Clean your text before you paste it into AI

Paste an email, document or code snippet. We swap out personal and secret details for safe labels, so you can ask AI for help without handing over your data.

Runs on your device only
Safe to paste
Your cleaned text appears here as you type.

How it works

Pattern matching runs on your device as you type. Each detail is replaced with a numbered label, for example [EMAIL 1] or [CARD 1]. Card numbers are checked with the Luhn formula, so random long numbers aren’t flagged.

  • Toggle any category off if you need it kept.
  • Add names in the "Also hide" box: names are the one thing patterns can’t reliably find.

Your privacy

This tool runs entirely in your browser. Nothing you type or paste is uploaded, stored or sent to us or anyone else. You can even disconnect from the internet after the page loads and it still works.

Questions

Why remove personal details before using ChatGPT or another chatbot?

What you type into a consumer chatbot can be stored on the company’s servers and, depending on your settings, used to improve its models. On a work account, admins may have access. Removing names, contact details and ID numbers first means a leak or review exposes nothing personal.

What does it detect?

Email addresses, phone numbers, payment card numbers (checked with the Luhn formula), US Social Security numbers, IBANs, Indian Aadhaar and PAN numbers, IP addresses, street addresses, dates of birth, API keys and passwords written as "password: …", plus links that carry login tokens. You can add your own words, such as names or company names.

Does it catch everything?

No automatic tool does. Names in particular are hard to detect reliably, so add them in the "Also hide" box and read the cleaned text before you paste it.

Can I put the details back into the chatbot’s answer?

Yes. Each item gets a numbered label like [EMAIL 1], and the same value always gets the same label, so you can swap the real details back in yourself after you get the answer.
