What is Glasp?
Glasp's YouTube Summary is a free Chrome extension that lets you quickly access transcripts of YouTube videos, summarize them using AI, and ask questions about the video content. Powered by OpenAI's ChatGPT (GPT-3.5, GPT-4), Anthropic's Claude, MistralAI, and Gemini, the tool condenses longer videos into short, readable summaries with timestamps so you can quickly understand key points without watching the entire video.
Key features include: AI-powered video summaries with clickable timestamps that jump to corresponding video parts, full transcript access with copy functionality, YouTube Q&A that extracts common questions about the video topic and provides concise answers, support for multiple AI models, language selection for transcripts, keyboard shortcut support (Ctrl+X+X or Command+X+X), follow-up prompts that auto-apply after summaries, and customizable summary prompts. The extension also integrates with Glasp's highlighting system, allowing you to save and highlight important transcript sections.
This tool is perfect for students who want to learn faster from educational videos, researchers extracting key insights from long lectures, productivity enthusiasts managing information overload, content creators researching topics, lifelong learners consuming YouTube content efficiently, and anyone who wants to retain knowledge without spending hours watching videos. With over 200,000+ life-long learners using Glasp, it's designed for anyone who wants to make YouTube content more accessible and useful.

Frequently asked questions about Glasp
How do I use YouTube Summary for free?
Transcript Copy is available up to 5 times per day for free on the standard YouTube Summary extension. You can extend this limit by switching to a different browser since each browser has its own separate 5-copy quota per day. For unlimited free transcripts with no daily cap, use Glasp Reader which lets you copy transcripts freely with no preset prompts and no limits.
What AI models power the YouTube Summary?
The summarization functions are powered by multiple AI models including OpenAI's GPT-3.5, GPT-4 (ChatGPT), Anthropic's Claude, Mistral AI, and Gemini. You can choose which AI model to use for generating summaries.
Can I customize the summary prompts?
Yes, you can customize prompts for both the Article and YouTube Summary extensions. This feature allows you to optimize your prompts to make more accurate or expected summaries. You can also add follow-up prompts that automatically apply after generating a summary without needing to retype them each time.
How do I access transcripts on YouTube videos?
When you visit YouTube videos with the Glasp extension installed, you'll see a gadget box on the top right where you can quickly access transcripts. Click 'View AI Summary' to see the summary with timestamps. If you cannot see transcripts, it means YouTube doesn't provide them for that video, or you may need to wait a minute if the video was recently uploaded.
Can I use YouTube Summary without preset prompts?
Yes, there are two ways: Option 1 is using Glasp Reader which lets you copy transcripts freely with no preset prompts and no daily cap (completely free). Option 2 is using the Glasp extension which also supports YouTube Summary without any preset prompts. You can install both extensions alongside the YouTube Summary extension.
What browsers support the YouTube Summary extension?
The YouTube Summary with ChatGPT & Claude extension is available for Chrome, Microsoft Edge, Safari, and Firefox. You can install all three Glasp extensions (Glasp Web Highlighter, YouTube Summary with ChatGPT & Claude, and YouTube Summary & ChatGPT by Glasp) at the same time to maximize your free transcript limits across browsers.
Can I highlight YouTube transcript sentences?
Yes, after creating a Glasp account (sign up via Google or Apple Sign-in), you can select sentences on the YouTube transcript and click any color from the popup to highlight them. Your highlights appear in the sidebar when you click the Glasp icon, and you can view them on your 'My Highlights' profile page with timestamps that jump to the video.
Is there a keyboard shortcut for summarizing videos?
Yes, you can use the keyboard shortcut Ctrl+X+X (Windows) or Command+X+X (Mac) to summarize any YouTube video, webpage, or PDF instantly. This works even on YouTube's updated UI that may block the usual summarize button. You need to enable shortcut keys in both the YouTube Summary extension and Glasp Chrome extension settings.
What is YouTube Q&A feature?
YouTube Q&A extracts the most common questions asked about a video topic and provides clear, concise answers to each one. This feature complements the summary and transcript by giving you direct answers to questions you might have about the video content without needing to ask manually.
Can I use Glasp in Incognito mode?
Yes, you can use the Glasp Chrome Extension in Incognito mode, but you need to enable 'Allow in Incognito' in your Chrome extension settings. Visit the tutorial 'How to Use the Glasp Chrome Extension in Incognito Mode' for detailed steps.
