Add-on summary

Analyze keywords

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

Video demo

🌐 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).

A great tool for listening to lectures! Be prepared for the vast amount of knowledge you'll encounter in the same time—it's going to be immense.

First I tried buying CaryKH's official version, only to find out it's abandonware and I've thrown out my 5 bucks. Then I tried his free original script, which just didn't work (understandable, it was a proof of concept). I was ready to abandon hope, when, like Moltres* you've caught at your door, this version appears. Edit: alternativeto is actually how I eventually found you! I just didn't know about it then. But thank you! Moltres is a pokémon I wildly misspelled. The phrase is from a Chalkeaters song. Edit 2: Just found out the dev's "contribute" link links to a charity, what an actual bro!
