About Browser-Based LLM Chat
How to Use
- Select a Model: Choose from available models like Qwen3 or Mistral based on your needs and hardware.
- Wait for Download: On first use, the model will download (1-6GB). This is cached for future sessions.

Browser Support
WebGPU is required for GPU-accelerated inference. Chrome and Edge have the best support. A dedicated GPU with 2-8GB VRAM is recommended for optimal performance.
Security & Privacy
100% Private: All processing happens locally in your browser. No data is sent to any server.
Your conversations, prompts, and responses never leave your device. Chat history is stored only in your browser's local storage and can be cleared anytime.
Frequently Asked Questions
LLM models are large (1-6GB). On first use, the model downloads and caches in your browser. Subsequent visits will load much faster from cache. Larger models like Qwen3-8B provide better responses but require more VRAM and download time.
WebGPU is a new web standard that may not be enabled by default in all browsers. In Chrome/Edge, go to chrome://flags and enable "WebGPU". In Firefox, set "dom.webgpu.enabled" to true in about:config. Also ensure your GPU drivers are up to date.
We offer Qwen3 (0.6B and 8B variants) and Mistral 7B. Smaller models (0.6B) are faster and use less memory, while larger models (7B-8B) provide more sophisticated responses for complex tasks like coding and analysis.
No. All processing is done entirely in your browser using WebGPU. Your conversations are stored only in your browser's localStorage and never sent to any server. You can export or clear your chat history at any time.
