Indie dev builds handwriting-based language learning app with Claude, runs on e-ink
tokentrillionaire · reddit · 2026-11-05
A developer shared an interactive language-learning app built with Claude: learners practice by handwriting in the target language, and the app reads the writing, switches languages, generates flashcards in that script, and checks answers with corrective nudges until you get it right.
Technical highlights: powered by a Claude Code agent loop running directly on tablets, shipped as a single Rust binary across devices including e-ink; a Remarkable Paper Pro build is next. Free open beta on Google Play (Android 11+, stylus) and iPad via TestFlight. No sign-ups or accounts — your learning data stays on-device as plain files.
