Challenge

Anki was powerful but ugly and hard to use. Quizlet lacked proper spaced repetition. Students needed a modern, AI-powered alternative.

Approach

Implemented a modified SM-2 spaced repetition algorithm, integrated GPT-4 for automatic flashcard generation from pasted text or photos, and built offline-first with Hive for study sessions without internet.

Outcome

22k downloads, primarily in DACH region. Users retain 40% more material vs. traditional study methods. 4.8★ rating.
