The workbench · a free tool
Strip the private parts out of text before you hand it to an AI. The model sees the shape of your data, never the secrets.
Runs entirely in this tab · nothing is sent anywhere · this page has no analytics

Paste the AI’s answer below. Any tokens it carried through get swapped back to the real values, using the map from your last scrub. This also never leaves the page.
What it catches: Social Security numbers, EINs, credit and debit card numbers (checksum-verified), bank routing numbers (checksum-verified), phone numbers, email addresses, IP addresses, street addresses, and every custom term you add. What it cannot catch: names it has never been told about. Add them as terms above; a machine that guessed at names would miss some and you would trust it anyway, which is worse.
Open your browser’s developer tools, watch the network tab, and use the tool. After the page loads its fonts, there is nothing to see. There is no server on the other end of this and no analytics script on this page. The whole build is readable in this page’s source, and the design behind it is in the write-up.
