Three language choices
The application's interface language changes labels, navigation, and messages. Content language controls a new drafting task or schedule. The Help Center language chooses which translation of a guide you read. These choices are separate.
Change the application interface
Use English / Tiếng Việt on the application's sign-in or workspace screens. Before signing in, a saved preference takes priority, followed by a supported browser language; the current fallback is Vietnamese. After sign-in, the workspace's saved choice takes priority.
A signed-in change is saved to your workspace for later visits. If saving fails, keep the previous selection and try again when the connection works. Switching should preserve the current route, selected sources, and unsaved edits.
Choose the language of a draft
Use Content language in Chat before sending. For a daily schedule, set its separate language field and save the schedule. Want an English draft while using Vietnamese buttons? Keep the interface in Vietnamese and choose English for the content.
Changing a selector does not rewrite a stored draft. Request an appropriate revision if you want different wording, then review and approve the new saved revision.
Read help in another language
Use the selector in this Help Center's header. Translated pages keep the same article route; if a translation is missing, the destination is that language's home page. The chosen language stays in the address when you reload. This selector does not sign you in or update the application's workspace preference. Prompt examples keep the language explicitly shown in their text.
