YouTube Lecture Summarizer — VideoNoteGPT

YouTube lecture → AI notes, chapters, transcript, quiz and Anki flashcards in one click. Free, no account needed.

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 caption track 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 caption request comes from your browser, not from our servers. That is why it works on videos where pasting a URL into a website does not. FREE TO USE No account needed. Three lectures a day, free, every day — any length up to three hours. WORKS IN 100+ LANGUAGES The extension picks the video's own caption track — English, Spanish, Hindi, Arabic, Bengali, and 90+ more. WHAT IT CANNOT DO Some uploaders disable captions 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.
