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.

The Dynamic Island now carries your record: the last thing you kept, how many today, and where the day's seal stands, with Keep, Speak and Ask one press away. Speak starts listening at once and keeps the words from the Lock Screen.
Once a day your record is sealed into Bitcoin, and now you can watch it happen: sent, then written, with the block number and the proof.
Four new widgets: Patterns, Across time, Agents, and Waiting on you. Five Control Center controls, and the terminal, Patterns and Agents one tap from the home screen.
The terminal's keys now follow what is on the screen: your own commands at a prompt, the right answers when something asks, the right keys inside vim or Claude Code.
Documents you ask for come out in Synap's hand. Every model call leaves a receipt in your ledger.
Minor fixes and improvements throughout.
