Free, no account · Works offline once loaded · Detection by rules and checksums, not by AI
Paste the AI’s answer. Every placeholder it kept, like [PERSON_1], is swapped back for the value it stood for, using the mapping held in this tab.
A detection engine runs in a background worker on your device. It uses patterns, checksums such as IBAN mod 97 and Luhn, and context rules. Open your browser's network tab: your text is never sent.
Every finding is highlighted. Untick what should stay, add your own terms, then choose placeholders, masks, fake data or hashes.
With placeholders, paste the AI’s reply into Restore and the original values come back. The mapping stays in this tab unless you export it.
