SlideSieve: Auto Slide Extractor & PDF Export for Video Courses

Automatically detects and captures high-quality slide frames from video courses. Skips instructor faces. Exports clean PDFs.

SlideSieve is a smart slide extraction tool for online learners. It automatically captures high-quality lecture slide frames directly from video courses — filtering out talking-head instructor frames, dark transitions, and near-duplicate frames — and compiles only the best slides into a clean, multi-page PDF. Works across popular learning platforms including YouTube, Udemy, Coursera, and more, with special optimization for DeepLearning.AI courses. ✨ Key Features: - 🎯 Auto Slide Detection: Intelligently identifies slide frames using structural image analysis — not just screenshots. - 🚫 Instructor Frame Filter: Automatically skips frames showing the instructor's face or talking-head camera segments. - 🧹 Smart Deduplication: Removes near-identical frames so you never get 50 copies of the same static slide. - 📸 Manual Snap: Instantly capture any specific frame with one click. - 📄 PDF Export: Compile all captured slides into a clean, multi-page PDF — each slide preserving its original aspect ratio. - 🗂️ Course-Scoped Storage: Slides are organized by course and lesson, stored locally in your browser using IndexedDB. - 🔒 100% Private: No data ever leaves your device. 📚 Perfect For: - Students taking courses on DeepLearning.AI, Coursera, or Udemy - Anyone studying from YouTube lecture videos - Learners who want clean, organized course notes without manual screenshots 📋 How to Use: 1.
