Each word is positioned at its Optimal Recognition Point. Smart Slowing pauses naturally at sentence boundaries. Your phone becomes a place of focus instead of distraction. No willpower required. No fighting notifications. Just you and the words. IMPORT YOUR BOOKS Import any EPUB from your device. Navigate chapters. Track your reading progress. This is a real reading app for people who actually read books. READ AT YOUR PACE Adjust speed from 100 to 1000 WPM — whatever pace lets you focus completely. Start slow, build up naturally.

Synapse transforms the way you capture and connect knowledge. Every book you read, every film that moves you, every idea worth keeping — Synapse turns them into a living graph where nothing stays isolated. — CAPTURE WHAT MATTERS Add books, movies, series, journals and personal notes as sources. Write fast, think clearly. Notes link themselves through [[wikilinks]] as you type. — SEE HOW YOU THINK Your knowledge graph visualises every connection in real time. Tap any node to explore. Tap any edge to read why two ideas are connected. Drag nodes to organise your mental map the way you see the world. — DISCOVER HIDDEN CONNECTIONS Synapse AI reads your entire graph and surfaces non-obvious links between notes — the kind your conscious mind skipped. Swipe right to accept a connection and save the reason forever. — DISCOVER WHAT TO READ NEXT Open any source and let Gemini recommend a book, film and series that share its soul. Not keyword matches — deep thematic resonance. — YOUR DATA, YOUR CONTROL Everything is stored locally on your device, encrypted at rest. Export your full graph as JSON at any time. Delete your account permanently in one tap. Synapse is for readers, thinkers, and anyone who believes their best ideas come from connecting what they already know.
