The approach
Meet words. Practise patterns. Revisit.
See the structure again
Practise related sentences within a group. Each group shares a review schedule, while individual examples track their own exposure.
Build a routine
Grade your answers, review when exercises become due, and resume unfinished sessions. Follow your activity with daily and overall statistics.
Read and write kana
Practise hiragana and katakana with spaced repetition. Each character card asks you to read the kana and gives you space to practise writing it; example words help connect it to vocabulary.

Built in the open
A learning project,
in more ways than one.
Psitta is developed by Antoine Lagache. Built with Flutter, it explores language learning alongside the design of a modular study engine and a documented spaced repetition model.
Version 0.2.0 adds hiragana and katakana practice, progress statistics, configurable themes and database backup and restore. Follow the release notes for the full change history.
Explore the source code →Content with provenance
Vocabulary draws on JMdict; sentences and their English translations come from Tatoeba. Source attribution is available in the app. Editorial choices and known limitations are documented.
Psitta is a vocabulary and sentence practice tool, intended to accompany other learning resources. The ordering and scheduling are design choices, not a claim of measured learning effectiveness.
