What is CrokyLingo?
CrokyLingo is a vocabulary-first language learning app that helps you build real fluency from the ground up — the same way children naturally acquire language. Start with the most common words, get comfortable with them through flashcards, audio, and stories, and let grammar follow naturally once the vocabulary feels familiar.
We support seven languages (Italian, Spanish, Dutch, German, French, Chinese, and Polish), covering CEFR levels from A1 all the way to C1. Over 3,500 carefully selected words, all organised by level and topic, with spaced-repetition practice, AI-generated stories built from your own word list, audio pronunciation, and grammar exercises.
And it's completely free. No subscription, no premium tier, no trial period. Free forever — because access to language learning tools shouldn't depend on your budget.
Research shows that knowing the 2,000 most common words in a language lets you understand over 90% of everyday conversation. CrokyLingo builds your vocabulary in exactly that order — A1 to C1, word by meaningful word — so every study session moves you forward on a clear, structured path.
Why we built it
Language apps charge €10–20 per month and hide core features behind paywalls. We think that's wrong. CrokyLingo gives you the full experience at zero cost, forever.
No investors, no growth targets, no engagement metrics to chase. We don't guilt you with streaks or scary push notifications. Croky the frog is just happy you showed up — even if it's been a week.
Everything in CrokyLingo — the word order, the story generator, the grammar exercises — is designed around how people actually acquire language, not what keeps them coming back to hit a daily goal.
