It highlights as you type
Write a prompt on ChatGPT, Claude, Gemini or any other supported site and Datablur AI scans the text right there in the box, underlining emails, phone numbers, API keys, card numbers and other sensitive values. The scan runs entirely inside your browser — nothing you type is ever sent anywhere.
- 02
You choose what happens on send
Warn before send pauses and asks (the default). Auto-redact masks everything automatically, with one-click Undo. Highlight only never blocks or alters a send. Switch mode any time from the extension popup.
- 03
Only where it's needed
It covers ChatGPT, Claude, Gemini, Copilot, Mistral, Grok, Poe and DeepSeek — and asks your browser for access to those nine and nothing else, so there is no other page it could read. Turn it off for any one of them from the popup.
Everything runs in your browser. Read the privacy policy
