secretly “translating”.

- going on holidays or booking a conversation with a language coach. Because understanding and production are two different brain areas (wernicke vs broca), so there are languages which I can understand, but not speak.

If it's 2025 and you people still use Duolingo, then probably they just like to use Duolingo. It's like people who grind grammar books – both ways to learn language are dead ends, but make people feel better because "look I have 1000 days streak in Spanish" ("I can write conjugations for 100 verbs").

If DL taught me something, it's that it's better to completely ignore any gamifications, streaks, "hours of input", levels and other metrics that language learning services give you. It's easy to get into trap of using them as KPI of your learning process, and not your ability to speak to other people.

Duolingo is terrible†, but proper gamification combined w/ LLMs for real conversations could be an incredible learning tool. (I might build this if no one else does.)

†It can be useful for going from absolute 0 to epsilon, just to kind of get familiar with the language, but if you're using it more than like 2 weeks, you're seriously wasting your time (vs. reading material in the target language, watching TV in target language, trying to talk w/ people in target language). Anki, too, can be a trap that feels like learning but isn't, really, in my experience.
