Hey Product Hunt! 👋 I'm William, a developer based in Lima, Peru. I built CATAI because I wanted a desktop companion that was fun, beautiful, and actually useful — not just another AI chatbot. Here's what makes CATAI different: 🐱 It's a virtual pet, not a chat window. Pixel art cats walk along your macOS dock with 368 hand-drawn sprites. They meow randomly, eat, sleep, and get angry. Click one to chat. 🔒 Your conversations stay on your machine. CATAI connects to Ollama running locally — no cloud, no API keys, no data leaving your computer. 🎨 Everything is pixel art — the cats, the chat bubbles, the settings panel. It feels like a Game Boy app living on your Mac. ⚡ The entire app is ONE Swift file (~1500 lines). No Xcode project, no CocoaPods, no package manager. Just compile and run. 🌍 Trilingual — switch between French, English, and Spanish with flag buttons. Each of the 6 cats has a distinct personality powered by its own system prompt: Citrouille tells jokes, Ombre asks philosophical questions, Einstein shares science facts, Indiana tells adventure stories... I'd love to hear which cat personality you'd want to add! Try it: https://github.com/wil-pe/CATAI
