Use AI. Without sensitive data leaving your home.
A-Tool Guard pseudonymizes your Word documents directly at your workstation – enabling you to use ChatGPT, Claude, or Gemini in a legally compliant manner. No cloud storage. No data sharing.
Three steps to safe AI use
Step 1: Pseudonymize
Open your document in Word. A-Tool Guard automatically recognizes all people, organizations, and places and replaces them with realistic replacement names or other placeholders – consistently across the entire case.
Step 2 - Working with AI
The pseudonymized version is located in a separate folder. You can now safely transfer these files to Chat GPT, Claude, or any other AI tool.
Step 3 - Re-identify
Place the AI result back in the folder. A-Tool Guard will reinstate the real names at the touch of a button – with a confidence report for final verification.

Battle-tested in the public sector.
Our NLP models for German and French have been used by authorities and courts for years - not generically, but trained on legal texts.
Audit-ready from the first click.
Every step is logged. The confidence report shows which names were recognized, which were filled in using fuzzy logic, and which were marked for review. The required human oversight ("human-in-the-loop") is an integral part of the product.
