SubText

About

Turn the shows and films 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, base form, and an example sentence.
- Expression highlights — choose which kinds of expressions, like idioms and slang, are highlighted in the subtitles, so the ones you’re learning stand out.
- 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 — colors, sizing, position, keyboard shortcuts, and separate settings per site.

Works where you already watch — major streaming and video-learning sites, including Netflix and YouTube.

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.
