TubeMargin: Notes & Transcript for YouTube

Turn YouTube videos into notes you keep. Transcript with timestamps, your own ChatGPT, Claude or Gemini, Markdown for Obsidian.

Turn YouTube videos into notes you keep. TubeMargin adds a panel to YouTube's right-hand column, or below the player in theatre mode, never on top of it. Read the YouTube transcript, click any timestamp to jump there, and send it to your own ChatGPT, Claude or Gemini with a clean prompt. Then keep the result as Markdown for Obsidian or Notion. YOUR AI, YOUR NOTES, NOTHING ADDED • We never add anything to your prompt. What you send is what you chose. • No analytics, no tracking, no sign-up for the free features. • Your notes live in your browser. We run no server that receives your videos or transcripts. FREE, WITH NO DAILY LIMIT • YouTube transcript with clickable timestamps • One-click hand-off to ChatGPT, Claude or Gemini, in your own account • Four prompts: summary, faithful notes, study notes, key quotes • Copy or download as Markdown, .txt or .srt PRO, FOR PEOPLE WHO BUILD A LIBRARY • Frame screenshots placed in your notes at their timestamp • A searchable library of every video you save • Your own custom prompt templates • Bulk export of your notes as Markdown files with an index Monthly, yearly or one-time lifetime.

If a transcript is too long for the AI you pick, TubeMargin splits it into clearly numbered parts or warns you. It never silently cuts it. GOOD TO KNOW • Works on videos that have captions or a YouTube transcript. Videos without either are not supported yet, and TubeMargin tells you. Shorts and live streams are not supported yet. • You need your own account at the AI site you choose. SCREENSHOTS Screenshots use the video "Can I Use This?
