The AI web apps, in a pane, with the same isolation as the CLIs.
Sometimes the tool you pay for lives in a browser, not a terminal. Muster embeds a native web view for AI web apps, keeps a per-project catalogue of them, and gives each profile its own isolated session — the web counterpart of profile isolation. macOS only.
A pane, not another browser window
AI web apps open inside Muster, in a pane next to your tasks and terminals — a native WebKit view embedded in the window, not an Electron shell and not a link that throws you out to your default browser.
Each project keeps its own catalogue of the AI web apps you use for it, so the right app is one click from the work that needs it.
Per-profile web sessions, like the CLI logins
Every profile gets its own WKWebsiteDataStore — its own cookies, storage and sessions, keyed by a stable identifier derived from the profile id. The employer’s AI web account and yours stay logged in side by side, exactly like the CLI credentials do.
Opt out per app when you don’t want isolation for one of them.
macOS only, stated up front
This surface is built on WebKit’s data-store API and ships on macOS only. On Linux and Windows the CLI side of profiles works identically; the in-pane browser simply isn’t there.
More in safety & control.
