Supported languages

CaptionHub supports a growing list of languages across all services and features. To explore what's available, visit our Supported languages page, accessible both publicly and via the app.

Use the Filter list menu to search by service, provider, spellcheck support, or styleguide availability.

Click any language to view detailed support information, including which services are enabled or unavailable for that specific language.

If a styleguide is available, it will appear at the bottom of the page. Where available, this section will contain a set of predefined rules that determine how subtitles should behave—covering grammar, segmentation, and advanced formatting.

You can also preview the styleguide in action by pasting a sample of text. This shows how your subtitles would appear, based on the language-specific rules.
