Key Features
Unlike Picture-in-Picture, it stays within the page. When you scroll down, the floating player automatically appears.
You can also use your Mac trackpad to adjust size, position, and more.
Supports two caption modes: a high-readability caption style and one that restores YouTube's original caption appearance.
Flexible Adjustment
Drag the floating window to move it freely, or drag the edges to resize it to your preferred size. Trackpad gestures are also supported.
Caption Optimization
The extension provides additional optimizations for captions, balancing readability and functionality, keeping them clear and readable even when the floating window is small.
Picture-in-Picture Enhancement
Enhance the browser's native Picture-in-Picture feature to display YouTube CC subtitles in Picture-in-Picture mode.
- • Support for displaying YouTube subtitles in native Picture-in-Picture player
- •
Support automatic Picture-in-Picture for an experience similar to Arc browser Learn More
Trigger Conditions:
This feature is disabled by default. You can freely control how automatic Picture-in-Picture is triggered.
- Page state changes
- Tab state changes
Important Notes:
Automatic Picture-in-Picture will only trigger when you actually leave Safari and switch to another application.
Picture-in-Picture will not activate in the following situations:
- Only switching to desktop or opening Finder and System Settings (System Preferences)
- Still operating within Safari (e.g., using extensions, opening settings, or developer tools)
- Continuing to operate on another screen when using multiple displays
After first opening a YouTube page, you need to interact with the page once (e.g., click the play button) to confirm the current video. After that, automatic Picture-in-Picture will take effect. This is a browser security mechanism requirement.
All judgments are based solely on window and application states provided by macOS, completed locally, without requiring Accessibility permissions, and do not read or record any browsing content.
- • Customize Picture-in-Picture subtitle appearance through system preferences
- • Subtitles sync with the video's subtitle language settings
- • Support for displaying YouTube subtitles in Picture-in-Picture window
- • Subtitles sync with the video's subtitle language settings
- • Automatically trigger Picture-in-Picture when switching tabs
Since Mozilla Firefox has officially implemented automatic Picture-in-Picture and Picture-in-Picture subtitles, this enhancement is not implemented.
Chrome's Picture-in-Picture subtitle feature is currently in Beta. It can display subtitles in Picture-in-Picture, but due to Chrome's different implementation (drawing-based rather than native video), it does not support highest quality, HDR effects and DRM protected videos
To properly capture subtitles, refresh YouTube pages after enabling to get subtitle data
You can click the CC subtitle button to enable subtitles
