What CaptionGo is

CaptionGo adds bilingual subtitles to web videos and can create real-time AI captions when subtitles are missing. It supports translation into more than 100 languages and offers caption styling. Caption capture can use network interception, site detection, TextTrack, DOM observation, or AI speech recognition. The free plan includes bilingual captions for Zoom, Microsoft Teams, and Google Meet, built-in translation, mobile fullscreen captions and shortcuts, and 17 interface languages. Free real-time AI captions are limited to 30 minutes per day, while unlimited use is available with your own key. PRO adds style and position customization, AI translation providers such as OpenAI, Claude, Gemini, DeepSeek, and Ollama, full real-time AI captions, and cloud sync.
