Lecture2Notes

Lectern is a tool that transforms long-form video lectures into readable book chapters, blog posts, or study guides. It transcribes the lecture, organizes spoken ideas into a coherent written narrative, selects relevant teaching frames, and links each passage back to its exact timestamp in the original video. The review workspace keeps the article, chapter outline, and source video synchronized, allowing users to verify citations, revise generated prose, and export the result as timestamp-linked Markdown. A built-in version of Andrej Karpathy’s tokenization lecture demonstrates the workflow without requiring API credentials.
