I built PodTube, a Chrome extension for listening to YouTube podcasts, lectures, and music. I wanted the audio. The screen had other plans.

What I built

A headphone button and Shift+A shortcut to toggle the listening mode.
Video blur and automatic lower video quality while audio keeps playing.
Playback-speed controls alongside YouTube’s player.

I built the extension with TypeScript and Manifest V3 and published it on the Chrome Web Store. The official site has the walkthrough and install link.
