Your personal study library — on your phone.
Drop in PDFs, docs, and notes. Search by meaning, not just words. Tap any document for an AI summary, explanation, or quiz — without your library ever leaving your device.
What it does
📚
Personal library
PDFs, DOCX, and text files organized by shelves and tags. Everything stays on your phone.
🔎
Search by meaning
Ask "where did I read about photosynthesis" — find the right pages even without exact words.
✨
AI when you need it
Summarize, explain, quiz, and answer questions from your own library — powered by Google Gemini.
🎯
Built for studying
Spaced-repetition recommendations and weak-area tracking help you remember what you read.
Privacy you can actually verify
- Your documents are stored only on your device
- AI features send only the text you tap to summarize/explain — never the full library
- Mark any document as Private to exclude it from all cloud features
- Turn off cloud AI entirely — search and library still work offline
