Stop letting your reading disappear. You finish a book, feel changed by it, and three weeks later can't remember a single idea. Synapse fixes that. READING SESSIONS Open any book and start a session. Synapse tracks your reading time while you capture highlights — scan a page, type a quote, or read it aloud and let AI transcribe it instantly. When you finish, see exactly how long you read, what you captured, and whether Synapse found a new connection during that session. FLASH INSIGHTS When two highlights from different books share an unexpected idea, Synapse surfaces it automatically. Powered by Claude, the connections go beyond the obvious — finding threads across books you read years apart that you never would have noticed yourself. THREE WAYS TO CAPTURE Scan physical pages with your camera. Type or paste quotes directly. Or hold the mic and read a passage aloud — Whisper transcribes it and shows you the text to confirm. However you read, capturing a highlight takes seconds. CHAT WITH YOUR LIBRARY Ask your entire collection a question. "What do my books say about focus?" "Find a quote I saved about habits." Every answer comes from your own highlights — not the internet. IMPORT YOUR KINDLE HIGHLIGHTS Upload My Clippings.txt and your entire Kindle library arrives instantly — with covers, metadata, and connection checks running automatically. WHO IS THIS FOR? Non-fiction readers who want their highlights to actually do something. People who finish books and want to remember them. Anyone building a reading habit who wants to see it grow. Download Synapse and make everything you read count.

Open any book, tap "Start Reading Session," and Synapse quietly tracks how long you read. When you're done, tap End — you'll see a summary showing exactly how long you read, how many highlights you captured, and whether Synapse found a new connection during that session. Sessions give you a record of every time you sat down with a book. Open the Sessions tab on any book to see your full reading history for it — date, duration, highlights captured, and connections found. Three ways to capture highlights We've rebuilt how you capture highlights. Tap "Capture Highlight" on any book page and choose how you want to save it: Text — type or paste a highlight directly. Fastest for quotes you're already looking at on a screen. Scan — the existing camera flow. Point at a page, select the paragraphs you want, and the text is cleaned up automatically. Voice — new. Hold the microphone button and read the highlight aloud. Powered by Whisper, it transcribes your voice accurately and shows you the text to review before saving. Hands-free highlighting while reading on the couch. All three methods work with or without an active reading session. Smarter connections Flash Insights are now significantly more surprising. The connection engine has been upgraded and now considers both your most closely related highlights and a selection of random highlights from across your library — so connections come from places you wouldn't expect, not just the obvious ones. Reading stats in your profile Open your Profile from the Library screen to see your reading stats — total reading time, current streak, highlights captured, and books read. Everything you need to see how your reading habit is building. Kindle import improvements Uploading My Clippings.txt now correctly fetches cover images and book details for every imported book. Libraries with more than 100 highlights process in the background so the app stays responsive during large imports. After a Kindle import, Synapse now automatically runs a connection check across your new highlights so Flash Insights appear immediately. Book search improvements Search now runs two passes simultaneously — a title-focused search and a broad relevance search — so partial queries like "atomic" find Atomic Habits immediately without typing the full name. Academic papers, journals, textbooks, and publisher stubs are filtered out aggressively. You now see 7 high-quality results instead of 20 mixed ones. Bug fixes and improvements — Session summary card now correctly shows connections found during a session — Kindle upload now triggers connection checks across imported highlights — Highlight source tracking added so you can see whether you prefer scanning, typing, or voice — Fixed cover images showing wrong books for genre-seeded library books during onboarding — General performance improvements throughout
