About this extension

Turn anything you watch into language practice.

SubText shows two subtitle lines at once — the original and a translation — so you can follow along and pick up a language naturally while watching the shows you already love.

What you get:
- Dual subtitles — original + translation, synced to playback.
- Three translation modes — context-aware AI translations, fast machine translation, or the site's own caption track.
- Hover a word for an instant meaning, without pausing.
- Click a word or phrase for a deeper breakdown: definition, part of speech, example sentences, and word forms.
- Expression highlights — idioms and set phrases are flagged so you notice them.
- Follow-along — words light up as they're spoken.
- Save to your library — keep words and phrases and review them later with flashcards, quizzes, and study sets on subtext.site.
- Make it yours — fonts, colors, sizing, position, keyboard shortcuts, and separate settings per site.

Supported sites: YouTube, Netflix, Disney+, Prime Video, Hulu, Viki, and Udemy.

Free to use: machine-translated dual subtitles, word hover, and lookups work without an account. A SubText subscription unlocks higher-quality AI translations and saving to your personal library.
