CheckIDs Try the redaction API

Remove personal data before it reaches your LLM

Paste a text (up to 300 characters) and see what an AI model would receive: names, national ID numbers, IBANs, emails and phone numbers replaced by placeholders, and the map that lets you restore them afterwards. No signup needed.

Try a sample:

This demo sends the text to the API and returns the result; nothing is stored. 5 requests per minute. See privacy.

Use it in your own app. The free plan gives you 500 requests a month for texts up to 50,000 characters, with entity types, masking and offsets. Start with the quickstart: curl, Python, JavaScript, LangChain, n8n and MCP.
