Duolingo and Memrise make opposite bets on what keeps a learner going. In Duolingo vs Memrise, Duolingo is the better fit if you want a free-to-start, game-like daily routine, and Memrise is the better fit if you want to hear real native speakers in short video clips and review vocabulary with spaced repetition.
Both are hosted, closed-source apps with a free way to start, and neither can be self-hosted. What separates them is method. This guide compares lessons, vocabulary retention, speaking practice, languages and the free-to-paid model, using Enlisted's catalogue and the vendors' own pages.

Duolingo vs Memrise: what is each app betting on?
Duolingo bets on habit. Enlisted describes it as a language-learning app that turns practice into short, game-like lessons, which suits a few minutes at a time on a phone or in a browser. The vendor's site adds daily streaks and competitive leagues, the mechanics meant to bring you back tomorrow.
Memrise bets on authenticity. It presents itself as useful and personalized in contrast with heavily gamified apps, and it is aimed at people with a specific reason to learn, such as passing an exam, speaking confidently at work, building relationships or exploring a culture. Its lessons draw on video clips of native speakers and spaced repetition.
If you have tried a streak-based app before and drifted away, Memrise's pitch is aimed at you. If a streak is exactly the nudge you need, Duolingo's is.
How do the lessons differ?
Duolingo's exercises are short and varied. Its site describes a mix of vocabulary, grammar, listening, speaking and translation activities in bite-size sessions, so a typical sitting is a handful of quick tasks rather than one long lesson.
Memrise follows a sequence its homepage describes in three steps: hear a phrase in a native-speaker video, learn it through practice exercises, then copy it by recording yourself and comparing your version with the speaker's. Its migration notes describe an AI partner, MemBot, powered by OpenAI technology, that sets missions and games for spoken and written conversation, and a recommended path that adapts to your interests in place of fixed linear courses. Some of those features, such as the video lessons matched to your level, are limited to certain languages, so check yours.
The practical result is two different feels. Duolingo rewards finishing a short lesson. Memrise rewards recognizing and repeating real speech.
Which is better for remembering vocabulary?
Memrise is built more directly around retention. Its site names spaced repetition, a review schedule that brings words back as you are about to forget them, as one of its core methods, alongside the video clips that give each phrase a voice and a face.
Duolingo takes a different route. Its lessons mix exercise types, and on the paid tiers the vendor describes personalized practice built from your mistakes. That targets what you got wrong, but it is not the same thing as a dedicated review schedule that Memrise names as a core method.
If your goal is to retain a large vocabulary for an exam or a move abroad, lean toward Memrise, or pair either app with a flashcard tool such as Anki.
Which has better speaking and listening practice?
Memrise has the more distinctive listening material. Its video clips of native speakers, in the vendor's words thousands of short videos, expose you to natural speech and a range of voices, and the record-and-compare step is built into the method.
Duolingo includes speaking and listening exercises within its regular lessons. Its Max tier adds Roleplay, conversations with AI characters in scenarios such as a cafe or an airport, and Explain My Answer, a personalized grammar explanation of a mistake. Those features are on the top paid tier, not in the free version.
For conversation with a person rather than a program, neither product is the answer. A tutor marketplace such as italki covers that.
Which one covers more languages?
Memrise's homepage lists a very long range of languages. It runs from Spanish, French, Japanese and Korean to Welsh, Latin and Yoruba, and even constructed languages. If you are studying something less common, Memrise is more likely to name it.
Duolingo offers many of the most popular languages, including Spanish, French, German, Japanese and Mandarin, and Enlisted's catalogue notes many languages to choose from. Course depth varies on every app, and the course direction matters: learning Spanish from English is a different course from learning English from Spanish. Look up your exact pair on both sites.
Does either app suit a specific goal, such as a trip or a job?
Memrise is the one that frames itself around goals. Its overview describes goal-based courses for work, exams and travel, and Enlisted's catalogue lists learning conversational phrases for work or travel and studying a less common language among its use cases. If you can name the situation you are preparing for, that framing can help you stay on target.
Duolingo's catalogue entry points to daily language practice and picking up a language before a trip. It is a general-purpose habit builder more than a goal-specific course, which is fine if your aim is simply to keep going. If you need to reach a particular standard, such as an exam level, look at what each product says about it for your language rather than assuming either one covers it.
Either way, set a concrete target before you start. A target such as ordering a meal, following a short conversation or reading a menu is easier to measure than "get better".
What is the pricing model for each?
Both are freemium, so you can start without paying.
Duolingo's free version includes ads and a system that limits how many mistakes you can make before you must practice or wait. The paid tiers, Super and Max, remove ads and the mistake limit, add personalized practice on your mistakes, and at the Max level add the AI features above.
Memrise says you can start learning for free and that its paid plans unlock extra features. The detail of what is gated changes, so check its plans page. Enlisted shows plan-by-plan prices in the live section below this guide, which is the place to compare the tier you would actually buy.
Duolingo: best for a free-to-start daily routine
Duolingo is a gamified language-learning app and website built around short lessons, presented as free to start with optional paid features. It runs on the web and on phones, and its pages also list Math, Music and Chess lessons and the Duolingo English Test. See Duolingo's listing for the full entry.
- Best for: beginners and casual learners who want a free start and a routine built around streaks.
- Watch out for: the free version has ads and a mistake limit, and the lessons are not built around native-speaker video or a review schedule.
Memrise: best for native-speaker video and vocabulary review
Memrise is a language learning app that uses video clips of native speakers and spaced repetition to build practical speaking skills. It is organized around goals such as exams, work and travel, and it lists a very large range of languages. See Memrise's listing, or Memrise alternatives for more routes.
- Best for: learners with a concrete goal who want authentic speech, and people studying a less common language.
- Watch out for: it presents itself as less gamified than Duolingo, which may matter if you rely on streaks, and some features, such as video lessons matched to your level, are not available in every language.
Is there an open-source option?
Neither app can be self-hosted, and neither is open source. If your priority is spaced repetition you control, two open-source programs cover that part:
- Anki schedules flashcard reviews for when you are most likely to forget, with sync and add-ons.
- AnkiDroid is the Android port of Anki, licensed under GPL-3.0, with AnkiWeb sync, statistics and shared decks.
They are flashcard tools, not guided courses, so you bring or download the decks. See the open-source and SaaS alternatives to Memrise for the wider list.
Which should you choose, Duolingo or Memrise?
| If you want... | Pick |
|---|---|
| A streak-driven routine you can start free | Duolingo |
| AI roleplay conversations | Duolingo Max |
| Real native-speaker video clips | Memrise |
| Vocabulary review on a spaced schedule | Memrise |
| A less common language | Memrise (check yours) |
| Free, open-source flashcards you control | Anki |
If you are unsure, try Memrise's free start for a week, then Duolingo's, in the same language. Whichever one you open without being nudged is the one to keep.
