Did you know you can highlight YouTube video transcripts directly in your browser?
With Glasp’s free browser extension, you can highlight, copy, and save specific parts of YouTube transcripts—so you can capture key ideas without rewatching entire videos.
In this tutorial, you’ll learn how to highlight YouTube transcripts step by step and turn video content into organized notes you can revisit anytime.
👉 How to Highlight YouTube Videos

Please open any YouTube video you like. Then, you can see Highlight on Video at the top right of the screen. When you click that section, it opens the transcript of the YouTube video.

If you successfully log in, you can see a popup to highlight a sentence when you select the sentence. Then, please click any color you want. It highlights the sentence you choose.
If you cannot highlight the sentence, please check the login status by clicking the Glasp icon on the toolbar.

If you click the Glasp icon on the toolbar, it shows the sidebar. And you can see all the highlights and notes you made in this YouTube video.

If you click other languages, you can see the transcript in other languages.
If you click the copy-content button (red square), you can copy all the transcripts and paste them anywhere such as Notion, Obsidian, Evernote, Apple note, etc.

After highlighting the transcript on YouTube, you can visit your profile page to see all the highlights and notes.
To do so, please click the Glasp icon on the toolbar and click your profile icon at the top right of the sidebar.

If you go to your profile page, it shows all the highlights & notes from the YouTube video. And clicking the timestamp (Ex: 03:23) opens the original YouTube video and starts playing from that time (Ex: 03:23).

Also, you can add notes, delete highlights, and share the highlights by clicking the three dots next to the highlights.

Even if you don’t sign up for Glasp, you can use the Glasp extension and copy the transcript of the YouTube video. So, please install and try it out.
A quick and easy way, isn’t it? In just one platform you can now easily view, access, and edit your YouTube highlights and notes — it is certainly possible with Glasp and YouTube!
