The Client-Data Redaction Kit

Client and finance work is full of details that shouldn't go into any AI tool. This page hides emails, phone numbers from any country, card and bank details, ID numbers (including UK NI, US Social Security, Canadian SIN and Aadhaar), postcodes and any names you list. It swaps them for placeholders like [EMAIL_1]. Paste the safe version into Claude or ChatGPT, then paste the answer back to put the real details in.

There's nothing to install and no code. It runs in your browser, nothing is sent or saved, and you can save the page to use offline.
