Is my text sent to a server?

No. All processing happens in your browser using JavaScript. Nothing is uploaded or stored externally.

What is the difference between redaction and anonymization?

Redaction replaces structural PII (emails, SSNs, IPs) with a placeholder like [REDACTED]. Anonymization replaces specific domain words — company names, people, projects — with realistic-sounding generic names like Acme Corp or Alice, keeping the document readable.

Do my mappings persist across sessions?

Yes. Your manual pairs and category mappings are saved to your browser's localStorage. They are available the next time you visit.

What if I run out of names in a category pool?

The tool appends a counter to the last pool name. For example, after Tailspin Toys is used, the next company becomes Tailspin Toys 2.

Can I use this for GDPR compliance?

This tool is a convenience utility, not a compliance solution. For regulatory requirements, use a dedicated data governance platform. This tool is best suited for quickly preparing text before sending it to an AI assistant.
