About Sublo

Sublo adds a second subtitle track to streaming video so viewers can watch with two languages at once, picking any pair from more than 50 languages. Translation happens in real time and stays in sync. Supported services include YouTube, Hulu, Peacock, Paramount+, Plex, MUBI, Apple TV+, Crunchyroll, Prime Video, Disney+, Max and Netflix.

Setup takes about thirty seconds: install the extension, turn on subtitles in the streaming service briefly so Sublo can load them, and choose the two languages. Font size, color, position and background opacity can be set for each track, and subtitles stay visible in fullscreen. The site says no account is needed, viewing habits are not tracked or stored, and subtitles are read locally from the user's existing subscription rather than hosted. It runs in desktop Chrome, with an Edge version, and has a free plan alongside monthly and yearly paid options.
