| Widget UI | Buttons, labels, system messages, placeholders, and accessibility text. | Officially localized in the 14 languages listed on this page. | Match the page language and verify the rendered widget on the live page. |
|---|
| Source content | The public pages, docs, help articles, and FAQs you choose to index. | Content is only available to answer from when it is public, crawlable, and included in your scrape. | Index every language version you expect visitors to rely on, then check the citations. |
|---|
| Visitor questions and answers | The model may understand and generate languages beyond the 14 localized UI languages. | There is no additional officially tested or quality-assured answer-language count. | Test real questions, answers, refusals, and citations for each audience language before release. |
|---|
| Retrieval and citations | Relevant passages are retrieved from your indexed content; language metadata can help match localized pages. | Cross-language retrieval and answer quality can vary with the query, source content, and model behavior. | Include same-language and cross-language test cases, and confirm that sources open in the intended language. |
|---|
| Unreviewed locales | Locales outside the official widget UI list, including languages the model may still attempt to answer. | Do not treat the UI, retrieval, or answer quality as production-supported without your own review. | Run a locale-specific review or keep that locale outside your supported launch scope. |
