Summarize Your Lecture in 3 Steps
Record or upload a lecture
Capture class in your browser or upload an existing audio or video lecture recording.
Let ClassLecture process it
Your recording becomes a searchable transcript that can support a focused AI summary.
Review and keep asking
Read the summary, choose the format that works for you, and ask follow-up questions about the lecture.
Stop replaying the whole class
Find the important ideas.
Keep the original lecture close.
A full recording preserves everything, but it is slow to review. A focused summary gives you a faster starting point while the transcript and audio remain available.
See the lecture’s structure
Review key ideas in organized sections instead of searching through an hour-long recording from the beginning.
Return to the original moment
Use the searchable transcript and recording when you want the professor’s complete wording or surrounding context.
Continue with follow-up questions
Ask about a confusing concept in the same workspace instead of treating the summary as the end of your review.
