Lecture Chat
The Lecture Chat lets you ask questions about a specific lecture while you are viewing it. Iris uses the lecture slides and transcripts to give answers grounded in the actual material.
How to Access It
When viewing a lecture in Artemis, click the floating Iris icon in the bottom-right corner of the screen. The chat opens alongside the lecture content.
What Iris Can Reference
Iris has access to the materials associated with the lecture you are viewing:
- Lecture slides — the slide deck uploaded by the instructor
- Transcripts — if the lecture has a recorded video, the transcript of the spoken content may also be available
When Iris uses these materials to answer your question, it includes citation markers in the response. Hover over a citation to see exactly which slide or transcript segment it came from. For more on how citations work, see How Iris Helps You Learn.
Example Use Cases
- "Can you explain what the instructor meant on slide 12 about polymorphism?"
- "Summarize the main points of this lecture."
- "What is the relationship between the topics on slide 5 and slide 18?"
- "I didn't understand the example about binary search trees. Can you walk me through it?"
How It Differs from Course Chat
| Lecture Chat | Course Chat | |
|---|---|---|
| Scope | One specific lecture | All lectures and materials in the course |
| Best for | Questions about what you are currently viewing | Broader questions across the course |
| Access | From within a lecture view | From the course sidebar |
Use Lecture Chat when you want answers tied to a specific lecture. Use Course Chat when your question spans multiple topics or lectures.
