DUOL shares have fallen more than 78% from their May 2025 high, and that’s before its nearly 25% fall in premarket trading today.
I’ve said before that one of the very few good things generative “AI” may do to the world is accelerating the enshittification cycle so much that it kills stuff that was already terrible and a drain on society (social media; platformization; curation algorithms…). Speaking as a linguist who speaks 4 languages and has read the literature on second language acquisition, it has always been my position that the Duolingo method is useless—it feels like you are learning a language, but you can spend infinite hours with it and gold a full tree and you’ll still get nowhere, and if you put a fraction of the time in about any other method, including doing pen-and-paper drills with old-fashioned paper-based textbooks, you’d have progressed much faster.
And old-fashioned grammar drills suck, too. It’s just that Duolingo really, really sucks.
(Methods that work better: 1) Find an intensive “conversation”-type course, or anything that is labelled as “natural” or “immersion” or “storytelling” methods; or get tandem partners; or online coaches such as in italki; failing that, join a conventional language course, the more “intensive” the better; work on these until you absorb basic grammar and vocabulary, focusing on spoken language not writing; 2) Once this bootstrap period is over, start talking to people, watching media, or reading stuf that interests you, in large quantities and every day; do not wait until you’re “good” to move into the input stage, start actually using the language for things you wanted it for, as soon as possible, which is sooner than you think; partial comprehension is fine.)
Of course I hope Duolingo dies horribly in a fire after it backstabbed its workers with the “AI memo”, but even if it didn’t, the world is better off without it.
One lesson we can get from this: Consider that overnight 25% drop in investment, which may well prove to be the coup the grâce. It was not caused by Duo losing users or enshittifying with “AI”, but by the opposite: investors mass panicked at the company setting its target revenue too low, as in a mere… 1.22 billion, rather than the 1.26 billion the investors wanted. Now the reason Duolingo is not chasing that higher goal is that they’re seeing the writing on the wall, and went into damage control mode: they’re pulling down a bit on squeezing their current paying users and trying to improve the experience of the free tier, in an attempt to reverse the bleed and bring in more customers.
In other words, Duolingo tried to slow down the slightest tiny bit on enshittification—3% less cash—and this already got swift punishment from the market gods. With capitalism, there is no long-term thinking: you’re expected to provide the richest people on Earth with infinite growth of their ever-increasing profits squeezed from customers paying every month more and more, now and forever, or you’ll be taken out and replaced by someone willing to try.
Edit : I got lots of questions like “if not Duolingo then what do you suggest?” The full answer is “literally anything else”, but I’ve cleaned up a couple of my longer answers and wrote these blog posts: 1) on comprehensive reading, 2) on tandem exchange.
What do you think of Rosetta Stone? I liked it’s pseudo immersion, and have debated on trying again.
I am 900+ days streak on Russian->German and I feel that it went down massively since I began doing it 5 years ago.
They been forcing daily tasks to call Lily since last year and that shit is fucking annoying. The dialogue is basically weak an half the time it is just not working. Also, they probably used my voice for AI training without asking me ofc, so fuck that. I stopped doing calls in a week.
Then they came up with podcasts. Good idea imo. But they did it weirldy. Character, say Lucy, would talk in Russian while person on the call would talk in German. It would made much more fucking sense if they made it entirely German. At the very least podcasts were decently written that felt that it was written by a human.
Now, they did change podcasts to be in full German. But they also destroyed stories that previously been written really well and podcasts too. Stories and podcasts now are entirely AI generated and they fucking suck donkey balls. Not engaging, overstretched. Character interaction that was previously established is gone. side characters that appear only in certain stories are replaced by a narrator. This could be so super cool if done right. Calls, podcasts and stories could be the driving feature. Instead it feels dry and stupid. And doesnt even teach you much.
All said, I use cracked Duo MAX and paid them 0 cent over these years.
I know several people who are trying to learn new languages for either fun or actually following courses and it is noticable how less engaged with the language people are who use duolingo. Dont think any Duolingo main ever dropped an interesting language factoid on me.
I feel like people criticizing Duolingo for being inferior to talking with native language speakers or a traditional language class are kind of missing the point. It’s like saying 10 minutes of slow walking is inferior exercise to an hour of HIIT every day. Yeah true but people actually use Duolingo. The whole point is that it is fun and doesn’t feel like a chore. It’s probably why so many people around the world have learned English by watching American and British TV shows. Is that an optimal learning method? No, but the best exercises are the ones you actually do.
