FAQ

Is it safe to login with my account in the app?
Yes, it is safe. There is no data transferred in the app (you can check the source). It's just a wrapper for the popular Chat AI website. If you are still unsure, you can build your own binary and use it.
I cannot open the MacOS app because developer cannot be verified. What should I do?
In the Finder on your Mac, locate the Chat AI app (do not use Launchpad). Control-click the app icon, then choose Open from the shortcut menu. Click Open. For more details, see Apple Support: https://support.apple.com/en-sg/guide/mac-help/mh40616/mac
