Yes. You can install the extension and use custom speed tuning, rebindable speed hotkeys, in-player buttons, and channel presets for free without entering payment information or creating an account.
Category: PricingWhen you save a custom speed for a creator, your preset is stored locally in your browser storage. As a video loads, the extension compares the on-page channel name locally against your saved list to apply your speed. Because YouTube loads page elements asynchronously, you may notice a brief split-second sync as the channel is recognized. Nothing is ever sent to external servers.
Category: Channel MemoryBacking up and transferring presets is a Pro feature. Free tier users can save up to 3 channel presets directly in their local browser storage. When you upgrade to Pro, you unlock unlimited channel presets plus offline-first import and export for your saved channels and speeds (only those settings, nothing else). Because there is no cloud syncing, your presets remain entirely private within your own local backup file.
Category: Pro FeaturesOur core Speed Up and Speed Down hotkeys can be customized to any single key on your keyboard (such as + and -), making it easy to set up keys that fit your physical layout. The shortcut listener is also case-insensitive, so hotkeys work whether Caps Lock is active or not. (Customizing the 1-Tap Boost key to a letter other than 'B' is available in the Pro version).
Category: Keyboard ShortcutsYouTube Music speed control is a Pro feature. When enabled, you can adjust YouTube Music playback speed using your keyboard shortcuts or directly from the extension toolbar popup (keeping the music player interface completely clean with no injected UI).
Category: Pro FeaturesShorts control is a Pro feature. When enabled in settings, it adds clean speed buttons directly onto Shorts videos and activates keyboard shortcuts so you can adjust Shorts playback to your preferred speed.
Category: Pro FeaturesWhen you upgrade, your unique license key is sent directly to your purchase email. To unlock Pro, simply enter your buyer email and license key in the extension settings. You can activate up to 3 personal devices simultaneously (such as your desktop and laptops) and easily manage or transfer devices anytime.
Category: Pro LicenseNo. The extension never tracks, records, or transmits your watch history, video titles, or browsing activity. To apply channel presets, the extension only checks the channel name locally in your browser against your private storage; no viewing data is ever logged or sent to any server. Free features work locally in your browser without requiring an account or email. When you upgrade to Pro, your buyer email and license key are verified securely only to authenticate your purchase and activate up to 3 personal devices simultaneously.
Category: PrivacySpeed through tutorials, podcasts, and lectures at your ideal pace. Custom speed hotkeys and automatic channel memory help you learn faster without missing a beat.
