Trancy: AI Bilingual Subtitles & Translation Extension

Trancy is a browser extension built for language learners who want to study through content they already love. By overlaying bilingual subtitles on platforms like YouTube, Netflix, Disney+, TED, Udemy, Coursera, and edX, it transforms passive video watching into an active immersion exercise, letting users see both their native and target language simultaneously while they follow along with dialogue and narration. Beyond video, Trancy extends its AI translation engine to the entire web, offering full-page immersive translation and instant word or sentence lookups as you browse articles, blogs, or documents. It even includes a PDF AI Translator for tackling foreign-language readings outside the browser. Rounding out the experience are built-in vocabulary and grammar tools plus listening and speaking practice modules, giving learners a well-rounded toolkit that goes far beyond simple subtitle translation. Whether you're a self-taught polyglot, a student supplementing classroom study, or an educator building lesson materials, Trancy aims to make language acquisition feel less like homework and more like an extension of your normal streaming and browsing habits.

Install the Trancy browser extension and select your target language during setup. Head to a supported platform like YouTube or Netflix to activate bilingual subtitles alongside your videos. While browsing any webpage, enable the AI-powered translation tools for instant word, sentence, or full-page translation. Use the built-in vocabulary, grammar, listening, and speaking modules to reinforce what you've learned, and upload PDFs to the AI Translator for offline reading materials.
