Write badly. Learn fast. Language Diary turns imperfect diary entries into personal language lessons.
Most language apps teach you sentences about other people's lives. Language Diary works with yours: you write a few lines about your real day in the language you are learning, and AI turns exactly those lines into corrections, explanations, and review material made only for you.
**Write with what you know.**
Do not know a word? Just write it in your own language. "I go to okul today" is a perfectly fine entry. Language Diary understands what you meant, detects the mixed-in words, and teaches you the right ones.
**Get corrected, kindly.**
Every entry comes back as a natural corrected version plus a short explanation of each meaningful mistake, written in YOUR language. Tense slips, missing articles, word order: you see what changed and why, without judgment.
**Learn words from your own life.**
The app extracts the vocabulary that actually matters to you: your work, your family, your hobbies, your daily routine. No random word lists.
**Review with smart flashcards.**
Corrections and new words become spaced-repetition review cards built from your own writing. A few minutes of review a day locks in what you learned.
**See your patterns.**
Language Diary tracks the mistakes you repeat across entries and shows your progress over time, so you always know what to work on next.
**20 languages.**
Learn English, Spanish, French, German, Italian, Portuguese, Turkish, Russian, Japanese, Korean, Chinese, Arabic, Hindi, Dutch, Polish, Swedish, Ukrainian, Vietnamese, Thai, or Indonesian, with explanations in any of them.
**Private by design.**
Your diary lives on your device. Entries are sent securely to our server only for the moment of analysis and are never stored there. No account, no ads, no tracking.
**Free to start.**
Write and analyze 3 entries every week for free, with full corrections, explanations, review cards, and progress tracking. Premium unlocks up to 10 entries every day and full diary export, with a 7-day free trial on the yearly plan.
Start writing about your life today. Your mistakes become your lessons.
