Haruka is a 3D AI companion with real-time voice, WebGPU accelerated local inference, and expressive Live2D motion. Connect 20+ language model providers, install it anywhere as a PWA, and let your agent pay for premium tools on its own through x402 on Robinhood Chain.
About Haruka
Haruka runs the model, the voice pipeline, and the render loop as close to you as possible. Speech recognition and synthesis happen in real time, WebGPU keeps inference on your own device, and the character reacts to touch and tone instead of waiting for a text box. When your agent needs a paid tool, x402 on Robinhood Chain lets it settle per action without a subscription or an account.
