OpenCat

Web-based AI interfaces are fine, but if you're on a Mac or iPhone, you deserve something better. OpenCat is a native AI client built specifically for Mac, iOS, and iPad, delivering a noticeably smoother and faster chat experience than any browser-based alternative. Use your own API keys without logging in or sharing your data with anyone. OpenCat packs in a rich prompt library, cross-device syncing, voice chat, text-to-image generation, image chat, and real-time translation — making it a genuinely powerful AI platform that feels right at home in the Apple ecosystem.
