Desktop app + Chrome extension
SafAI is a two-part system: a desktop app that runs privacy services on your device, and a Chrome extension that integrates with AI chat UIs.
Desktop app
When you launch SafAI, the desktop app starts local privacy services on your machine. These handle PII detection, tokenisation, and restoration—all before your prompt is sent to an AI provider.
Detection combines pattern matching (for structured data like emails and phone numbers), local AI-based entity detection, and other on-device analysis. Session credentials are stored securely on your device, not in the browser.
Chrome extension
The extension adds a SafAI Send control to the Claude composer. ChatGPT and Gemini are on the roadmap. It communicates with the desktop app while you chat. Keep the desktop app running during use.
Why both are required
Browser extensions cannot run the full detection stack or hold session state with the same isolation as a local desktop service. The desktop app is the trust anchor; the extension delivers the experience inside AI chat pages.
