Education
Students and educators can transcribe lectures, seminars, and office hours. Ask AI to explain concepts, generate study guides, or find where a specific topic was discussed.
How it works
Record the lecture
Upload audio or video from class, or paste a link from your LMS or recording platform.
Get the transcript
Full lecture transcript with speaker labels — professor, students, guest speakers all identified.
Study with AI
Ask questions about concepts, generate study notes, or find exactly where a topic was covered.

Introduction to ML — Lecture 4
Based on the lecture:
- Optimization algorithm that adjusts parameters to minimize loss
- Learning rate controls step size — must balance speed vs. accuracy
- Prof. Chen used the analogy of rolling a ball downhill to find the lowest point
Gradient descent adjusts model parameters to minimize the loss function. Think of it as rolling a ball downhill.
The learning rate determines step size. Too large and you overshoot the minimum, too small and training stalls.
How do we know when the learning rate is too high?
What you get
Concept Q&A
Ask AI to explain any concept from the lecture. It answers using the actual content, not general knowledge.
Study guide generation
Auto-generate summaries, key takeaways, and structured notes from any lecture recording.
Topic search
Find exactly where a topic was discussed, across all your lectures. Jump to the timestamp instantly.
- Lecture transcription with speaker labels
- AI-powered Q&A about lecture content
- Searchable study material library
- Export notes in multiple formats
Example
"Explain the difference between mitosis and meiosis based on today's lecture" — AI answers from the transcript.
