Clean your text before you paste it into any AI
Before you paste text into ChatGPT, Claude or Gemini, swap the sensitive values for reversible tokens like [EMAIL_1], then restore the real values in the AI’s reply. It runs entirely in your browser — nothing you paste is uploaded.
AI assistants are useful, but pasting raw emails, contracts or customer notes into them can leak names, addresses, card numbers and more into a third party’s systems. Scrub for AI swaps sensitive values for reversible tokens before you paste, then puts the real values back into the AI’s reply — so the model only ever sees placeholders.
How does it work?
Paste your text and it’s scanned for emails, phone numbers, card numbers, IBANs, UK sort codes and account numbers, BIC/SWIFT codes, postcodes, SSNs, IP addresses, API keys and IDs — plus names that appear with a title or label (“Mr …”, “Account Name: …”), masked at every occurrence. Each is replaced with a stable token like [EMAIL_1]. You copy the cleaned text into the AI; when you paste the reply back, the tokens are swapped for your real values again.
Where is the token map kept?
The link between a token and your real data is held only in the page’s memory. It is never uploaded, and it disappears when you close the tab — so nothing sensitive is stored anywhere.
Which AI assistants does it work with?
Because it just cleans and restores text, it works with ChatGPT, Claude, Gemini, Copilot or any other tool — you stay in control of what actually gets pasted.
FAQ
Does my text get sent to a server?
No. Detection and the token map both run in your browser. The only thing that leaves your device is the cleaned, tokenised text that you choose to paste into the AI yourself.
Can I get my real values back?
Yes. Paste the AI’s reply (which contains the tokens) back into the tool and it restores your original values.
What kinds of data does it detect?
Emails, phone numbers, credit-card numbers (checksum-validated), IBANs, UK sort codes and account numbers, BIC/SWIFT codes, postcodes (UK, US ZIP, EU, and more), US SSNs, IP addresses, API keys/tokens, common ID formats, and names that carry a title or label (“Mr …”, “Account Name: …”). Unlabelled names in free text and street addresses are not detected yet.
