Japanese verb conjugation driller that pulls vocabulary from your Anki decks via AnkiConnect. Verbs are detected automatically with morphological analysis, and conjugation practice is scheduled using FSRS spaced repetition.
- Sync — connects to your local Anki instance, fetches cards matching configurable queries, identifies verbs via lindera (IPADIC), and stores them in PostgreSQL.
- Drill — pick conjugation forms (grouped by Genki textbook order) and formality levels, then type conjugated forms. Answers are validated against jp_inflections.
- Review — correct/incorrect ratings feed FSRS to schedule future reviews. Stats track accuracy per form and surface weak verbs.

Map your Anki decks to the fields conjanki needs:
[[deck]]
name = "Kaishi 1.5k"
query = 'deck:"Kaishi 1.5k" is:review'
[deck.fields]
word = "Word" # field containing the Japanese word
reading = "Word Reading" # field with kana reading
meaning = "Word Meaning" # field with English meaningAdd as many [[deck]] blocks as you like. The query uses Anki's search syntax — is:review limits to cards you've already studied.
