What it does

Trancy turns videos and web pages into language study material with bilingual subtitles, translation, word lookup and reading tools.

Use a video you want to understand, then study a difficult line through the bilingual subtitles or text view. Word lookup and saved material support a closer second pass after watching for meaning. The browser-based approach is useful when you want learning tools attached to existing content rather than another course catalogue.

Free access includes bilingual video subtitles and word or sentence translation, with limits on saved words and sentences. Premium adds larger collections and AI study tools.
