Hide personal data before you ask an AI
Swap names, emails and account numbers for placeholders before pasting into ChatGPT or Claude, then put them back in the answer.
AI chats are great at rewriting a client email or summarising a contract, but everything you paste is sent to the AI company. Names, phone numbers, IBANs and ID numbers in that text belong to other people.
Clean before AI swaps them for placeholders such as [NAME_1] and [EMAIL_1] on your device, so the AI still understands who is who without seeing the real details. Paste the AI’s answer back and the originals are restored, ready to send.

- 3
Copy the clean text, then paste the answer back to restore it.
Questions
Is my original text sent anywhere?
No. The cleaning and the list of replacements stay in your browser tab. Only the cleaned text you copy goes to the AI.
Which AI tools does it work with?
Any of them: ChatGPT, Claude, Gemini, Copilot or your company’s own assistant. It works on the text before you paste it.
Does it find every name?
It finds emails, phone numbers, IBANs, card and ID numbers automatically. Names you type in yourself. Read the result once before pasting.
