What Copilot does in translation & localisation

Core tasks in translation & localisation
Where Copilot is strong
  • Deep Microsoft 365 integration
  • Grounding on your own data via Microsoft Graph
  • Strong enterprise governance and compliance
  • Choice between GPT and Claude models

Copilot has a concrete GDPR point to consider. The Claude models within Copilot officially fall outside the EU Data Boundary. If you want strictly EU-only processing, exclude the Claude models in the admin panel. Weigh this heavily before using it in translation & localisation.

Confidentiality and GDPR

GDPR: Caution

Client source documents often contain personal data or trade secrets: never use the free consumer version of a translation tool for client material. Require a data processing agreement, check that your texts are deleted after translation and not used for training, and choose EU hosting where possible. Many translation contracts and NDAs with end clients prohibit passing texts to third parties without consent, so document which MT engine you use. And stay responsible for the content: AI translations read fluently but can reverse figures, negations and legal nuances.

Microsoft 365 Copilot (business) falls under the EU Data Boundary and does not train on tenant data. Consumer Copilot does train by default, with an opt-out.

Rule of thumb Use the business variant with a data processing agreement, and keep a human in the loop for decisions that matter.
