The Best Free Alternatives to Duolingo

The search for free alternatives to Duolingo is not really about finding a better language app. It is about deciding whether you are learning a language or playing a game about learning one.

Duolingo’s free tier works. The bite-sized lessons, the streak counter, the leaderboard that makes you competitive with strangers — together they get millions of people to open the app every day. The problem is not that Duolingo is bad. The problem — familiar to anyone who has watched Grammarly follow the same trajectory — is that the parts that teach you a language and the parts that keep you inside the app are increasingly at odds.

The heart system limits how many mistakes you can make before the lesson stops — the same calculated friction that makes Spotify shuffle albums on its free tier. The path through each course is fixed and slow. The vocabulary you drill in the early units — the apple, the boy eats, the cat is black — can carry you through weeks of study without reaching the sentences you would actually use.

The alternatives that follow each cover a piece of what Duolingo does. None covers all of it. The right choice depends on whether you want someone else to guide you, or whether you are ready to build your own study routine with tools that are better at their one job than Duolingo is at any of its many.

Memrise: native speakers and community courses

Memrise is the closest structural match to Duolingo: a course-based app with vocabulary, audio, progress tracking and a gamified feel, all available without paying. What sets it apart is how it teaches pronunciation.

Duolingo relies on text-to-speech for most of its audio. Memrise uses Learn with Locals: short video clips of native speakers saying the word or phrase you are learning, filmed on the street or at home with natural intonation and real mouth shapes visible. For languages where pronunciation is the hardest part — French nasal vowels, Arabic consonants that do not exist in English, tonal languages like Thai or Vietnamese — seeing and hearing a real person produces a result that a synthetic voice cannot match.

The official Memrise courses are free with ads and a daily usage cap. The community courses, built by users and covering languages from Catalan to Klingon, are entirely open. The trade-off is that community courses vary in quality: some are meticulously structured with audio and example sentences, others are vocabulary lists with no context. Reading the course reviews before committing solves this.

Memrise uses spaced repetition, but it does not give you control over the algorithm. Words come back for review on a schedule the app decides. For most beginners that is enough. For anyone who wants to accelerate or slow the pace, it is a limitation.

Clozemaster: real sentences at scale

Clozemaster does one thing and it does it with more depth than any free app in the category: it shows you a sentence in your target language with one word missing, and you fill in the gap.

The sentences are real, drawn from Tatoeba, a community-built corpus of translated sentences. For Spanish, French, German and Japanese that means tens of thousands of sentences per language. For smaller languages it means at least a few thousand. All of it is free.

The mode matters because it teaches grammar by exposure rather than by explanation. When you see “Je ne ___ pas” and fill in sais, veux, peux or comprends across dozens of sentences, the negation pattern embeds itself without a grammar table. This works better at intermediate level and above. A beginner who does not yet know how French negation works will find the exercise frustrating. Someone who has finished a Duolingo course and wants to build reading speed will find it exactly right.

Clozemaster covers more than fifty languages, including many Duolingo does not — Latin, Icelandic, Ancient Greek, Occitan — and the text-only interface is deliberately sparse. No animations, no sound effects, no streak celebrations. It assumes you already want to study.

The free tier is generous: unlimited sentences in all languages, with text input for answers. The paid tier adds audio and the ability to review sentences you got wrong in bulk, both of which are conveniences rather than essentials.

Anki: spaced repetition you control

Anki is not a language app. It is a flashcard system built on spaced repetition — the idea that the best time to review something is the moment before you would forget it. You create the cards, or you download a shared deck built by someone else, and Anki shows you each card on a schedule calibrated to how well you remember it.

The power is in the control. A Duolingo lesson decides what you review and when. With Anki you decide: twenty new words a day, or fifty, or five. You decide whether to drill vocabulary, verb conjugations, kanji stroke order or whole sentences. You decide how long each review session lasts. No hearts, no ads, no gamification.

The shared deck library at ankiweb.net is the real resource. For Japanese there are decks with six thousand sentences sorted by word frequency, each with native audio. For Spanish there are decks organised by CEFR level from A1 to C2. For medical students studying Latin and Greek roots there are decks with image occlusion for anatomy diagrams. The quality varies — some decks have errors, some have no audio, some are abandoned — but the top-rated ones for major languages are polished enough to serve as a primary study tool.

