About this extension
⏩ Skips (or fast-forwards) silent parts in videos in real time and completely automatically.

<a target="_blank" href="https://user-images.githubusercontent.com/39462442/131825020-5308b879-0509-41a3-95c9-bb4ad8938dc0.mp4">Video demo</a>

🌐 Supports YouTube, Coursera, Twitch, local files, and (almost) any other website.

Useful for watching 👨‍🏫 lectures,🔴 stream recordings (VODs), 🎙️ podcasts, webinars, 📞 call & audio recordings, and other unedited videos where the speakers spend a portion of time on things other than talking.
But even if the video is tightly packed, it can also save a bit of time, so it's generally fine to keep it always on.

🔃 Easy to turn on and off, without having to reload the page (it's there to save time after all!).

⚙️ Has a lot of different settings, but generally you won't have to constantly tune them or touch them at all.

⌨️ Has a lot of handy shortcuts (hotkeys): control video playback and extension settings without using a mouse (or eyes).

🕵️🚫 Does not track you or send your data anywhere. Fully local.

🆓🍺 Completely free, both as in "freedom" and as in "free beer" (at least for now):
Licensed under GNU Affero General Public License v3.0 or any later version (AGPL-3.0-or-later) — the most based license out there.