Right, except OP and the research suggests it’s not effective, even though it feels like you’re doing it. So yes, 10 minutes of walking a day is interior to an hour of HIIT, obviously. And yes 10 minutes of walking a day is better than not walking in a day, for your health. But no matter how many days in a row you slowly walk 10 minutes, you’ll never be able to run a marathon. It just doesn’t do that.
So if everyone’s goal with Duolingo was to vaguely know some words in a language they can’t communicate in, and it was just a brain exercise like a crossword, then sure. No harm done.
But that’s not most people’s goal, and what the research shows is that for all the time people spend doing it, they could have spent that time doing something else and actually made progress towards their goals.
Right. The point I’m making though is that for the majority of Duolingo users, if you take away Duolingo you don’t get something better. You get nothing.
Only on lemmy would people be cheating the demise of a language learning app, no matter how gameified.
Right, but is it a language learning app? Or is it a “play games with aggressive owl” app with a language learning theme? Because if after 365 straight days of playing games with owl you cannot use the language you’ve been “learning” to communicate, then you aren’t learning a language. And if you’re not learning the language, then what are you doing with the owl?
You absolutely will learn with Duolingo, the “games” are literally saying, reading, and writing things in a foreign language. There’s nothing else to it.
my lemmy client is a humanities app because on it i learn how dedicated people are to completely missing the entire point
Thanks, I just woke my partner because I burst out laughing. Comment of the week for me.
I also feel like a lot of the critisism of Duo really, I dunno, miss the purpose? Of Duo entirely. Or just language learning.
Especially as someone who isn’t young.
Duo is not going to make anyone fluent. No single program or method will. It also isn’t, for most people, something that will make you educated in a language in a day or a week or a year, or probably ten. Nothing short of total immersial will do that.
It also feelslike, based on how critics talk, like they go into Duo trying to learn with a method of like, “Manzana is Apple, Hola is Hello” etc. Instead of doing with a mindset of “Manzana is a round red fruit” and “Hola is a friendly greeting.”
Basically complaints feel like they come from someone who just, expected way more out of it than its trying to do.
Also, lesrning to speak a lamguage with any app really is not going to work, once again, it needs immersion. But that that does not make the app bad.
That said, I have used Duo for mamy years now, across several languages, Spanish, Norwegian, Japanese, and I tried the math, chess and music. Its honestly, not as good as it used to be, but I blame the stupid hearts/energy for that. For a while Inwas using the “fake classroom” trick to get unlimited play, but they stopped that with the update in mid 2025. This biggest problem with these energy systems is that they punish mistakes. For learning lamguage, mistakes are going to happen, a lot, and punishing mistakes is very bad for progress. At some point, just as you might be stumbling but “getting it”, suddenky, you can’t try anymore, because you run out of energy.
I also hate how it punishes using, gramatically weird but correct phrasing (in English), that more closely matches the structure of the target language. Because its helpful for learning the struxture of the target lamguage to do the answer in a similar gramatic structure in your known language.
Also, they are really bad about using sysnonyms for some words when more nuanced translations would be better. The one really easy one is translating “Me Llamo Ramen” to “My name is Ramen”. When its actually “I am called Ramen”. Or probably better, “They call me Ramen”. " Me nombre es Ramen" would be “My name is Ramen”. It seems “nitpicky” but later llamo is used in relation to call/calling, and being consistent would be better for learning. Also, based on my anectodotal moments, a lot of non English use the “I am called…” structure of speaking.
Duo is not going to make anyone fluent. No single program or method will. It also isn’t, for most people, something that will make you educated in a language in a day or a week or a year, or probably ten. Nothing short of total immersial will do that.
That’s just patently untrue. School systems in most non-English speaking countries spit out fluent English speakers after a time investment of fewer than 4hrs/week, for a maximum of 8-9 years.
Don’t get me started on their translation of gustar as “to like”, which is just totally backwards.
(In Spanish, you don’t say “I like it”; you say “It pleases me.” Instead of “I love it”, you say “it enchants me”.)
Duo is not going to make anyone fluent
One of my friends has 2500 day streak in German. He doesn’t live in Germany and I am pretty sure he has no one to talk to in German either. He barely speaks it. I couldn’t strike a conversation with him.
I’d apply similar situation to me. I haven’t been talking much in my motherland language for over 10 years. (my mother tongue is another language) Even if I understand everything perfectly, I am insanely rusty on speaking it and use wrong word forms all the time. Practice is much more important than just plain learning words and rules imo.
