Smart subtitle search with optional bring-your-own-key AI translation.
Pick the languages you want and which sources to query. SubDL gives the best matches; OpenSubtitles and Podnapisi work with no key.
Translate any found subtitle into your language in real time, using your own API key. Timestamps and formatting are preserved; results are cached so you only pay once.
Leave this OFF. Subtitles are fetched directly over HTTPS and work on web, mobile, Android TV, Nvidia Shield, and iOS. Turn it on only if subtitles fail to load on a device that can't reach your server URL but does run Stremio's local player — it routes through 127.0.0.1:11470 instead.
