━━━━━━━━━━━━━━
🎬 DUAL SUBTITLES ON EVERYTHING YOU WATCH
See the original line and your translation together, styled your way — font size, position, and languages switchable mid-episode. When a platform already has subtitles in your language, Polyscript uses them automatically for perfect accuracy.
🗣️ HEAR YOURSELF SPEAK FLUENTLY — BEFORE YOU CAN
Polyscript clones your voice and speaks any subtitle line with it, in perfect accent and rhythm. Then Shadow Coach hands you the mic: repeat the line and close the gap between you and the fluent you. That's not sci-fi — that's your daily practice loop.
📜 LIVE TRANSCRIPT, ALWAYS IN SYNC
A scrolling transcript follows every line of dialogue. Missed something? It's right there. Never lose your place again.
🔤 HARD SCRIPTS, MADE READABLE
Pinyin over Chinese. Romaji over Japanese. Romanization for Korean, transliteration for Sanskrit and beyond — with smart word segmentation so you can see where words begin and end.
📖 TAP ANY WORD
Click a word in the subtitle for an instant dictionary and grammar breakdown — yes, even Latin and Ancient Greek morphology.
🏛️ LANGUAGES NO ONE ELSE SUPPORTS
Hundreds of modern languages, plus historical ones that mainstream platforms ignore — Ancient Greek and Classical Latin among them. Watch a thriller in Latin. Seriously.
✂️ CLIP IT, CAST IT
Turn any line into a shareable clip, or cast your session straight to the TV.
📌 SAVE THE MOMENT, STUDY ANYWHERE
Bookmark a scene on your laptop, pick it up on your phone. Your vocab, settings, and progress follow you on every device with one Polyscript account.
