Duolingo Max

Duolingo Max sits at the very top of Duolingo's subscription stack, and it is the part of the product where the company's 2023 OpenAI partnership is actually visible to users. While the free app remains a lesson engine built around translation, matching and listening drills, Max is the tier where Duolingo tries to become a speaking partner. It launched in March 2023 with GPT-4-powered features in a handful of markets and has been rolled out more widely since. In my testing, the right way to think about Max is not "Duolingo plus AI" but rather "a conversation supplement bolted onto a curriculum you already follow." If you are not already using Duolingo regularly, Max is the wrong entry point. If you are, it answers the single biggest weakness of the free app: nobody to talk to.

What Max actually adds

Duolingo runs three tiers. Free Duolingo gives you the core lesson path with ads and the hearts system. Super Duolingo, at $13.99 a month or roughly $84 a year billed annually at time of writing, removes ads, gives unlimited hearts and adds personalized review (beginnersinai.org's 2026 pricing roundup, which matches what I saw in the app's upgrade screen). Max sits above Super at $29.99 a month or $168 a year, which works out to about $14 a month when billed annually — that is the number I use when comparing it to other speaking tools. There is a Max Family plan as well, at roughly $240 a year for up to six users.

What do you get for the jump from Super's $84 a year to Max's $168? Two things, and as of 2026 only two things. Video Call connects you to Lily, one of Duolingo's in-app characters, for live spoken conversation in the language you are learning. She speaks, you speak back, and the exchange is transcribed. Roleplay drops you into scripted real-world scenarios — ordering coffee, asking for directions, negotiating a rental — and afterwards you get AI-generated feedback on accuracy, complexity and vocabulary range. The third historical Max feature, Explain My Answer, which explains why a wrong answer was wrong, was moved to the free tier in January 2026 (collegehobbies.com reported the change from Duolingo's official blog; I confirmed the feature appears in a free account). That migration matters for the value math: the AI grammar explanations that once justified Max are now a free-app feature, and the two conversation features carry the whole $84-a-year premium on their own.

Language coverage is the other constraint. At time of writing, the AI conversation features work for seven languages learned from English: Spanish, French, German, Italian, Portuguese, Japanese and Korean. The free and Super tiers cover Duolingo's full catalog of 40-plus languages; Max's AI layer covers the top seven.

My testing notes

I put about three weeks into Max, split between Spanish and French, with most of my time in Video Call since that is the feature doing the heaviest lifting.

First observation: the curriculum continuity is real and it is the thing that distinguishes this from just talking to a voice chatbot. Lily's vocabulary tracked what I had actually been shown in lessons. Early on, the conversation stayed inside food, travel and family topics — the same word sets the lesson path had drilled — and follow-up questions pushed one step past what I had seen rather than jumping to abstract discussion. When I deliberately answered a Video Call prompt using a subjunctive construction I had not been taught yet, Lily kept the conversation going without derailing into a grammar lecture. Compare that with generic voice chat in Spanish, which happily talks over your level and teaches you nothing structured.

Second observation: the Roleplay feedback is accurate but shallow. After each scenario I got a short report card covering accuracy, complexity and varied vocabulary. Running the same Paris café scenario three times with deliberately sloppy answers, the accuracy score did move down and the complexity score tracked my sentence length fairly sensibly. But the feedback never told me which sentence was wrong or why. If you want "you used the indicative where the subjunctive was required," you still need a tutor or a good grammar app. For me, that caps the learning value: the practice is good, the correction is vague.

Third, on the practical side: Video Call sessions hold up well technically. Audio recognition handled my mediocre accent without repeated re-prompts, turn latency felt like a normal phone call rather than a robot exchange, and sessions run about five to eight minutes — deliberately short, which fits Duolingo's habit-loop design. Lily also remembered topics from earlier calls, which gave a faint sense of continuity. It is mobile-first; the desktop experience is the lesson app, not a calling environment.

I also ran the price-per-conversation math. At $168 a year, if you Video Call three times a week, each session costs about a dollar. That is genuinely cheap conversation practice. The catch is that the same money buys ChatGPT Voice at $20 a month (with unlimited open-ended conversation in any language) or Speak, which in my view has a stronger conversation engine for serious learners. Max wins on integration with the Duolingo curriculum and on character-driven engagement; it loses on raw conversational depth and language count.

What Max does not do

Max is not a tutor replacement and does not pretend to be one. There is no human contact, no live correction loop, no writing correction, and no exam preparation beyond the separate Duolingo English Test product. It will not get you through the intermediate plateau on its own — the scenarios are structured and repetitive by design, and free-form discussion of, say, a news article is out of reach. The AI features also stop at seven languages; if you are studying Arabic, Hindi, Dutch or any of the long-tail courses, Max buys you Super features and nothing else, which is a poor trade at this price. There is no free trial of the AI features as far as I could see beyond Duolingo's usual promotional offers, so the only way to test Video Call quality for yourself is to pay for a month. And note the platform dependency: Duolingo has already moved one Max feature down to free — the tier's value proposition can change under you mid-subscription.

Two smaller gripes from use: the character framing (Lily's deadpan persona) is charming for some learners and grating for others, and there is no way to swap in a neutral voice. And while Lily's memory of prior calls is a nice touch, it is shallow — she remembers topics, not your mistakes.

Verdict

Duolingo Max is a well-executed conversation layer for people already committed to Duolingo, with the curriculum integration as its genuine differentiator and the shallow feedback and seven-language ceiling as its real limits. I rate it 3.6, weighting core functionality depth heavily: the conversation practice works and is cheap per session (40%), the value case narrowed when Explain My Answer became free but $168 a year for unlimited AI conversation is still defensible (20%), the UX is frictionless in the good sense of short, guided sessions (20%), the ecosystem and learner community are huge though the AI feature set is thin (10%), and Duolingo is a stable public company with no reliability concerns for a subscription this size (10%). If you live in the app daily and want to start speaking, Max earns its price. If you are shopping for a speaking tool first and an app second, start elsewhere.
