Studying from YouTube? Add the free extension

YouTube blocks our servers from reading captions, so a pasted link can’t work. The extension reads them in your own browser instead — one click on any captioned video, and the notes come back here.

Get the Chrome extension →

Free, and no account needed. Works on Chrome, Edge and Brave.

Notes, transcripts and flashcards for every kind of lecture

Record in class or upload what you have. VideoNoteGPT turns it into chapters with timestamps, key terms, a full transcript, a quiz and flashcards.

Lecture recordings

Zoom, Panopto and Echo360 recordings, phone voice memos and in-class audio become structured notes you can search.

Summarize a lecture recording

YouTube lectures

The free Chrome extension reads a video's captions from your own browser, so a YouTube lecture can be turned into notes too.

Video to transcript

Turn an MP4 or MOV into a transcript with timestamps, then copy it or export it as text, SRT or VTT.

Video transcript generator

Quizzes

Multiple-choice questions written from your own lecture, so you practise on what your course actually covered.

AI quiz generator

Exam season

Slides or a lecture become flashcards and a practice exam, so the night before a midterm is spent practising instead of rereading.

Midterm rescue

For students, teachers and researchers. Also works on podcasts, and you can listen to your notes as an audio recap.
