Polyscript

Read subtitles, save vocab, and keep language learning going across web and mobile.

Polyscript — Subtitles for Any Language, on Your Favorite Platforms Learn any language by watching what you love. Polyscript adds dual subtitles, AI translation, and a live transcript to YouTube, Netflix, Disney+, and Prime Video — so you can follow along in your target language without pausing to look things up. Dual Subtitles See the original caption and your translation at the same time. Adjust font size, positioning, and language on the fly. AI Translation Subtitles translated in real time — not word-for-word, but naturally. Translations are cached so playback stays smooth. Live Transcript Panel Follow every line of dialogue with a scrolling transcript synced to the video. Never lose your place. Any Language — Including Rare and Ancient Ones Polyscript goes where mainstream platforms don't. Supported languages include Ancient Greek, Classical Latin, Sanskrit, Biblical Hebrew, Classical Arabic, Classical Chinese, Old English, Middle English, Old Norse, Gothic, Aramaic, Sumerian, and Akkadian — alongside hundreds of modern languages.
