What should be anonymized
- Names, emails, phone numbers, and addresses.
- IBANs, VAT numbers, national identifiers, and account references.
- API keys, access tokens, passwords, and client secrets.
How to anonymize AI prompts before sending them.
AI prompt anonymization means replacing raw personal data, financial identifiers, and secrets with placeholders before a prompt leaves the browser.
Why anonymization is useful
Many prompts still need structure and context. Replacing values with placeholders keeps the prompt readable for the AI model while reducing exposure of the original data.
What makes a good anonymization workflow
- Detection happens before send, not afterward.
- Placeholders are stable enough to preserve reasoning context.
- The user can still understand what was protected.
- Processing happens locally whenever possible.
