Instant
Pattern rules catch emails, phone numbers, card and bank numbers, IDs, dates and URLs while you type, with nothing to download.
Your choice of replacement
Use [REDACTED], category labels like [EMAIL], consistent pseudonyms, ███ blocks, or remove the text entirely.
Smarter with AI, still private
Turn on a small AI model to also find names, organizations and places. It downloads once and runs offline in your browser.
Questions
What does it detect?
Emails, phone numbers, card numbers (checksum-verified), IBANs and bank numbers, ID numbers, dates, ages, URLs and IP addresses. With AI on: names, organizations and places.
Is my text sent to an AI service?
No. The AI model runs inside your browser. The page’s security policy doesn’t allow it to send your text anywhere.
Which languages work?
Pattern rules work in any language. The AI model that finds names is trained on English.
Can I always hide certain words?
Yes. Add them to “always hide” and they are covered wherever they appear. The list is saved on this device only.
