Why Synapse
Three promises. No fine print.
Your team, in sync.
Notes, tasks, projects and meetings in one shared workspace. Every change shows up live for everyone.
Your AI never leaves your machine.
Your browser talks straight to Synapse Bridge, our small app that runs the AI on your computer. Prompts never touch our servers, and there is no cloud AI fallback.
Your data stays yours.
Stored in Montréal, locked down by row-level security, exportable as Markdown and JSON at any time.
How it works
Up and running in three steps.
1
Get your invite
Request beta access. You get an email as soon as a spot opens.
2
Bring your team
Create a workspace and send each teammate a one-time link. Owners, admins and members each get the right access.
3
Add Synapse Bridge
Optional. Once you are signed in, the Local AI page offers Synapse Bridge: it picks a model that fits your computer and runs it there. Everything else works without it.
Pricing
Free for small teams. One simple price when you grow.
Synapse is free for everyone during the private beta. This is how paid plans will work when they start.

Frequently Asked Questions
Questions, answered.
Privacy, the AI, what you need, and your data.
Have architectural questions?
Reach out and we can walk you through how it is built.
No. Synapse is an online app, so you need an internet connection to reach your workspace. The AI is the exception: it runs on your own computer with Synapse Bridge, so your prompts never leave your machine.
