What is Glasp?

Glasp is a video notes tool. A free browser extension and web tool that summarizes YouTube videos with ChatGPT, Claude, Gemini or Mistral, showing a clickable timestamped summary and full transcript beside the player. The same panel handles articles and PDFs, and highlights export to Notion, Obsidian and Markdown.

Glasp's YouTube Summary is a browser extension that puts an AI-generated summary and a full timestamped transcript next to the video player instead of in a separate tab. It combines four model options (ChatGPT, Claude, Gemini and Mistral) behind a single panel, and it extends the same treatment to web articles, newsletter posts and PDFs opened in the browser. The site also offers a paste-a-link summarizer that works without an install or an account, which makes it easy to test the output quality before committing to the extension. The workflow is built around checking rather than blind trust. Key points carry timestamps, so clicking one jumps the player to that second in a 45 minute talk. The transcript sits in a parallel pane in any language YouTube supplies captions for, and it can be copied in one click or highlighted line by line with notes. Summary length, number of key points, the model and the output language are all user-controlled, and the output language can differ from the spoken language of the video. Highlighted passages export to Notion, Obsidian, Roam Research and mem.ai, or download as Markdown, HTML, CSV or JSON. Chat is the second layer. On a video, answers cite transcript timestamps; on an article or PDF, the panel answers in your own words and can build on highlights you have already saved. Chat requires a free Glasp account and the Free plan carries 20 credits per month at one credit per question, with paid tiers adding credits plus Balanced and Deep model options. It suits students working through lectures, researchers triaging long interviews and knowledge workers who clip sources into a notes system. Against single-model summarizers such as NoteGPT or Eightify, the differentiators are model choice, cross-format coverage and the highlight-and-export pipeline; against pasting a transcript into ChatGPT manually, it removes the copy step. Anyone who mainly watches on a phone is better served by the Glasp mobile app, since the browser extension does not run there.

    The Free plan includes 20 Chat credits a month at one per question. Paid plans add credits and the Balanced and Deep models.

Pros and cons
