Video Segment Highlighter Chrome Extension

📌 Video Segment Highlighter – Save, Highlight & Take Notes on YouTube Videos

Ever watched a long YouTube video and wished you could save just the important parts instead of bookmarking the whole thing?
With Video Segment Highlighter, you can instantly highlight key sections, add personal notes, and revisit them anytime — all directly on YouTube.

🌟 Why this extension?
YouTube playlists and watch later queues are great, but they don’t solve the real problem:
👉 In long lectures, tutorials, podcasts, or interviews, you only care about specific timestamps, not the entire video.

Video Segment Highlighter fixes this by letting you:
-Highlight the last 30s, 45s, 1m, 1.5m, 3m, or 5m with one click
-Add custom time highlights (in minutes)
-Attach personal notes to each highlight (study notes, reminders, quotes, key points, ideas)
-See highlights as yellow markers directly on the YouTube timeline
-Open a draggable notes panel while watching to view all your notes in one place
-Review, edit, delete, or export your highlights from the extension popup
-No more rewatching entire videos just to find that one useful part.