Anki’s weakness is the one Duolingo solves best: it does not motivate you. The interface is functional, the learning curve to configure it is real, and no one sends you a push notification when you have not opened it in three days. You open it because you have decided to, not because a cartoon owl told you to.

Lingodeer: grammar taught, not absorbed

Lingodeer was built for Asian languages — Japanese, Korean, Chinese — and then expanded to European ones. The difference from Duolingo is visible in the first lesson: Lingodeer explains grammar.

Where Duolingo presents sentences and expects you to infer the pattern (“I go”, “he goes”, “they go” — figure out the conjugation), Lingodeer stops and tells you what is happening. A lesson on Japanese particles explains that は marks the topic, が marks the subject, and を marks the direct object, then gives you exercises that force you to choose the right one. A lesson on Korean honorifics explains the difference between casual, polite and formal speech levels before asking you to produce them.

For European languages this matters less, because the grammar is closer to English and can be absorbed through enough exposure. For languages where the word order is reversed, the verb conjugates by politeness level, or the writing system has three scripts — the explicit instruction is the difference between understanding and guessing.

Lingodeer’s free tier covers the introductory material for each language. The full courses require a subscription. For someone starting Japanese, Korean or Chinese from zero, the free lessons are enough to learn the writing system and fundamental sentence patterns before deciding whether to pay for the rest or move to Anki and Clozemaster.

What you lose by leaving Duolingo

Duolingo’s moat is not its pedagogy. It is the combination of a guided path, a streak counter that triggers loss aversion, and leagues that make you competitive with strangers. Remove those and you remove the reason many people open the app at all.

The free alternatives assume you already have the motivation. They do not celebrate when you finish a unit. They do not send a passive-aggressive notification when you have not practised in two days. For some learners that is liberation — finally, studying without the game mechanics. For others it is the reason they stop.

The honest answer is that supplementing Duolingo with one or two of these tools works better than replacing it outright. Memrise for native-speaker audio, Anki for vocabulary drilling, Clozemaster for reading practice — each does its job better than Duolingo does, and using them alongside the green owl covers more ground than any single app alone.

Frequently asked questions

What is the best free alternative to Duolingo?

Memrise, if what you want is a structured course with vocabulary, audio and a progress tracker, all free. The community-made courses cover languages Duolingo does not, and the Learn with Locals feature plays short video clips of native speakers saying the words you are studying. The free tier has ads and a daily limit on the official courses, but community courses are fully open.

Can I really learn a language for free without Duolingo?

Yes, and the combination is stronger than any single app. Anki for vocabulary drilling with spaced repetition, Clozemaster for reading real sentences in context, and YouTube or podcasts for listening comprehension. What Duolingo provides that these do not is a single guided path: with the free alternatives you have to build your own routine, but the materials are better.

Why does Duolingo limit mistakes with a heart system?

Duolingo introduced the heart system — where you lose a heart for each mistake and have to wait or pay to refill — as a way to encourage accuracy and generate subscription revenue. On the free tier you run out of hearts after five mistakes and must either practise old material to earn them back or subscribe to Super Duolingo for unlimited hearts. The free alternatives in this article do not use a heart system at all.

Which free alternative is best for Asian languages like Japanese, Korean and Chinese?

Lingodeer, because it was built specifically for Asian languages and teaches grammar explicitly. The lessons explain sentence structure, particles and honorifics instead of expecting you to absorb patterns through repetition. Anki for kanji or hanzi drilling with shared decks like Core 2k/6k for Japanese rounds out the toolkit. Clozemaster has extensive sentence banks for Japanese and Korean at intermediate level and above.

What does Duolingo do that no free alternative matches?

Two things. First, the gamification layer — streaks, leagues, chests, animations — is more polished than anything else in the category, and for people who need that external motivation to keep studying, losing it can mean stopping altogether. Second, Duolingo has a single path through each language that requires no decisions from the learner. All the free alternatives ask you to choose what to study next, and that is both their strength and their friction.
