Quick answer
A dual subtitles Chrome extension lets you watch a video with two subtitle lines at once. 2Subs adds one line from the original captions and one translated line, so Netflix, YouTube, anime, K-drama and streaming lessons can become language-learning input without leaving the player.
What is a dual subtitles Chrome extension?
A dual subtitles Chrome extension shows two subtitle lines on the same video. One line keeps the original captions visible. The second line gives you a translation, so you can understand the scene without leaving the player.
Where 2Subs works
2Subs is built for major desktop streaming and video sites including Netflix, YouTube, Disney+, Prime Video, Max, Hulu, Crunchyroll, Apple TV+, Peacock, Paramount+, MUBI, Plex and more. Support depends on the site exposing subtitle data that the extension can read.

Why learners use dual subtitles
Language learning gets easier when sound, spelling and meaning appear together. Bilingual subtitles let you stay in the story while your target language remains visible.

How to use 2Subs

2Subs vs manual translation
Manual copy-paste translation is fine for a single phrase, but it breaks the habit of watching. 2Subs keeps the translation close to the audio and image, which makes it easier to connect sound, spelling and meaning while you stay in the story.
Dual subtitles FAQ
Does 2Subs create subtitles when a video has none?
2Subs works best from available captions or timed-text streams. If a site or video does not expose subtitle data, support can be limited.
Can I use 2Subs on a phone?
No. 2Subs is a desktop browser extension for Chromium-based browsers, not a mobile app extension.
