Version 1.0.0
Released Jun 25, 2026 - 1.91 MBWorks with firefox 140.0 and later, android 142.0 and laterFirst release of CaptionGo — bilingual subtitles and real-time AI captions for any video, on PC and mobile browsers.
- Bilingual subtitles: Automatically show "original + translation" on web videos, or view translation-only or original-only; works on major platforms like YouTube, Netflix, Disney+, Hulu, and Bilibili as well as ordinary web videos, and hides the site's own subtitles to avoid overlap.
- Smart sentences: Automatically merges fragmented, word-by-word captions into smooth, complete sentences.
- Real-time voice captions: Turn speech into subtitles and translate them even for videos without captions. Use the built-in service for free, or add your own Deepgram key / connect a local transcription backend — 50+ languages supported.
- Multiple translation services: Built-in free translation via Google, Microsoft, Yandex, and Chrome; or connect AI models like OpenAI, Claude, Gemini, and Ollama with a customizable translation style. Automatically falls back to a backup service when the current one is unavailable.
- Meeting captions: Automatically display a translation beneath the captions in Zoom, Microsoft Teams, Google Meet, and Twitter Spaces (off by default; turn on the meeting's own captions first).
- Rich caption styling: Freely adjust font, size, color, stroke, background, and position; style the original and translation separately; drag to reposition and remember it per site.
- Floating button: A draggable, collapsible floating button on any web page lets you turn captions on anytime, and can be hidden on specific sites.
- Mobile fullscreen support: Captions and settings work the same way when watching video in fullscreen on mobile browsers.
- Keyboard shortcuts: Toggle bilingual subtitles and live voice captions with one key; shortcuts are customizable in your browser's extension shortcut settings.
- Cloud sync (PRO): End-to-end encrypted sync of your settings and API keys — switch computers or sign in on mobile with the same account to sync automatically, with no reconfiguration.
- Account & membership: Sign-in, trial, and subscription supported.
- Multi-browser & multilingual: Supports Chrome, Edge, Whale, and Firefox (including Android), with a multilingual interface.
