About GhostChat

GhostChat is a fully client-side AI chat application. It runs large language models directly in your browser using WebGPU and WASM, processes documents locally, and stores all data in IndexedDB. No server. No API keys. No data leaves the device.

Why local?

• Privacy-conscious professionals (lawyers, doctors, journalists)
• Developers who want offline AI
• Anyone who wants ChatGPT without the cloud
