Transforming how students learn from video lectures
Every day, millions of students spend countless hours manually screenshotting lecture slides from recorded videos. It's tedious, time-consuming, and takes valuable time away from actual learning.
LectureHarvest was built to solve this problem. We believe students should spend their time understanding concepts, not clicking screenshot buttons. Our platform automatically extracts every unique slide from video lectures with precision and speed, giving students more time to focus on what matters: learning.
LectureHarvest emerged from recognizing a universal frustration across classrooms worldwide. As educational content shifted online, students faced a new challenge: extracting valuable slide content from hours of recorded lectures.
Existing solutions were either too simplistic—producing hundreds of duplicate frames—or too restrictive, offering no control over quality and extraction settings. We knew there had to be a better way.
Built with modern web technology and advanced algorithms, LectureHarvest processes videos entirely in your browser, ensuring complete privacy while giving you unprecedented control over the extraction process.
Your videos never leave your device. All processing happens locally in your browser, ensuring your academic content remains completely private.
Unlike one-size-fits-all tools, we give you full control with quality presets, frame intervals, similarity thresholds, and presenter masking options.
Built for speed without compromising quality. Our optimized algorithms ensure fast processing while maintaining high-quality slide extraction.
We're committed to removing barriers to effective learning. Every feature is designed to give students more time to understand, not manage, their study materials.
LectureHarvest leverages cutting-edge browser technology to deliver a powerful, privacy-focused experience. Our platform uses WebAssembly and advanced JavaScript APIs to process videos entirely client-side, meaning no upload delays, no server processing costs, and complete data privacy.
Our intelligent duplicate detection algorithm uses perceptual hashing and similarity scoring to identify unique slides with remarkable accuracy, while our presenter masking technology can detect and remove webcam overlays from lecture recordings.
Start extracting slides from your lectures in minutes, not hours.
