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.
