VideoNoteGPT — YouTube Lecture Summarizer

Turn the YouTube video you are watching into AI notes, chapters, key terms and a quiz — in one click.

Watching a lecture on YouTube and want the notes without pausing every thirty seconds? Click the VideoNoteGPT icon while any YouTube video is playing. The extension reads the video's transcript in your browser and sends the text to VideoNoteGPT, which returns structured study material in a new tab — usually in under a minute. WHAT YOU GET FROM EVERY LECTURE - Chapter breakdown with timestamps — click a chapter, jump to that moment - Key points, each tagged with the time it was said - Key terms and definitions, sorted by difficulty - A full, searchable transcript - An AI quiz — 5 to 20 multiple-choice questions, graded, with explanations - Ask questions about the lecture and get answers from the full transcript EXPORT ANYWHERE - Anki (.apkg) — cards land straight in your collection - Obsidian and Notion (Markdown) - PDF study documents - SRT / VTT subtitles WHY THE EXTENSION RATHER THAN PASTING A LINK The transcript is read in your own browser, not by our servers. That is why it works where pasting a URL into a website does not. FREE TO USE No account needed. Your first lecture can be any length, up to three hours. After that the free tier covers lectures up to 45 minutes, three per day. WORKS IN 100+ LANGUAGES The extension uses the video's own transcript — English, Spanish, Hindi, Arabic, Bengali, and 90+ more. WHAT IT CANNOT DO Some uploaders turn transcripts off entirely, and private or age-restricted videos can't be read. For those, upload the file at videonotegpt.com and it will transcribe the audio itself. Privacy: https://videonotegpt.com/privacy Support: hello@videonotegpt.com
