Your second brain,on every device.
Synapse is a Notion and Obsidian inspired note-taking app. Block editing, pages nested as deep as you need, and local-first storage that syncs when you're back online.
const page = await local.save(block) // SQLite first if (online) sync.push(page.id) // then the cloud
Everything is a block.
Headings, lists, to-dos, code and more on a rich text editor. Type markdown, hit a shortcut, or press / and pick a block.
- Highlights from chapter 3
- Questions to revisit
SELECT * FROM pages;Pages inside pages, as deep as you need.
Organize the way you think. Every page can hold more pages, and routing follows the hierarchy so every level has its own address.
Hands stay on the keys.
One shortcut to create, jump, move and sync. Fast enough that the mouse becomes optional.
The network is optional.
Everything lives locally in SQLite, so Synapse works fully offline. Keep writing on a plane or a train. When you reconnect, it syncs.
Native on desktop. Right there on your phone.
A lightweight desktop app built on Tauri instead of a heavy browser shell, and a mobile companion with the same structure.
Lightweight desktop
Built on Tauri for a native shell that stays small and quick to open.
Mobile companion
The same pages and hierarchy, in your pocket.
One workspace
Edit on one device and pick up where you left off on the other.
Under the hood.
For engineers and recruiters. Two native clients, each with a local database, meeting in one sync layer. Billing for both platforms runs through shared webhooks.
Coming soon.
Synapse is in development for macOS, Windows, iOS and Android. Want to talk about it, or about building something together?
