The Problem
Your sensitive data is exposed
Sensitive data flows into AI systems every day—without oversight, controls, or visibility. The exposure is measurable.
The solution
A privacy layer for AI
Sonomos operates entirely within your browser. Before any prompt or attachment is sent to an AI service, Sonomos:
Detects sensitive data in real time
Masks protected elements while preserving semantic structure
Detecting sensitive data...
Prevents third-party scripts from capturing typed content
addEventListener('keydown')Blockedclipboard.readText()Blockedinput.value (polling)BlockedonPaste overrideBlockedLocal LLM firewall proxy (Desktop — coming soon)
What Changes
Your prompt, protected
Sonomos detects and replaces sensitive data before it leaves your browser. The AI sees tokens — never the real thing.
