Sonomos wot Sonomos

Sonomos is a local-first privacy layer that detects and masks sensitive data before it leaves your device.

Built for privacy-conscious individuals and professionals who use AI tools like ChatGPT, Gemini, and Claude, Sonomos scans text inputs in real time for PII, financial data, credentials, and other secrets using on-device AI and enhanced pattern analysis. No data is sent to external servers for processing.

Core features:
- Real-time sensitive data detection with a traffic-light risk indicator (green/yellow/red) as you type
- One-click masking that replaces detected PII with realistic stand-ins before you hit send
- Monitors and blocks third-party tracking scripts from capturing your keystrokes
- Scans uploaded documents (PDF, DOCX, XLSX, images via OCR) for sensitive content before submission

All detection and masking runs entirely on your device. Sonomos never transmits, stores, or inspects the content you type. The only network requests are for account authentication and subscription status.

Designed for attorneys, accountants, compliance officers, financial advisors, and anyone handling confidential or sensitive information in AI-powered workflows.
