Keep translations consistent with a glossary

Define a workspace translation glossary for key terms, acronyms, and brand names.

Today, we’re introducing Translation Glossary — so your company, product, and industry terms stay consistent across languages. Available for creators on Enterprise plans.

How it works and why it matters

You can now define a workspace-level glossary to control how specific terms are handled in translations.

Override how a term is translated (per language, and even per locale)
Mark terms as do not translate (great for acronyms and brand names)
Import and manage terms in bulk via CSV

Glossary rules apply to new translations, which reduces manual cleanup and helps teams scale multilingual video faster.
