For the ChatGPT desktop app on Mac. Give its ChatGPT and Codex modes their own colors, so you can tell them apart at a glance.
BEFORE YOU START
ModeMark needs to recognize a window’s mode before adding color. Keep ChatGPT’s sidebar open during setup. Updates to ChatGPT can sometimes affect detection; contact us if a window stops being marked.
GET STARTED
ModeMark’s controls live in your Mac’s menu bar. Its GPT and Codex tabs let you choose separate settings for the two modes inside the ChatGPT desktop app.
Choose a mode, turn on Enabled, then pick Top Bar or Border and your preferred color. Turn on Launch at login if you want ModeMark to start when you sign in.
Need help installing ModeMark or getting it to recognize your windows? Contact us for setup help. Installation and startup instructions are being finalized.
MAKE IT YOURS
Inside the ChatGPT desktop app, use blue for Codex mode, green for GPT mode, or choose something entirely your own.

Indicators let clicks pass through and never take keyboard focus. Use Launch at login if you want ModeMark ready when you sign in.
TROUBLESHOOTING
No. ModeMark works only with the ChatGPT desktop app on Mac. Its GPT and Codex controls mark modes inside that application. ChatGPT in a web browser, the standalone Codex app, and other Mac apps are outside its supported scope.
Dialogs and windows whose mode cannot be identified stay unmarked. If your main ChatGPT window still has no color, get in touch.
Check that ModeMark is enabled in System Settings’ Accessibility permission list. Then quit ModeMark and reopen it from Applications.
If it still asks for permission, contact us so we can help you resolve it.
Yes. Once ModeMark recognizes a window’s mode, it keeps that color when you close the sidebar. A new window or a window reopened after quitting ChatGPT needs to be recognized again, so open its sidebar if the indicator is missing.
Yes. The Codex and GPT tabs have independent controls. Enable only the mode you want to mark, or enable both and choose a different color and style for each.
ModeMark runs quietly in the menu bar while it marks your windows. You can close its controls and keep working. Turn on Launch at login if you want it to start automatically when you sign in.
To hide a mode’s indicator, select its tab and turn off Enabled. Choose Quit to stop ModeMark completely.
To uninstall, turn off Launch at login, quit ModeMark, and move it from Applications to Trash. You can also remove its Accessibility permission in System Settings.
