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 โ€” 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 โ€” 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 โ€” 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 โ€” not the internet. IMPORT YOUR KINDLE HIGHLIGHTS Upload My Clippings.txt and your entire Kindle library arrives instantly โ€” 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.
