Online Course Lectures
Find any topic in a lecture without rewatching it
Recorded lectures are a study lifeline, but a single course can hold dozens of hours of video, and the one explanation you need for tomorrow's exam is buried somewhere inside. SearchByVideo lets students search lectures by spoken content and on-screen text—type "where the professor derives the equation" and land on that exact moment. Instructors use the same search to locate segments for review, build clips, and point students to precise timestamps. Studying becomes targeted instead of a hopeless rewatch of everything.
SearchByVideo lets students and instructors search course lecture videos in natural language to find the exact moment a topic, formula, or example is explained. Instead of scrubbing an hour-long lecture before an exam, describe the concept and jump straight to where it was taught.

"Before finals I used to skim three hours of lecture just to re-find one explanation. Now I type what I'm stuck on and SearchByVideo takes me right to the minute the professor covered it. It changed how I study."
