Primecraft

Primecraft is a mobile AI sandbox where you explore procedurally generated worlds, train your own on-device AI, and share trained models with friends — all without cloud servers. 🌍 EXPLORE INFINITE WORLDS Travel across a grid of unique planets — grass, lava, ice, crystal and more. Each world has its own biome, gravity, and creatures. No two planets are the same. 🤖 TRAIN YOUR OWN AI • Embodied AI Companions — Train AI cubes that learn from your gameplay actions • Image Classification — Use your camera to train custom classifiers (bucket vs chair, thumbs up vs down, etc.) • Language Models — Download and run small language models directly on your device for private conversations 📡 SHARE TRAINED MODELS Share your trained classifiers with nearby devices over WiFi. Enable sharing with a 6-digit PIN, and friends can download your model to use instantly. 🔒 FULLY ON-DEVICE All AI runs locally on your phone. No internet required. No data sent to cloud servers. Your models, your device, your privacy. ✨ FEATURES • Infinite procedurally generated universe • On-device neural network training • Hugging Face model downloads • P2P model sharing over local network • Custom image classifiers with camera • Adjustable training parameters • Works offline after initial setup 🚧 EARLY ACCESS Primecraft is in active development.
