LumaSub: Live Speech-to-Subtitle Translator

Follow foreign-language videos, live streams, chats and web pages: speech and text are translated into your language as you watch.

Foreign-language live streams, videos and web pages, understood as you watch. Speech becomes captions in your language in real time, and live chat and web pages get translated too. 🎬 Video and live stream captions • Instant mode: captions the moment someone speaks • Precise mode: captions appear right as the words are spoken, with tighter timing • If a video already has captions, LumaSub translates those directly: more accurate, and it uses less of your translation time • Speakers are told apart, each one in a different color • Drag captions anywhere on the video; size, opacity and pace are yours to adjust • Your whole computer's sound works too: meetings, players and other apps 💬 Live chat • Messages are translated into your language, fast enough to keep up even with busy streams • One click sums up what chat is talking about • Type in your language, get it in the stream's language, then copy and paste to post • Works with more live streaming sites, including popular Korean and Japanese platforms 🌐 Web translation • Translations appear right under the original; choose “Translation only” and the site reads as if it were written in your language • Buttons and menus switch to your language too, and new content is translated as it appears 📖 Look back and keep • The Reading panel keeps recent captions; click a line to jump the video back to that moment • Save captions as a file; the glossary translates names and terms the way you choose 🌏 Interface languages: 繁中, 简中, English, 日本語, 한국어, Español, Français, Deutsch, Português, العربية, हिन्दी, Bahasa Indonesia ✨ New in 2.6: whole-computer sound translation, captions you can drag anywhere, speakers in different colors, more live streaming sites, web “Translation only” 💰 Pricing • New accounts get a 15-minute free trial with every feature included • Monthly plan: USD 14.99 for 30 hours a month (renews automatically, cancel anytime) • Time packs: 5 hours USD 4.99, 15 hours USD 12.99, never expire • Precise mode counts 1 minute watched as 2 minutes; chat, web and caption translation use time based on the amount of text, so busy streams with lots of messages use it faster • Refundable within 14 days of purchase if unused; prices may not include tax 🔒 Privacy No recording, and no record of what you watch.
