Been frustrated for a while that every note-taking app is great at storing what you read but none of them connect anything.

After going through a bunch of books I had no idea what ideas they had in common, where authors contradicted each other, nothing. Obsidian gets close but the setup is a lot for most people.

Built something that does the connecting part automatically. Add highlights from any book (photo, voice, Kindle import) and it finds relationships across everything you've saved. Graph builds itself.

Stack is React Native + Supabase + Claude API for the connection engine, OpenAI Whisper for voice transcription and GPT-4o Vision for OCR, and Google Books API for book autocomplete when you add a new book.
