T3AI also supports **DeepL Official Glossary** mapping.
Use this when you translate with DeepL and want DeepL glossaries applied for specific language pairs.

<Note>
  DeepL Official Glossary works with the **DeepL provider only**.
  It is not applied when you translate with other AI providers (for example, ChatGPT).
</Note>

**How to map a DeepL glossary:**

1. Open **AI Assistant** and go to the **Translation** tab.
2. Click **Manage Glossary**.
3. Open the **DeepL Official Glossary** tab.
4. Select the target language.
5. Select the DeepL glossary to map for that language pair.
6. Click **Save mapping**.
7. Optionally open the saved mapping (eye icon) to review the details.

When you localize a page and choose **Translate with DeepL**, the mapped DeepL glossary is used for that language.
