Stable bilingual subtitles for YouTube with automatic translation fallback, draggable positioning, and custom styles. TwinCaption displays the current YouTube caption track and your chosen translation together in one stable subtitle layer.16+ Languages Supported! Built for language learning, technical videos, interviews, and anyone who wants the original and translated captions visible at the same time. Features: • Original, translated, or dual-subtitle display modes • Drag subtitles anywhere on the player • No account, analytics, advertising, or paid API key YouTube translation is the default. Google translation is optional and disabled by default. If enabled, TwinCaption asks for access first, then sends subtitle text directly from the browser to Google for translation. The optional service may be rate-limited. TwinCaption is an independent extension and is not affiliated with, authorized by, or endorsed by YouTube or Google. Chrome may display an access warning for `translate.googleapis.com` during installation or update. This is expected and is required only for the automatic fallback above. Allow it to enable fallback translation. TwinCaption adds no Google account identifier, has no developer-operated backend, and the developer never receives or stores subtitle text. Google processes translation requests under its own privacy policy and terms. ### 关于Google 翻译与 Chrome 权限提示 TwinCaption 会优先使用 YouTube 翻译。只有当 YouTube 没有当前字幕句的可用译文时，插件才会将**当前字幕文本和目标语言代码**直接发送到 `translate.googleapis.com`，用于自动翻译兜底。 安装或更新时，Chrome 可能显示关于 `translate.googleapis.com` 的访问权限提示。**这是正常提示**，该权限仅用于上述自动翻译兜底，请>允许以启用该功能。TwinCaption 不会附加 Google 账号标识，不设开发者服务器，开发者不会接收或保存字幕文本。翻译请求由浏览器直接发送 给 Google，并受 Google 自身隐私政策与条款约束。
