Watching on your phone?
The Glasp app summarizes any YouTube video on your phone — transcript, summary and chat in one place.
A free browser extension that summarizes YouTube videos, web articles and PDFs with ChatGPT, Claude, Gemini or Mistral. On YouTube it puts the summary and the full transcript beside the video — timestamps you can click, a transcript you can copy or highlight, and exports to Notion, Obsidian and Markdown. This page will summarize a video without installing anything: paste the link above.
Install YouTube Summary on Chrome, Edge or Firefox, then open any YouTube video. The summary widget appears beside the player.
Choose ChatGPT, Claude, Gemini or Mistral and get the key points in seconds — with timestamps you can click to jump to that moment.
The full transcript sits beside the video in the language you choose. Copy it in one click, or highlight the lines worth keeping and export them to Notion, Obsidian or Markdown.
Pick the model, the length and the number of key points. The summary comes back in seconds, in the language you choose — not necessarily the one the video is in.
The on-page summary is timestamped. Click a key point and the player jumps to that second, so a 45-minute talk can be checked in five.
Read along beside the video or copy the whole transcript in one click, timestamps included. Available in every language YouTube has captions for.
Highlight lines of the transcript, add a note, and export to Notion, Obsidian, Roam Research or mem.ai — or download as Markdown, HTML, CSV or JSON.
The same extension summarizes web articles and PDFs, so one install covers what you read as well as what you watch.
