Mapping placeholder → original · lives in this tab only
Each distinct value gets one stable placeholder, so the AI can still follow the log. Close the tab and this table is gone.

Paste the answer you got back. Placeholders like <IPV4_1> are swapped for the real values from the mapping above.
What it catches
Anthropic, OpenAI, GitHub, AWS, Google, Slack, Stripe and Telegram tokens · JWTs · private keys · passwords in URLs and key=value configs · IPv4/IPv6 · MACs · internal hostnames · home-folder usernames · emails · phone numbers · cards (Luhn) · IBANs (mod-97).
Why it is safe
No server, no analytics, no storage. The page's Content-Security-Policy sets connect-src 'none', so the browser itself refuses any network request. Check the source — it is two small files.
What it is not
Pattern matching, not a guarantee. Unknown secret formats and names in free text can slip through — add them under “also redact” and read the output before you send it.