Oh yeah. Its been a while since I had the whole like/love etc words but if I recall they pushed gustar (probably) aslike, but later uzed it in way that suggested like, “I love it more than anything.”
Like maybe don’t imply it means simply “like”.

Man i love to hear the news about Duolingo and to hear a linguist’s opinion on it. I’ve always loved languages and have basically always had one that I’m studying at any given time. Of course I’ve tried Duolingo in that.
I moved to Denmark in 2024 and have been learning the language. I have a bunch of friends and acquaintances in various stages of learning it, to varying degrees of success. It’s been my running theory that Duolingo is the most antithetical to success tool you can use. It uses up effort and time for almost no result, while making you feel like you should be better because you’re now “level whatever”.
Immersion and trying and failing are so fucking good for learning, it’s insane. I’ve definitely been too hard on myself in the past comparing myself to people who have learned by living somewhere and how much better/faster they’ve learned.
It is my pleasure to inform you that the research supports your conclusions on all counts :)
I fully agree with your insight on how Duolingo sets you up for failure, and it has another trap, too—one common to all methods that are based on “diligently do these drills every day”* : You think that you should be getting somewhere because it’s so boring and it sucks so much. You did the work, right? You’re suffering, therefore you must be levelling up. Then after 4 years of doing French grammar drills on school or French vocabulary drills in Duolingo, you still can’t even ask for directions or read Le Petit Prince, and you figure it’s because you’re such a lazy loser with no discipline who should have drilled more, instead of spending all day browsing Instagram or playing Animal Crossing.
When actually what you should have done was to browse Instagram in French or play Animal Crossing in French. Perversely, real language learning—we call it “acquisition” rather than “learning”, to emphasise how it’s an instinctive, subconscious process—happens optimally when you’re in a state of flow where you don’t even notice you’re using the second language anymore, i.e. when you’re not suffering.
* There’s a very limited number of things that you do actually have to consciously drill; mostly writing systems, maybe also the phonemes at the beginning (this part is debated). Luckily, almost all writing systems in current use are very simple and you’ll get them nailed down in no time, as long as you already know the basics of the spoken language (remember, writing isn’t made for foreigners, it’s made for native speakers to represent the words they already know). The exception is if you’re learning Chinese or Japanese, in which case there’s no way out of drilling characters, forever. my degree in Japanese is from over ten years ago and I can read Japanese pretty fine these days and I’m still drilling characters. It is still the case that it’s much easier to learn the characters the way the Japanese and Chinese peoples do it, i.e. after you know the spoken language (at least to a basic degree, say A2 or so).
this is so lovely to hear! Just got to chat with my partner on what you said and it’s so exciting and affirming to hear from a linguist.
I studied japanese on my own for almost a decade. Lots of kanji studying, mostly. My spoken japanese is not great at all, and I constantly feel like I should be way better than I am. It’s been a huge pain point for years for me. Meanwhile I learned Spanish (maybe B1+/B2) growing up, working with a lot of Spanish speakers, having Spanish speaking friends. So very little real studying and I don’t know a damn think about grammer or rules. But I recently had to use it for a few weeks in Spain and it was fine. I’m sure I made a million mistakes but I was understood and could understand.
Small self flattery ahead, be warned.
Now learning Danish, i basically got off the plane and was like “okay someone teach me how to order a beer”. I have been mostly just talking and listening and it’s going so freaking well. A year and a half in and I’m easily B1+ or B2 (confirmed B1 in school but ahead of the curve by a lot). I work in danish(well danglish), can play a board game or drink in all danish and it’s fine (albeit a bit of a cognitive load). I can’t believe the difference in the learning styles.
Needless to say I deleted Duolingo a while back and am happy about it
Godt gået!!
My own Japanese only left the Endless Intermediate Tarpit once I stopped spending all my time trying to drill every single kanji ever and/or optimising the theoretically perfect kanji reading learning order, and started reading stories in large quantities for fun. Since kanji is such a barrier for reading, that meant teenage-level manga with sō-furigana, children novels, and eventually light novels/YA. The alternative is talking a lot with Japanese speakers. In either case the keyword is a lot; it can be tricky to find teen stuff that’s interesting for adults, but luckily a lot of manga is very bingeable (the first one I read in Japanese, Hagane no Renkinjutsu-shi, I did compulsively in one go, all 18 volumes one after the other).
