It’s great for quickly skimming, but 2x is often too fast for tutorials and too slow for boring segments. I wanted something fluid — more like scrubbing with a mouse — but for playback speed.
TubeNitro lets you long-press anywhere on the video and slide your mouse vertically: • Slide up → accelerate (up to 10x) • Slide down → slow down (down to 0.5x)
The speed changes continuously and shows a small overlay so you can see the exact rate.

Yet another image converter when Squoosh and ImageOptim already dominate this space.
Synthesizes modem sounds via Web Audio API instead of loading external audio files.
It grabs tab audio via the screen-capture flow and runs it through WebAudio nodes — convolution reverb with selectable IRs, a dB-style bass boost, and playback/pitch controls — all in the browser. Clever, because it sidesteps extension APIs and DRM limitations by using getDisplayMedia, so you get real-time effects on ordinary web players; snagging reliable system/tab audio is the neat technical trick here. Expect some UX friction (you must share the tab and enable 'also share tab audio'), but the core idea is satisfying and immediately usable.
Auto-press Enter after voice dictation saves prompt review time.
Yet another AI playlist tool when YouTube and Spotify already do this.
