Skrongle Mini, a self hosted AI course generator and learning app on R. pi zero

Skrongle is a single self-hosted binary that runs on a Raspberry Pi Zero 2 W and teaches from JSON course files, offering lessons, adaptive quizzes, five-minute practice sessions, games, flashcards and an AI tutor, with Spanish and French courses included. It supports up to eight invited accounts with no e-mail or outside services except the AI provider keys the owner supplies, and courses can be hand-written, uploaded, or generated by describing them to an AI. It is licensed AGPL-3.0, and databases from before version 1.0 are not upgraded.