After you have a good handling of the grammar and already know the words of the language, then kanji drills become much more approachable. That’s how Japanese people do it, after all; they’re already fluent speakers of Japanese when they start learning kanji. Thus the existence of material with sō-furigana, and the way furigana are only gradually dropped stage by stage until adult-level material.
I spent an embarrassingly long time spinning gears in the cycle of doing drills, then getting bored and abandoning the drills, then feeling guilty and trying to push myself to go back to the drills—before realising I had long reached the level of “can more or less understand manga with furigana” and was wasting time.

For me, learning the grammar is faster with a bit of book learning. Deriving it all completely from everyday use takes way more effort.Book learning definitely can’t stand alone but it really helps.
@frank
I used Duolingo when I visited Crete and found it totally useless.
I also bought into the Duolingo hype in the early days, watched it enshittified into oblivion, and not shedding a tear for investors punishing it, even if it’s for the wrong reasons.
I’m now doing comprehensible input (reading + videos) and flash cards in my target language. Even though some people poo poo flash cards, I find it a good complement for CI (when I encounter a word from flash cards in the “wild”, it does click better). I definitely need to work on speaking ability.
Fun fact I learned about Duolingo: They don’t have a cybersecurity team
I’m honestly shocked they haven’t gotten hacked more
Hard to know if there has been a hack if no one is looking for it.
My personal pet peeve about Duolingo;”: it doesn’t teach you a new language, it teaches you to translate to your main language. That’s absolutely not how you want to learn a language! You want the target language to stand on its own, not be piece-by-piece translated back at any interaction.
I can magnanimously appreciate Duolingo for the purpose of giving a rough base of a new language, maybe even a little but of vocabulary. I hate everything else about it.
When you first start translation is useful. However you need to get beyond that fast if you are to actually learn.
I tried them out years ago. I had taken a bit of German in high school and liked it so I figured I’d give it a shot.
I didn’t love the gamification aspect. That’s something that applies to a LOT of modern software. I always hated gold stars and stickers as a child in school. I hated the stupid programs my various employers had to encourage coworkers to compliment each other - it’s all a tactic to generate positive emotions and avoid paying people more. And most of all, I saw the rise of mobile games and micro-transactions and skinner boxes. The way some people just go nuts and put hours into games they otherwise wouldn’t just to get some digital “trophy” or “achievement”. Duolingo had a decent amount of that.
I stopped because of privacy concerns. I forget the details now, but I think maybe they were found to be harvesting a lot of data from phones that they were not disclosing. Either that or they pushed out a mandatory terms and conditions update that just said they would be harvesting all of the data? So I uninstalled.
I watched my girlfriend use it last year and it’s so much worse. They have leaned so heavily into “dailies” and “streaks”. It’s like the shittiest mmorpg you’ve ever seen.
I recently started Busuu, and while it feels BETTER it still has a lot of the same stuff. A lot of encouragement to engage in, like, social and community aspects. To get streaks. Idk maybe I would be better off just finding books or something.
Busuu’s not bad: I made it through the first Mandarin course, with the occasional forced social aspect of “write something for the Community to review”. The second Mandarin course is much less polished though, I gave up on that a couple days in after I ran into all kinds of new words that aren’t introduced before their use.
I absolutely loath the “write something for the Community to review” aspect. There should 100% be a way to turn that off.
And make my profile completely private. I don’t want anyone else to be able to see my progress or even know that I’m using the app at all.
I want all the AI slop adopters to suffer and be ruined.
I haven’t found a good alternative for getting better at French or learning Spanish from scratch, but I haven’t tried very hard. Maybe I should replay expedition 33 in French…

I’ve spent many, many hours trying to learn French in Duolingo with very poor results. I’d always figured it was because I didn’t have anyone to practice it on, and perhaps that is exactly why?
No, its because its not a good learning app. Its a game first and foremost, not something you can learn from. You can maintain a language learned with it but not if it is actually a new language.
It is a game, and that is why people use it. They don’t want to be annoyed learning, and it’s just for fun. You seem to think that everyone should do things for the same reason.
it’s really rude to market a game as a language learning app
You need to learn NOT to read between the lines, I did not write that you cannot use it for fun or relaxation. I have done so myself several times
I can’t comment on its effectiveness, but I’ve enjoyed listening to free Language Transfer lessons. The idea being that there’s probably words you already mostly know because of shared language history.
