2025-01-13	Firefox user 12978919	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.
2025-01-08	Vít Janeček	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!

2024-10-17	Camryn2223	Works amazingly in 95% of cases. The 5% of cases it doesn't work in are YouTube and Twitch streams (it will constantly try to skip ahead if there's dead air but since it's live, the audio just sounds like the stream is skipping a bunch). If you could blacklist specific sites to not run it on(kinda like how uBlock Origin does) the issue with Twitch would be fixed, not sure how YouTube live streams could be handled though. I'd assume YouTube uses the same video player for both streams/videos so differentiating between a stream and video may be impossible for the developer but idk. EDIT: It seems the developer is aware of people wanting to blacklist sites as there have been suggestions for this feature on the extension's repo; however, it seems that Firefox makes it more complicated to do than Chrome.
2024-09-24	CoralDonkey	Works great on youtube, but it unfortunately doesn't seem to be able to recognise videos on echo360

2024-06-22	Firefox user 10290316	Works on youtube. And it works very smoothly. Better than I expected.
2024-03-25	JoeMuchen	Jump Cutter is the best product of its type that I have ever used. It skips silent passages very accurately. I can get the part I need in the video very quickly. Thanks to the developers, these work are great.

2024-02-14	Firefox user 18285282	Request new feature: Smoothed playback dynamic acceleration Example : 1- set desired speed e.g. x3 2- select starting speed e.g. x1.5 3- % of video passed until desired speed is reach e.g. 60% Result: The video begins at x1.5 increases gradually as a function of time based on the duration of the video by 60%, speed had gradually increased from 1.5x to 3x in 0.01 stepsizes. e.g. at 60% of elapsed video duration it will be playbackRate = x1.5 + (x3 - x1.5) (currentTime / duration) / 0.6 This formula means that the playback rate will start at x1.5 and increase linearly as a function of the current time divided by the duration of the video until it reaches 60% of the duration, where it will reach x3. This passive increase in cognitive load will lead to increased comprehension.
