About this extension
Meet Mono - the tired little robot who tidied up your YouTube so you didn't have to. Don't bother thanking him. He'll probably ignore you.

This is a lightweight browser extension that strips YouTube down to the essentials by hiding recommendations, distractions, and dark patterns with pure CSS. No JavaScript, no tracking, no background processes.

Reclaim your time.

Features:
- Blocks YouTube homepage recommendations
- Removes sidebar and navigation menus
- Hides YouTube Shorts shelves
- Removes end cards and end-of-video autoplay recommendations
- Removes subscribe and download buttons
- Removes comment input (comments remain readable)
- Disables channel links
- Centres the video player

Lightweight CSS-only extension - no JavaScript, no tracking, no background processes. Works on all YouTube pages including watch, search, and homepage.
