YouTube Bookmarker

A lightweight Chrome extension that lets you bookmark, rename, delete, replay, and take notes on any timestamp in YouTube videos — perfect for learners, content creators, and anyone who wants to revisit important moments with ease.

This project demonstrates key concepts in DOM manipulation, Chrome Extension APIs, and Chrome Storage, along with industry-standard version control using Git.
