Remove personal information (PII) from text
Need to share logs, a support transcript or a document without the personal data in it? Paste the text and the sensitive values are detected and replaced with neutral tokens, so you can share or store the result safely. It runs on your device — the original text is never uploaded.
What counts as PII here
The detector finds emails, phone numbers, credit-card numbers (validated with the Luhn checksum to avoid false hits), IBANs, US Social Security numbers, IP addresses, API keys and common ID numbers — the identifiers that most often need removing before text is shared.
Accurate, not just pattern-matching
Card numbers must pass a checksum, IBANs a mod-97 check and SSNs their allocation rules, so the results aren’t flooded with false positives. When two patterns overlap, the more specific one wins, so a card is never mislabelled as a phone number.
Reversible when you need it
The same tool can put the real values back later using an in-browser token map, which is handy when you’re round-tripping text through another system (like an AI assistant) and need the originals returned.
FAQ
Is the text uploaded to be scanned?
No. Detection runs entirely in your browser; the text you paste never leaves your device.
Will it catch everything?
It reliably catches structured identifiers (emails, numbers, keys). Free-form items like names and postal addresses are harder and are handled by automatic name/address detection, which is coming soon — for now you can remove those manually.
Is it free?
Yes, completely — and there’s no sign-up for the on-device tools.
