Turn any YouTube video into visual notes

Caddie is a YouTube video summarizer that gives you notes, not just a summary. Paste a YouTube or X link and you get notes chapter by chapter, with a visual that explains each idea, while you watch with the transcript following along. Zoom from the gist to every detail, ask it anything about the video, and share the notes as a page. It works in your browser and in the Mac app.

Free while in beta, then $10 a month for everything in Caddie.

How it works

1. Paste a link. Any YouTube or X video, in a new note.
2. Watch, or don't. The transcript follows along as the video plays.
3. Read the notes. Chapter by chapter, with visuals, from the gist down to every detail; ask anything; share it as a page.

Notes you can zoom

Start with the gist in a few lines, then zoom into notes per chapter, then every detail with timestamps. Each chapter gets a visual that explains its idea, so you can skim a two-hour podcast in five minutes.

Ask the video anything

Ask a question about the video and get an answer from what was said.

Keep it with your other notes

Video notes are ordinary Caddie notes: searchable, in your folders, next to your meeting notes and tasks, and readable by your AI agents through Caddie's MCP server.

Share as a page

Send anyone a link to the notes; they don't need Caddie to read them. Our growth library is hundreds of podcast episodes shared this way.

Other ways to summarize a YouTube video

YouTube's own "Ask" answers questions on some videos in some countries; NotebookLM can add a public video with captions as a source; extensions like Glasp and Eightify put a summary beside the video. Caddie is for when you want notes you keep, with visuals, from YouTube and X.
