for your desktop
Your AI context management workspace — natively on your machine. Faster, offline-capable, and always within reach of a single shortcut.
Built for how developers work
The Contextium desktop app is not just a wrapper. It is a native experience optimised for speed, focus, and deep OS integration.
Works Offline
Your context libraries are cached locally. Browse, read, and edit without an internet connection — changes sync the moment you reconnect.
System Notifications
Get notified when teammates update shared libraries or when an AI workflow completes — without keeping a browser tab open.
Global Keyboard Shortcuts
Open Contextium from anywhere with a single shortcut. Jump to any library, file, or AI chat without leaving your current flow.
Automatic Updates
The app keeps itself up to date silently in the background. You are always on the latest version with zero manual maintenance.
Secure Local Storage
Credentials and cached data live in your OS keychain and user directory — never in a browser profile shared across sites.
