The problem
Localization errors (incorrect context, the wrong language shipped to a market, off-brand terminology) were being caught late in the production cycle, sometimes after content had already published to multiple surfaces. Each catch meant updates across several markets and a manual review sweep.
The approach
The agent I set up in M365 Copilot reviewed localized content against the source at the point of import, before it entered production. It applied rules for grammar, style, sales terms, and brand terminology. It flagged issues with enough context for producers to fix them directly or share specific examples with the localization team, even in languages they couldn't read. In our case, the review helped us identify errors and patterns we hadn't been aware of.
The result
Manual spot-checking gave way to an automated review step. Errors that used to spread across several markets got fixed before they left the producer's hands.
