Psychology 101
Searching lectures and notes
Classical conditioning links two stimuli so that one begins to trigger a response. Operant conditioning links a behavior with a consequence, making that behavior more or less likely to happen again.
Answers stay tied to selected sources
If the selected materials do not support a claim, ClassLecture is designed to make that gap clear.
Sample content and source labels show the workflow; they are not a live answer or accuracy guarantee.

Start Asking Course-Specific Questions in 3 Steps
Create a class and add materials
Record or upload lectures, then add the notes, slides, PDFs, and textbooks from the same course.
Choose what to search
Ask across lectures, notes, or both, and narrow the conversation to a specific source when you need to.
Get an answer you can verify
Read a course-specific response and open the supporting lecture timestamp or document page for context.
Stop searching one file at a time
Your lectures and notes belong
in the same conversation.
Answers are harder to find when recordings, slides, notes, and textbooks live in separate places. ClassLecture lets you search the sources for one class together.
Search across the class
Ask one question across the lectures and documents you select instead of opening every source yourself.
Check the original source
Open the cited lecture timestamp or document page when you want the professor’s wording or more context.
See when evidence is missing
Use clear source boundaries to identify gaps in your uploaded materials instead of treating every response as equally supported.

Questions About Chatting With Course Materials
Choose the sources behind each conversation and move from an answer back to the material your professor provided.
What course materials can I chat with?
You can ask questions about recorded or uploaded lectures, notes, PowerPoint slides, PDFs, Word documents, EPUB textbooks, and other supported class files.
Can ClassLecture search lectures and documents together?
Yes. In class chat, you can choose lectures, notes, or both. You can also narrow the search to a particular lecture, document, or chapter.
Where do the answers come from?
Answers are grounded in the class materials you select. Citations can take you to the relevant lecture moment or document page so you can check the source yourself.
