Input the text you want to send
Hidden characters 0 found
Pasted text can carry characters you cannot see: zero-width marks, text-direction overrides, and tag characters that a person cannot read but a model can. A job description, a contract, or a web page can carry an instruction this way.
Name the names people and companies are not detected
No regular expression finds a name without guessing, and a guess fails silently. So you supply the names, companies, and project words. Everything else is confirmed by a checksum or a fixed prefix.

API for agents
An agent can call the same redaction over HTTP, to scrub text before it forwards or logs that text. There is no restore endpoint. Reversal needs the real values, so it stays in this browser.
