Kalmatu

Learn German, Russian or Japanese, from your first word.

Kalmatu puts spaced-repetition flashcards, a beginner grammar course and an AI conversation partner in one place, so the words you study are the words you practise.

What's inside

Flashcards that schedule themselves

Every word becomes two cards, one in each direction, scheduled the way Anki schedules them. Rate each card Again, Hard, Good or Easy and it comes back just before you'd forget it.

A complete A1 grammar course

About twenty short lessons per language, each with tables, translated examples, common mistakes and exercises with hidden answers. No textbook needed.

A tutor to practise with

Practise each grammar topic with an AI tutor that corrects you, or hold a free conversation once you know ten words. New words from a conversation go straight into your flashcards.

Progress you can see

Watch your known vocabulary grow day by day, and get an estimate of which CEFR band your practised words cover.
