Synap is your memory, externalized. Everything you know, carried outside your head, connected, and yours. Your mind was never meant to hold all of this. Keep a thought in Synap and it stays exactly as you wrote it, on the day you wrote it. Synap connects it to what you already kept, on its own. Nothing to file, nothing to tag. Ask for it back in your own words and the answer comes from your own entries, each one cited. Synap works with or without AI. Keeping, search and the record all run on your iPhone. Bring an assistant when you want one, or do not. Either way the record is yours, on your own device. KEEP ANYTHING, IN SECONDS Type it, say it, share it from any app, or speak it into your Apple Watch. Workouts you record with Apple Watch or any app that saves to Health land in your memory on their own, route included. FIND IT BY MEANING Search understands what you meant, not just the words you used. It runs on your phone, so it works with no signal. ASK YOUR OWN MEMORY Ask a question and get an answer drawn from your own entries, with the exact entries it came from. Use Apple Intelligence on a supported iPhone, sign in with your Claude account, or connect ChatGPT or Gemini. Your entries stay on your phone until you ask. SEE WHAT YOU MISSED Insights reads across everything you kept and shows the patterns, the contradictions and the blind spots. Reflect shows the shape of a season of your thinking. Open the whole record as a map you can move through. BRING WHAT YOU ALREADY HAVE Import your ChatGPT and Claude history and it becomes part of the record the moment it lands. ON YOUR HOME SCREEN AND YOUR WRIST Widgets for today, the record, recent entries and your body. Live Activities while something is being kept. A watch app that leads with one Speak button. PRIVATE BY DESIGN Synap is local first. Your entries, your search and your voice transcription run on your device. Cloud sync is optional and off until you turn it on. Names can be hidden before anything is sent to an AI you connect. FREE Keeping, search and the record on your phone, import of your ChatGPT, Claude and Obsidian history, new entries connected to what you already kept, and a cloud account with sync for up to 1,500 entries. PRO Chat that draws on your whole memory. Patterns, contradictions and blind spots, read for you. An evening digest of what was kept and what connected. Sync in the background, even with the app closed. No cap on what you keep. Know more. Carry less. Terms of Use: https://synap.ing/terms Privacy Policy: https://synap.ing/privacy
