Stremio does not provide any content, everything is provided by system of addons it means that in Stremio we do not have any means to control available content, add it or modify.
Subtitles are available in many languages for most titles. If subtitles aren’t available in a language, it may be due to:
- Your location - some countries block access to subtitles addons(like Sweden blocks access to the opensubtitles)
- The movie or tv show you are trying to watch - Simply no one has translated subtitles to your language
At the moment for top titles stremio has subtitles in most popular languages :)
