Extension Features
Highly capable and easy to use. Featuring intuitive interface and a few highly performant, but powerful features.
Blazingly fast
The internal logic that manipulates the video is written in plain JavaScript, has a tiny footprint and is blazingly fast.
Limitless platforms
Not limited to any specific video streaming platform. Aims to work everywhere, including embeddable videos.
Minimal interface
Thoughtful design that doesn't get in your way, but provides you with all the necessary options to get the experience you deserve.
Adaptive appearance
Automatically applies the appearance that you have set as personal system preference. If your system is in light or dark mode, the extension will be too.
Cross-browser
Single source of truth, available for all major browsers and tested on Chrome & Firefox. It works in all Chromium based browsers as well.
Magic touch
Toggle between modes with built-in pinch inwards/outwards functionality. It is working on touch screens, trackpads with multi-touch gesture support and also with a mouse-wheel in combination of holding CTRL key on your keyboard.
Internationalization
Supports handful of languages, but aiming to support all major languages with the help of the community.
Keyboard shortcuts
Customizable within the browser built-in interface, rather than extension's interface, to avoid conflicts with other extensions.
