Display as many subtitles as you like. Different languages, translated, auto-generated. NO dependence on any third-party server.

Features & Capabilities

Multi Subtitles Youtube is a straightforward Chrome extension that enables users to display multiple subtitles simultaneously while watching YouTube videos.

It operates safely without conflicting with YouTube's native closed captions and requires minimal permissions, only activating when you choose.

Ideal for language learners and multilingual viewers, this extension enhances your YouTube experience by allowing you to watch with two, three, or even more subtitles at once.

Thanks for making it open source. But it's not working. "Failed to fetch one subtitle" error. I wanted to use it to translate from English to Turkish.

I love the extension. It completely improves the YT experience. I'd tried other options, and they didn't work quite right.
