Video Segment Highlighter

Save and highlight important sections of YouTube videos right on the timeline.

📌 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. ✨ Key Features 🎬 Highlight important sections directly on the YouTube timeline Click preset buttons (30s → 5m) or enter a custom time -Saves the last N seconds from the current play position -Highlights appear as yellow bars on the progress bar 📝 Add notes instantly -Attach a note to the most recently created highlight -Notes are tied to your highlights, making it easy to recall why you saved a section -Hover over a yellow marker to see your note or use the floating Notes panel 📒 Draggable Notes Panel -Open a floating panel that lists all notes for the current video -Fully draggable and resizable -Click any note to jump back to that exact section 📂 Extension Popup Management -Click the extension icon to open the popup -View all highlights for the current video with times + notes -Edit or delete highlights -Export all highlights + notes as JSON for backup or sharing -Clear all highlights with one click 🔄 Works seamlessly with YouTube navigation -Handles YouTube’s single-page navigation (no need to reload) -Works with normal videos, Shorts, playlists, lectures, and livestream replays 💾 Safe & simple storage -Highlights and notes are stored in Chrome Sync Storage -Your data stays private and follows you across devices if Chrome sync is enabled -No external accounts or logins required ⚙️ Customizable, minimal UI -Floating panel is compact, light gray with draggable positioning -Collapse toggle for distraction-free viewing -Timeline highlights are clear but non-intrusive yellow -Notes panel is lightweight and unobtrusive 📚 Perfect for: Students – Save the exact moments in lecture videos where concepts are explained Professionals – Highlight training sessions, webinars, and conference talks Researchers – Collect quotes, data points, and references from long discussions Content creators – Bookmark inspiration, examples, or techniques Podcast listeners – Save the golden moments in 2+ hour discussions Anyone who takes learning seriously on YouTube 🚀 How to use: -Install the extension -Open any YouTube video -Use the floating panel to create highlights -(Optional) Add notes to your highlights -Revisit highlights directly on the timeline or via the Notes panel -Manage everything from the popup
