Glasp is a free browser extension that lets you highlight web articles, PDFs, and Kindle books—and save your highlights in one place.
Instead of losing important ideas across tabs and platforms, Glasp helps you collect, organize, and export what you read into tools like Notion, Obsidian, or Markdown files.
In this guide, you’ll learn how to install the Glasp browser extension and start highlighting in just a few minutes.
Step 1: Sign up for Glasp

Step 4: Start highlighting on a web page
Once the Glasp extension is installed, you can start highlighting any web page you read.
Open any article or blog post on the web.
Select the text you want to highlight.

The highlighted text is saved automatically to your Glasp profile.
You can also add notes or comments to your highlights to capture your thoughts while reading.
💡 All highlights you create on web pages will appear on your Glasp profile page automatically.
Step 5: Review your highlights on your profile page
After highlighting a web page, return to your Glasp profile page to review your saved highlights.
Open your Glasp profile page.
Refresh the page to make sure your latest highlights are displayed.
Find the article you just highlighted.
Your highlights are saved automatically, so you don’t need to click a save button.
💡 If you don’t see your highlights right away, try refreshing the page.
Step 6: Add notes, comments, and tags to organize your highlights
Once your highlights are saved, you can add context and structure to them on your profile page.

Find the Thoughts & Comments section at the top of the page.
Click the input field labeled “Leave your thoughts, findings, etc.”
Write your overall thoughts or summary about the article.

You can add tags to a highlighted article from your Glasp profile page to categorize and organize your highlights.
Open the highlighted article on your Glasp profile page.

Step 7: Manage your highlights and articles
You can manage your highlights and articles directly from your Glasp profile page.
Delete a highlight
You can delete an individual highlight in two different ways.
Both methods remove only the selected highlight.
Option 1: Delete a highlight from the popup

Use this option when you want to remove the article and all highlights associated with it.
Open the article on your Glasp profile page.
Click the More options (⋯) menu next to the article title.
Select Delete.
This removes the article and all of its highlights at once.
💡 Deleting an article cannot be undone.

If you select Private, you’ll be prompted to upgrade your plan.
