Text Anonymizer for AI
Remove emails, phones, card numbers, IDs and names before pasting text into ChatGPT or Claude — then restore them. Runs in your browser.
Private by design: everything runs in your browser. Nothing you paste here is sent to our servers or stored.
Pattern matching can't reliably detect names — list the ones that matter.

Why anonymize before using AI?
Pasting customer emails, lead lists or contracts into AI assistants can expose personal data. Replace identifiers with placeholders first, get the AI's help, then restore the real values locally. Read the full guide: how to remove personal data before pasting into ChatGPT or Claude.
Limits
Detection is pattern-based. It catches common formats (emails, phones, cards, IDs, IPs, URLs) and the names you list, but not every identifier. Always review the output.
