Use cases

Use AI on your files, without breaching secrecy.

Every use case follows the same rule: identities are replaced on your computer before the copy goes to ChatGPT, Claude, Le Chat or Copilot, and the real names come back into the answer, with you. Here, task by task, is what to mask, the method and the instructions to give the AI.

Frequently asked questions

The short answers.

Can I use ChatGPT on a file covered by professional secrecy?

Not in clear text. The French Bar's guide (CNB, April 2026) recommends systematically pseudonymizing or anonymizing data before any use of a generative AI, and the French accountants' Order says the same. A copy pseudonymized on your computer no longer contains the identities; the mapping table stays with you.

Does the AI still understand the file once names are replaced?

Yes: the same person keeps the same label in every document ([PERSONNE_1], [ORGANISATION_2]…), and you can rename a label, for example [CLIENT] or [TARGET]. The reasoning stays intact; only the names have changed.

How do I get the real names back in the answer?

Paste or import the AI's answer into AnonymFiles: the labels become the real names again, on your computer, as text, Word or PDF.
