Text Anonymizer — masks emails, phone numbers, and card numbers right in your browser

What to mask

Phone detection is a heuristic: it doesn't guarantee full coverage of every international number format.

It masks only emails, phone numbers and card numbers. Names, addresses and document numbers stay in the text, so this is not anonymization in the legal sense.
