Use AI. Without sensitive data leaving your home.
A-Tool Guard pseudonymizes your Word documents directly at your workstation – allowing you to use ChatGPT, Claude, or Gemini without client data leaving your premises. No cloud. No data sharing.
Three steps to safe AI use
Step 1: Pseudonymize
Open your document in Word. A-Tool Guard automatically recognizes people, organizations, and places and replaces them with realistic replacement names or other placeholders – consistently throughout the entire case.
Step 2 - Working with AI
The pseudonymized version is located in a separate folder. Once approved, you can now submit 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.
