About this extension
SubBridge translates subtitles displayed on video websites into your preferred language. Whether you're watching anime, movies, or other content on YouTube and supported streaming websites, SubBridge helps you understand what you're watching without leaving the page.

Features
  • Instant subtitle translation: Translate existing video subtitles as you watch.
  • Multiple translation engines: Use Google Translate or DeepL, or choose AI-powered translation through services such as OpenAI, Google Gemini, Anthropic Claude, DeepSeek, OpenRouter, and others.
  • AI translation: Optionally use AI models for more context-aware and natural translations.
  • Custom API support: Configure compatible API endpoints and use your preferred translation service.
  • 40 languages: Choose your preferred source and target languages.
  • Customizable appearance: Adjust the appearance of translated subtitles to suit your preferences.
  • Translation glossary: Configure preferred translations for names and terminology when using compatible AI providers.
  • Context-aware translation: Give supported AI models additional subtitle context to improve translation consistency.
  • Flexible settings: Customize translation behavior and other preferences.

How it works

SubBridge works with subtitles already displayed by supported video websites. Enable subtitles on a video, activate SubBridge, and let it translate them into your chosen language.

No subtitle files to upload. No need to download videos. Just translated subtitles while you watch.

Translation services

SubBridge supports Google Translate, DeepL, and various AI translation providers. Some services require an API key and may incur usage costs. Available features depend on the selected provider.
