Grant Screen Recording permission
- System Settings → Privacy & Security → Screen & System Audio Recording.
- Toggle ScreenGPT on, then relaunch when prompted.
- While you're there, also enable Accessibility for ScreenGPT — needed to detect your hover into the corner zone.
Why these permissions? ScreenGPT reads the pixels under your cursor to answer questions about what's on your screen. Nothing is saved or sent anywhere except to the AI provider you choose.
