What exactly does the AI see?

Natural text where every sensitive value has been replaced by a believable fake. The AI works as usual; only you can restore the real data, from the encrypted vault on your machine.

What about payroll documents, payslips and DSN filings?

These are the most sensitive: NIR social-security numbers, contact details, identities. Anoni detects and replaces them, and the dictionary catches your internal references. Review before sending. The tool helps. It doesn't decide for you.

For accountants

Review note

The file for Claire Fontaine contains missing supporting documents. These must be collected before the financial year is closed.

One name illustrated. Always review the full export.

In practice

Draft a document request

Give AI the context for a follow-up with identities replaced.

Review bank details, references, and information specific to your client.

Client letter, contract, tax return, report. PDF, DOCX, Excel, email, TXT, Markdown, CSV or image. Nothing leaves the machine.

Every day

Every part of the file deserves care.

French identifiers

SIRET and SIREN company numbers validated checksum-included, NIR social-security numbers, IBANs: detected as such, not guessed from context.

A record to keep

Every job produces a local report: categories, counts, SHA-256 fingerprint. No personal data.

The firm's dictionary

Your clients, your files, your internal references: added once, masked everywhere.

Reference points

Your professional framework.

Sources: “How to use ChatGPT?”, notice from the French institute of chartered accountants (Ordre des experts-comptables) · France Num guide for accountancy firms.

“Do not upload personal, sensitive and/or confidential data: no client emails, FEC accounting ledgers, DSN payroll filings… that aren't anonymized, into sites you don't control.” The instruction is set: anonymize first.

Questions

Before your first document.

No. The data still leaves the firm, and the provider becomes a processor you must oversee: contract, records, vigilance. The institute's notice targets the sending itself: no un-anonymized client data. Anonymized before it's sent, it no longer exposes anyone.

Try it with one document.

Open it. Review the detections. Choose your export.
