GuardAI reads what you type into AI tools and catches sensitive details before they leave your browser. Everything runs locally, so we physically cannot see your data.
Hi, my name is Sarah Chen and my number is 0412 345 678 if you need it. Can you draft a reply?
Works on the AI tools you already use
New platforms are added as they launch
Zero external calls. Nothing is sent anywhere to be processed.
No account required. There is nothing to sign up for.
Nothing hidden. The extension is open to inspection.
One message goes in. GuardAI swaps the name, the number and the address, sends the safe version to ChatGPT, then puts your real details back into the answer.

Every message you send to ChatGPT, Claude or Gemini can be stored, used for training and kept indefinitely. Most people find out what they shared long after they sent it.
Write your message in ChatGPT, Claude or any other AI tool. Nothing about the way you work has to change.
Sensitive details are swapped for realistic stand-ins. A different name. A different number. A different address. The AI only ever receives the fake version.
When the reply comes back using the fake details, GuardAI restores your real ones first. You read the real answer. The AI never had it.
Prefer to stay in control? Three other ways to run it.
Names, phone numbers, emails, addresses, Medicare numbers, TFNs, passwords and more.
Real values are replaced with convincing stand-ins before the message leaves your browser.
Replies come back rewritten with your real details, so the protection stays invisible to you.
Highlight anything the detector missed and mask it yourself. You decide what gets protected.
GuardAI runs inside your browser. Your messages never leave your device. There are no servers processing your text, no account holding your history and no company reading your conversations. Not won't. Can't.
Yes, completely free. No account, no subscription and no hidden costs.
GuardAI uses pattern matching that runs entirely in your browser. Nothing is sent to a server to process your messages.
ChatGPT, Claude, Gemini, Copilot, Perplexity and more. We keep adding support for new platforms.
None. There is no server, no database and no analytics on your messages. The only thing stored is your local masking table, which lives on your device and can be cleared whenever you want.
Free, instant and no account needed.
