Prompt Anonymizer — Replace Names & Entities

Replace person names, organization names, product codes with consistent [PERSON_1], [ORG_1] placeholders so the LLM sees structure but not specifics. Useful when the structure of an internal scenario matters but the actual names shouldn't go to an external API.

How to use the Prompt Anonymizer — Replace Names & Entities

Paste the text. List the entities to replace, optionally with a type prefix (person:, org:, product:). Each unique entity gets a numbered placeholder. Mapping is preserved so you can de-anonymize the LLM's response by reversing the substitution.
