Why Are People Leaving Duolingo? What Actually Changed
If you’ve searched this, you’ve probably seen the posts: people deleting the app, screenshots of the owl doing something people found tone-deaf, comment sections calling for a boycott. It’s a real backlash, not an internet rumour — but it’s also not the whole picture, and the two halves rarely appear in the same article.
Here’s what actually happened, what it means if you’re using Duolingo for German, and what to make of the fact that the company’s own numbers don’t show the collapse the headlines imply.
What actually started this
In April 2025, Duolingo’s CEO sent an internal memo announcing the company would become “AI-first” — replacing some contract translators and content creators with AI-generated material, and treating AI fluency as a factor in hiring and promotion going forward.
The memo leaked, and the reaction was immediate. Duolingo was already sitting on a large, engaged social media following built around its unhinged-owl marketing — a following that turned on the brand fast once “AI-first” started circulating as a headline rather than a memo. The company’s stock, which had peaked above $540 in May 2025, had fallen by roughly 80% by April 2026.
That’s the part everyone saw. It’s also not the only thing going on.
Three separate problems, usually lumped into one
People say “everyone hates Duolingo now” as if it’s a single issue. It’s actually three, and they matter differently depending on why you’re using the app.
1. The AI-first announcement. A brand and trust problem. It made a company known for a very human, very silly voice suddenly sound like every other company doing AI layoffs, and its most online users noticed.
2. The Energy system. A gameplay problem. Duolingo replaced its old Hearts (lose one, wait or pay) with Energy, spent on exercises rather than mistakes — which changed the app’s pacing and frustrated long-time users used to the old rhythm. This is the complaint you’ll see from people who don’t care at all about AI policy and just want their streak mechanic back.
3. Softer 2026 guidance. A business problem, relevant mostly to investors — Duolingo trimmed its growth outlook for 2026, which is part of why the stock kept sliding even as user numbers stabilised.
If you’re learning German, only the second one touches your actual experience with the app. The other two are brand and market stories.
Where things actually stand
Here’s the part most “Duolingo is dying” posts leave out.
In Q4 2025, Duolingo reported its first-ever sequential drop in monthly active users — down roughly 2 million, to about 133 million. That’s real, and it’s the number that fuelled a lot of the “everyone’s leaving” narrative.
Then in Q1 2026, daily active users grew 21%, paid subscribers grew 21%, and revenue grew 27%.
Those two things are both true at the same time. A company can lose casual users, generate a genuine PR crisis, and still be growing its core paying base. That’s roughly what the data shows — not a collapse, and not nothing either.
So should you leave Duolingo?
Depends entirely on why you’re there, and this is the question worth actually answering.
If you’re using it for vocabulary and daily habit, the backlash barely touches you. The core product — spaced repetition, streaks, bite-sized lessons — hasn’t materially changed for German learners, Energy pacing aside.
If you’re frustrated by the Energy system specifically, that’s a real, current complaint and a legitimate reason to look elsewhere — but it’s a UX gripe, not evidence the app stopped working.
If you’re leaving because of the AI-first news on principle, that’s a values decision, and only you can make it. No amount of user-growth data changes what the memo said.
If you’re leaving because Duolingo isn’t getting you to speak German, that complaint predates this entire story by years, and it’s the one worth taking seriously — because it’s structural, not a PR event.
The complaint that outlasts the news cycle
Long before anyone had heard of the AI-first memo, the most common frustration with Duolingo was some version of: I’ve done a 300-day streak and I still can’t hold a conversation.
That’s not a bug caused by recent changes. It’s how the format works. Duolingo is built almost entirely around recognition — picking the right word, filling a blank, matching a translation. Recognition is real learning, and it builds the vocabulary and pattern-sense that speaking eventually draws on. But recognising der Termin on a screen and producing it, correctly declined, in the middle of a sentence you’re inventing on the spot under mild social pressure — those are different skills, trained in different ways.
This is true regardless of what’s happening with Duolingo’s stock price or its social media reputation this month. It was true in 2023 and it’ll be true whenever the current news cycle is forgotten.
If speaking is the actual goal, that’s a format problem, not a Duolingo problem — any app built around tapping has the same ceiling. SipLingo is built the other way round: you have real voice conversations with an AI partner from the first lesson, get corrected in your own language, and get scored on word accuracy, grammar, fluency and intonation.

What Duolingo is still genuinely good at
Worth saying plainly, because a fair comparison should hold up under scrutiny: Duolingo remains excellent at the thing it was built for. Nothing gets more people to open a language app every single day. Its vocabulary coverage is broad, its spaced repetition is well engineered, and for pure habit formation it has few real competitors.
If your German goal is “read signs, follow simple conversations, build a foundation before something more structured,” Duolingo does that job well, backlash or no backlash.
What to actually watch for going forward
Not whether people are angry on social media this month — that changes weekly and tells you little. Watch two things instead:
Whether the Energy system settles. Gameplay changes usually get tuned after the initial backlash. If pacing complaints are still loud in a few months, that’s a signal the change didn’t land.
Whether AI-generated content quality holds up. The “AI-first” shift means more course content is machine-generated. Whether that content stays accurate and well-calibrated for a language as grammatically fussy as German is genuinely worth watching, independent of the PR story.

Frequently asked questions
Why are people leaving Duolingo in 2026? Mainly three things: an “AI-first” internal memo that leaked in April 2025 and damaged trust with its social-media audience, a gameplay change from Hearts to an Energy system that frustrated long-time users, and softer 2026 growth guidance that spooked investors. Company-wide user numbers dipped slightly in Q4 2025 but grew again in Q1 2026.
Is Duolingo actually declining? Not by the numbers. Q4 2025 saw a small drop in monthly active users, but Q1 2026 showed daily active users, paid subscribers and revenue all growing by 20%+ year over year. The backlash is real; a business collapse is not what the data shows.
Is there a better alternative to Duolingo for German? Depends on your goal. For raw vocabulary and habit, Duolingo remains hard to beat. For speaking practice specifically, apps built around voice conversation rather than tapping exercises — SipLingo among them — address a gap Duolingo has always had, backlash aside.
Should I quit Duolingo? Only you can weigh the AI-first decision on principle. On pure usefulness: if it’s building your vocabulary and you’re motivated by the streak, there’s no functional reason to stop. If you’ve plateaued and can’t speak despite a long streak, that’s a real limitation worth addressing — with speaking practice, not necessarily a different app for vocabulary.
Where SipLingo fits: not a Duolingo replacement for vocabulary — a complement for the part Duolingo was never built to do. Real voice conversations, corrections in your own language, scoring on four skills. Start free →
