Anonimise

Anonymise sensitive documents before they ever reach an online AI — with a tool that runs fully offline, so no client data leaves the office.

Professionals want to use AI, but can’t paste client files into ChatGPT. Anonimise is the tool you run first — it scrubs names, addresses, BSNs and bank numbers out of a document, so what’s left is safe to send to an online model.

It runs entirely on your own computer. The AI inside is a local name-recognition model — not a chatbot, never connected to any cloud — paired with strict rules for data that has a fixed shape, like the BSN’s 11-proef checksum and IBANs. Pull the network cable and it works exactly the same; it actively blocks itself from going online.

Out comes a clean text version with names swapped for neutral placeholders, plus a properly redacted PDF or Word file with the sensitive text removed, not just blacked out. You stay in charge — review every match, add your own words to redact — and nothing ever leaves your machine. Built with Lexpert Advocaten.
