Built it in Swift/SwiftUI, just for myself initially. Right now you have to manually grab your sessionKey from browser DevTools, which is annoying but works. Stores it in macOS Keychain so it's secure.
Been actively working on it, already at v1.3.0 with much better UX now.
It's open source (MIT) and works with all Claude platforms (web/CLI/desktop/mobile) since they share the quota. Currently macOS only.
Curious if anyone has ideas for auto-extracting auth tokens without browser extensions.
