Frequently Asked Questions
Does this chat tool send my prompts to an AI server like OpenAI or Anthropic?
No. All inference executes 100% locally inside your browser tab. Zero prompts or responses are ever uploaded or transmitted to any server.
What browser engines are supported?
The default Nano-LLM engine runs in every modern browser. If you use Chrome 128+ with the Prompt API enabled, you can switch to on-device Gemini Nano, or load quantized ONNX neural weights with Transformers.js.
