Pick the platform you’ll use most. On desktop and the web, SecBrain is the same full product: capture, search, AI, sync, knowledge graph. Pick more than one if you’d like; they sync to each other.
For your Mac or PC
The full product, native; signed and notarised on macOS. Built on Tauri v2 and Rust. Fast, small and light on memory. Works offline once you’ve signed in; AI runs in the cloud through our server, with nothing to install.
The full product in your browser. Install it as a Progressive Web App to get an icon on your dock, with the same offline storage, sync and interface. Best when you want SecBrain on a machine you don’t own.
Works in current versions of Chrome, Edge, Safari and Firefox.
Save the article you’re reading with one keystroke. Capture screenshots of the page you’re on. Search your library from the extension’s side panel without opening the app. Works alongside any of the other platforms, not as a substitute for them.

Manifest V3. No analytics. The extension only talks to your own SecBrain account.
Native, written in Swift 6 and SwiftUI. Captures from any iOS app via the share sheet. Voice notes are transcribed with Apple’s speech recognition. Offline keyword search via FTS5. Submitted to the App Store; some desktop and web features aren’t on iOS yet.

Native Android is under consideration. We won’t ship a half-baked Android port. If you want to be told when it’s ready, leave us your email. We’ll send one message and never another.
macOS builds are signed and notarised by Apple. Windows builds aren’t code-signed yet, so Windows may warn you before it runs the installer.
Yes. The web and desktop apps ask you to sign in or create a free account first; the Free plan needs no card. After that, capture, search, edit and review work offline, and your library syncs across your devices. Account creation happens inside the app, not on this page.
Free to install. Your data is exportable on every plan.
