How it works
Six folders. Everything has a home.
Synapt keeps your whole thinking life in one place — your days, your projects, the people you meet, the things you're learning. When everything lives together instead of scattered across apps, you stop losing notes and start seeing connections.
Inbox
Catch everything. Sort it later.
Daily
One page per day — plans, scraps, journal.
Projects
Work with a finish line.
Areas
Things you keep up: health, team, money.
Resources
People, topics, reading notes.
Archive
Done, but never lost.
Why one place beats five apps
Capture anywhere, find it everywhere
Jot a thought on your phone in the checkout line. When you sit down at your laptop, it's already there — synced, searchable, and filed. One login carries your whole workspace to every device.
Your notes start talking to each other
Mention a person or a project and Synapt links it automatically. Open someone's page and see every meeting, promise and project that touches them — the context that normally hides in a dozen separate apps.
AI that actually knows your work
Because Synapt is your single source of truth, the assistant answers from your real notes — your words, your decisions, your history — instead of generic guesses. It can even write into your notes for you.
What that looks like day to day
Real asks, real answers — because the assistant can see your whole vault, not just one note.
You: "Prep me for my 1:1 with Maya"
It reads every note that mentions Maya — meetings, promises, tasks — and builds the agenda before you walk in.
You: "Summarize my week"
Your daily notes turn into an honest weekly review without you writing a word.
You: "Where did we land on pricing?"
Six months from now, ask and get the decision, the date and the why — not a scroll through old chats.
You: "File my inbox"
Capture stays fast — dump everything in the Inbox — and the sorting happens when you're ready.
Pro
Plug in the AI you already use
On Pro, you can connect ChatGPT, Claude and other tools that support connected apps. Once connected, the tool signs in to your account with your permission and gets the same abilities as the built-in assistant: search your notes, read them, and add to them.
- 1Open Settings and choose a tool to connect.
- 2Sign in once from ChatGPT or Claude and grant access.
- 3Ask it anything — it works from your notes, not from memory.
Your vault stays yours: every connection is scoped to a single account, nothing is shared between users, and since notes are plain markdown you can export everything and leave anytime.

You, in ChatGPT: "Search my notes for what we decided about the pricing page."
