YouTube Highlights

Capture and manage highlights from YouTube videos while you watch. Mark the moments that matter, add notes, and export them for later.

Note This extension is not affiliated with YouTube and is not the YouTube Studio highlight feature. Check our website for more info.

The Problem

YouTube is full of valuable content, but finding that one quote, concept or moment you remember from a video you recently watched can be a pain. Scrubbing through hours of content to rediscover a 30-second insight is not a good use of your time.

This extension lets you mark those moments as you watch, so you can come back to them without the hunt.

What You Can Do

• Create highlights while watching YouTube in Arc browser. The extension captures the current timestamp and a configurable duration before it.
• Add notes to your highlights for context.
• View all your highlights in chronological order or grouped by video.
• Search through your highlights by text or video title.
• Export highlights to Markdown, JSON, or CSV.
