Sonomos is a browser extension that protects sensitive information when using AI assistants like ChatGPT, Claude, Gemini, and Grok. It runs entirely in your browser — no servers, no network calls, no data leaving your machine.
How It Works
Dagger (Detection) — Real-time detection of sensitive data as you type. Underlines flagged content with color-coded risk levels.
Cloak (Protection) — Transforms sensitive data before it reaches AI systems using obfuscation and tokenization while preserving meaning.
Traffic Light Widget — Visual indicator showing current protection status: green (safe), yellow (review), red (high risk).
