Repetium

I'm building a language-learning app that combines AI-generated practice with spaced repetition.

The story so far

In 2021 I built a flashcard app for fun. Learning about AI later that year gave me the idea behind Repetium: generated language practice, combined with spaced repetition. The original experiment.

I made Repetium’s first commit in January 2025. It mostly slept until June 2026. Since July, I’ve been putting more energy into it. Side projects don’t build themselves, apparently.

Since July, I've been putting more time into it, mostly into the Application Foundation it runs on.

First, the groundwork

Most of my Repetium work since July has gone into the Application Foundation. It handles accounts, permissions, and billing. Those basics will support the language-learning features.
