An Intelligent Language
Learning Platform
Your system of record for every conversation, word, and lesson — all linked in one place. Conversation, vocabulary, grammar, and writing tools that track your progress in your target language. Ten languages available. Built by a computational linguist.

Privacy-first. No ads. No tracking cookies.
Built by a Linguist, Not a Game Studio
Most apps gamify learning with streaks and points. Allomorpheus takes a structural approach — understand how a language works, and you can generate infinite expressions. No gamification. Just tools that work.

Anki, Built In
Anki language learning, native to the platform — no scripts, no add-ons, no manual cards.
Every word and phrase you encounter — in conversation, lyrics, articles, or grammar lessons — becomes a one-click Anki flashcard. Your AI tutor generates the cards; you study them in the spaced-repetition system you already use.
Generate
Create Anki flashcards from any source — conversations, lyrics, articles, or your own vocabulary lists.
Export
One-click Anki deck export in standard format. Curated collections, ready to import. No formatting headaches.
Review
Keep your existing spaced-repetition workflow. Bring the content with you — no manual card creation.
The best way to use Anki for language learning: stop building cards by hand.
