Highlight PDF and Websites, save it for later, and share it with everyone.
Glasp is a PDF & Web highlighter that helps you collect and organize your favorite quotes and thoughts from the web. You can also access other like-minded people’s learning and build your AI clone from your highlights and notes.
"Glasp Web Highlighter: PDF & Web Highlight" is a free Chrome Extension that lets you quickly highlight websites and PDF files with colored highlighting options, which are then automatically curated to your Glasp homepage. These highlights can then be tagged, searched for, linked to, and shared on a variety of other platforms, including Twitter, Teams, and Slack. YouTube, web article, and PDF summarization functions are powered by AI models such as ChatGPT (OpenAI), Claude (Anthropic), Mistral AI and Gemini.
You can see all the highlights and notes in the sidebar on the web and PDF, and clicking each highlight takes you to the highlighted place in the web page or inside the PDF. Also, you can tag the web page and PDF and see what other people highlighted in the website or PDF from the sidebar. With one click, the content you’ve collected appears across all your devices!
Check out your highlights on your Glasp page or in the original source, where they remain highlighted. Discover more content on the Glasp website and connect with other like-minded readers who share your interests. By following your friends or like-minded people, you will discover insightful and thought-provoking content that deepen your knowledge and understanding.

- (2025-07-06) Dan Lopez: MASSIVE time saver! I use Glasp only for YouTube video transcripts but honestly it has changed the way I consume content. I am able to copy and paste them into my AI models for insights, without having to spend the time watching the videos, get highlights, insights, etc. I am able to consume a lot more content and learn a lot more, more quickly, because of this app/extension. I do a lot of AI training at work and with partner agencies and I always mention Glasp as one of the most important tools in my AI learner's toolbox.
- (2025-07-03) Farzad T: The Glasp plugin is great at summarizing YouTube videos and interacting with various AIs. I really appreciate the development team for this useful and smart tool

- (2025-06-24) Dorien Morin-van Dam: I am using Glasp in my 'Video to blog' workflow, and it's fantastic! Easy to use, shows up instantly and is accurate (enough) for AI to read and use as the basis for an article.

Try the Glasp Audio Transcriber for quick, easy transcriptions and summaries. ------ This is happening to ALL VIDEOS now
- (2025-06-10) Gab Ree: This app is getting through the process of enshitification. i used it for the last year, it was free and was working all good. now it breaks, doesn't show youtube transcripts or shows them after 3 page reloads ,and then ridiculously asks for more money if use that function which connects my chatGPT account to do some prompt on the transcript. It worths paying chatGPT , but not for your app that is only a click to copy paste the transcript into chatGPT. Basically a new free app will replace you. i just uninstalled glasp.

- (2025-05-08) no-reply: What would be the actual advance of Grasp after many evolutionalized faster evolutionally than the ancient IT's "Dog Years" Grasp can capture the lightning-speed, massive-magnitude and full-spectrum evolution in huge amount of Gen AI? They are still accelerating the evolution of widening, deepening and piercing functionalities, increasing self-motivators with internal batteries, full-featured free AI suites, free for use, self-motivated full-spectrum abilities with Internal batteries. Grasp can compete with just one same core of the latest Gemini 2.5 Pro in Google AI Studio and NotebookLM Plus by Google and Deep Mind? This pair show off some functionalities similar with Grasp, as you know. Also, Grasp could absorb and align them as it own.
- (2025-05-08) Maytaphinan Choto: the best
- (2025-05-08) rui J: Thank you very much for encountering this plugin. But can the border on the right side be adjusted manually? It's really annoying to keep covering the content of the web page.🫠

- (2025-04-19) Bojan Latinovic: This is not just a highlighting app. It's a lot more than that. Here's one minor suggestion. It would be helpful to enable a drag-and-drop function for highlights, allowing us to position related highlights next to each other. If I highlight a text related to a previous highlight, I can drag and drop the highlight next to it.
- (2025-04-19) biranchi rout: its good

- (2025-04-17) Crystal Rocha Torres: I'm loving this extension. It's making my referencing video content extremely more efficient. Thank you for collaborating with Notion!!
- (2025-04-09) hasa hasa: Great tool, but some problems on tags. When I add highlights on a page, and add a tag (such as USA) to that page, and I go to the glasp dashboard, that tag (USA) will not show up in the tag position on the bottom left side of the dashboard, and when I search for the tag (USA) in the search bar of the dashboard, the page will not come up. And，I want to save the page with the highlights: I can add highlights and export the highlights to an md file; I can add bookmarks, but I can't export the bookmarks to an md file. So, I can't export the md file of the page containing the highlight. Is there any way to solve this problem?
