Agentic Anki

A language coach that turns your goals into Anki decks you can actually read.

Tell the coach why you’re learning Spanish and how much time you have. It proposes a curriculum built from the most common words, and once you approve it, decks build in the background, ready to import into Anki.

Every card teaches exactly one new word, in a sentence where every other word is one you already know. That rule is enforced by a validator rather than a prompt: sentences that break it go back to Claude to rewrite. Each word also gets a keyword mnemonic (an English sound-alike woven into an absurd illustrated scene), native-speaker audio and a link to real clips of it in use.

• Chat-driven agent loop: the coach plans the curriculum, then revises cards on request, re-validating every edit before it applies.
• Runs entirely in the browser: no server and no accounts. You bring your own API keys, which only ever go to Anthropic and OpenAI.
• Builds real .apkg files client-side with SQLite compiled to WebAssembly, verified by importing them with Anki’s own library.
• Cards are written in parallel batches that share a cached prompt, cutting repeat input cost.
