Most AI tools help you talk to AI more. OmniShield helps you stop leaking to AI. ChatGPT extensions organize chats or add sidebars. We mask secrets at send time — inside ChatGPT, Claude, Gemini & Cursor — before they leave your browser. On-device. No prompt upload. API keys,env dumps, JWTs, emails: gone before send. Free core masking. Pro adds OCR, healthcare patterns, block mode. Other launches give you a better assistant. We give you a seatbelt for AI.

I built OmniShield because I kept catching myself and my team mid-paste. You’re debugging at midnight. ChatGPT is open. The log has an API key. You think “I’ll delete it after”… and you hit send anyway. Same story with .env dumps, JWTs, client emails — secrets that were never meant to leave your laptop, now living in someone else’s chat history. Most “AI extensions” help you use ChatGPT more. I wanted the opposite: a seatbelt. Mask secrets at send time, inside ChatGPT, Claude, Gemini, Perplexity, and Cursor — on your device, before the request leaves the browser. No prompt upload. No “trust our server.” The process evolved a lot. I started thinking paste warnings would be enough. They’re not — people override them. Then I built local scrubbing. Better, but still manual. The breakthrough was wire-level send-time masking: protection that works even when you’re tired and careless. Free for core masking. Pro for OCR, healthcare patterns, block mode, and custom rules. If you use AI daily for code or work: try pasting a fake sk-… key into ChatGPT with OmniShield on. Watch it become a placeholder before send. That’s the whole product. Would love your feedback — especially false positives, sites we should support next, and what almost made you leak last week. — Anuj

The scariest button in tech is still “Send.”

Hey PH

I m Anuj Cyber Security Professional, currently building OmniShield.

Quick context: I ve watched Shadow AI get worse for years. Devs (and honestly, everyone) use ChatGPT/Claude for debugging, writing, life admin and then paste keys, client data, bank stuff, medical notes without thinking. Blocking AI isn t realistic. Ignoring the leak risk isn t either.

So I built a Chrome extension that masks secrets at send time on-device on ChatGPT, Claude, Gemini, Cursor, etc. Free core. No upload your prompt to us.
