Scrub for AI: Hide personal data and secrets

Hide emails, phone numbers, IBANs and API keys before you paste text into ChatGPT or Claude. Runs offline in your browser.

Paste into AI without pasting your private data. Scrub for AI replaces emails, phone numbers, IBANs, card numbers, API keys and passwords in your text with neat placeholders like [EMAIL_1] and [SECRET_2], before you paste it into an AI chat or any other tool. When the answer comes back, one click puts your original values back. Everything runs inside your browser. No account, no server, no network requests. HOW IT WORKS 1. Select text on any page, right-click and choose "Scrub selection and copy", or press Alt+Shift+X. You can also open the toolbar popup and paste text into it, the result appears instantly. 2. Paste the scrubbed text into your AI tool. Sensitive values are now placeholders. 3. Select the AI answer and choose "Restore placeholders in selection and copy" (Alt+Shift+Z), or paste it in the Restore tab. Your original values return. WHAT IT FINDS • Email addresses and phone numbers (international and Dutch formats) • IBAN bank accounts and payment card numbers, both checked so ordinary numbers are left alone • API keys and access tokens from common cloud and developer services, plus JWTs and Bearer tokens • Passwords and secrets in key=value text, JSON and config files, private key blocks and passwords inside URLs • IP and MAC addresses, Dutch BSN and VAT numbers, birth dates after a label • Your own terms: client names, project codenames, internal hostnames, and your own patterns for invoice or customer numbers BUILT FOR REAL WORK • Same value, same placeholder, so the AI can still follow who is who • Click a highlighted placeholder to keep a value that is not sensitive • Placeholder numbering carries over between prompts in the same session, start fresh with "New conversation" • Turn any detector on or off in Settings • Light and dark mode PRIVACY Your text never leaves your computer. The extension makes no network requests, has no analytics and no ads. It reads a page only when you ask it to. The map that lets you restore values lives in browser memory and disappears when you close the browser, unless you choose to keep it. GOOD TO KNOW Scrub for AI finds patterns, it does not understand text. It does not recognise people's names or addresses by itself, add those as custom terms. It cannot guarantee that everything sensitive is found, so always read the result before you share it.
