CaptionGo – Bilingual Subtitles & Real-Time AI Captions for Any Video
Watch any video with subtitles in your language. CaptionGo translates native captions into 100+ languages and shows them side by side — and when a video has no subtitles at all, real-time AI captions step in. Works on desktop and mobile browsers.

What is CaptionGo?
CaptionGo adds bilingual subtitles to videos on any website. It picks up the video's native captions automatically, translates them into your language, and displays both together — original and translation. No subtitles available? CaptionGo can listen to the audio and generate live AI captions in real time. Works on YouTube, Netflix, Coursera, Twitch, and thousands more sites, on both PC and mobile.
- Bilingual display — see the original caption and your language side by side, perfect for language learning and foreign content
- Real-time AI captions — when a video has no subtitles, speech recognition generates live captions on the fly
- Mobile fullscreen ready — a dedicated touch-friendly menu keeps captions visible and adjustable even in mobile fullscreen playback
