aidekin is an open-source AI chat assistant you add to any site with one script tag. It runs a ~1.7B model fully in the visitor's browser on WebGPU (on bitgpu, a 1-bit inference engine), so there is no backend and no API keys, and no per-message cost because the visitor's own device does the inference, which is also why nothing they type ever leaves it. Answers are grounded in a knowledge file you provide.
