The Verdict
OpenCat is a polished Apple-native chat client, and its cross-device iCloud sync is a genuine advantage if you use AI on iPhone and iPad too. But on Mac, Chapeta is far more capable - 9 built-in tools, agent mode, and a skills system turn it from a chat app into a productivity tool that can actually execute tasks on your machine. If Mac is your primary device, Chapeta delivers significantly more value.
