XynergiGuard
Stop sensitive data from leaving your team's AI chats.
A free browser extension that watches every prompt your team types into ChatGPT, Claude, Gemini, and others — and warns before something it shouldn't leaves the building.
Catches leaks before they happen
Detects credit-card numbers, social security numbers, API keys, internal codenames, and anything you tell it to watch for. Block or warn — your call.
Works on every major LLM site
ChatGPT, Claude.ai, Gemini, Copilot, and Perplexity — out of the box. We add new sites as they emerge.
Free, forever
The extension itself doesn't cost anything. Pair it with XynergiControl (free up to 10 devices) for centralised rules and event history.
