How do you translate confidential documents without data leaving the building?

The solution: translate without handing anything over.

The business got an in-house translation tool with an API connection: document in, translated version out — headings, tables and layout stay intact. Nobody pastes paragraphs into a web form any more and rebuilds the document afterwards. The API connection means processing runs through a contractually governed channel — the content is not used to train other people's models and is not collected anywhere. A tool instead of a leak.

That is the difference from the free translator in the browser: there you pay with your content. Here the data flow is settled before the first document is translated. Which data may go into which AI →

Why it works — and where the limit sits.

The AI translates fast and keeps the formatting — but it does not judge whether a wording holds up legally. So the judgement stays with people: contracts and personnel files are checked by the responsible specialist before the translation is used. Nothing goes out without sign-off. That is not a technical restriction but a rule — the same rule that my own business runs on.

“The question is not whether your team translates. The question is where — and who is reading along.”

Does this transfer to your business?

This case transfers to any process involving confidential paperwork: HR, legal, procurement. Wherever confidential paperwork goes into free tools today because it has to be quick, the same route can be built: a tool in the house instead of a leak to the outside. And if one source document is meant to produce several language versions, Case 306 shows how that works in manufacturing.
