Trancy

Trancy is a comprehensive language learning companion that transforms how you interact with foreign language content. It provides accurate AI-generated bilingual subtitles for video platforms like YouTube, Netflix, HBO Max, and educational sites like TED and Coursera. Beyond videos, it offers text selection translation on any webpage, full-page immersive translation, and a learning center where you can save vocabulary and sentences for review.

The tool stands out with its AI-powered features including word lookup with detailed definitions, grammar analysis that breaks down complex sentences, and intelligent sentence segmentation that organizes subtitles for better translation accuracy. It supports multiple translation engines (Google, DeepL, Microsoft, OpenAI) and offers practical features like playback speed control, text-to-speech, and customizable subtitle fonts. The reading mode lets you focus on subtitles while keeping the video visible, making it easier to follow along.

Language learners at all levels benefit most from Trancy, particularly those who consume foreign language videos regularly or read content in other languages online. Real-world use cases include watching Netflix shows with dual subtitles to improve listening comprehension, reading news articles in foreign languages with instant translation assistance, and building personalized vocabulary decks from content you encounter daily. It's especially valuable for self-directed learners who want to integrate language practice into their existing media consumption habits.
