Despre această extensie
CaptionGo adds dual-language subtitles and AI-powered live captions to the videos you already watch, helping language learners and anyone watching foreign-language content follow every line.
Unlike tools that only translate an existing subtitle track, CaptionGo shows the original subtitle and its translation at the same time — and when a video has no captions at all, it transcribes the speech into real-time captions for you.
Core features are free forever, with an optional PRO upgrade.
Free
- Bilingual subtitles (Basic): turn on a site's captions and CaptionGo appends a translation line in place — ideal for learning a language by watching videos or learning English with TV shows and movies.
- Free translation engines: a built-in on-device translator plus Google and Microsoft.
- Automatic captions: turns on a site's own closed captions (CC) the moment playback starts, with per-site rules.
- Live captions (speech-to-text): a free daily allowance transcribes audio for videos with no subtitles, using AI speech recognition (ASR).
PRO
- Advanced bilingual subtitles: read the original subtitle data for preloaded, no-wait, full-sentence translation on a dedicated overlay.
- Full subtitle customization: font, size, color, background, outline, and on-screen position.
- AI subtitle translation: connect your own AI provider such as OpenAI, Gemini, and DeepSeek for natural, context-aware results.
- More live captions (ASR): extra usage and the option to use your own speech-to-text key.
- Cross-device sync: end-to-end-encrypted cloud sync — set everything up on your computer, then just install and sign in on your phone.
Great for
- Learning English (or any language) by watching videos
- Following online courses and lectures
- Understanding foreign-language movies, news, and livestreams
- Getting captions on videos that ship without subtitles
Works across the web, from streaming sites like YouTube, Netflix, and Bilibili to online course platforms and most embedded video players.
