SlideSieve — Auto Slide Capture & PDF Export

Auto-capture lecture slides from any online video course as PDF. Skips instructor webcam. Smart deduplication. 100% private.

Save lecture slides from Coursera, Udemy, YouTube, and DeepLearning.AI — automatically, as a clean PDF, with zero manual screenshots. SlideSieve watches your video, identifies every real slide frame, and exports them into a perfectly organized, multi-page PDF. Smart image analysis filters out talking-head instructor segments, dark transitions, and near-identical duplicates so you only get the slides — nothing else. Works with YouTube, Udemy, Coursera, and DeepLearning.AI. More platforms coming soon. ✨ Key Features: 🎯 Auto Slide Detection Identifies genuine slide frames across any course style or platform — no configuration needed. Works with different video layouts, aspect ratios, and slide designs automatically. 🚫 Instructor Frame Filter Skips any frame where the instructor's face dominates the screen, including picture-in-picture overlays and full webcam segments. Only real slide content is captured. 🧹 Smart Deduplication Never end up with 50 copies of the same static slide. Subtle text additions, bullet-point builds, and progressive reveals are still captured reliably. 📸 Manual Snap Instantly capture any specific frame with a single click — perfect for moments you want to save regardless of auto-detection. 📄 PDF & Image Export Compile all captured slides into a clean, multi-page PDF — or export them as individual images. Each slide preserves its original aspect ratio exactly as it appeared in the video. 🗂️ Course-Scoped Storage Slides are automatically organized by course and lesson, stored locally in your browser. Nothing is uploaded anywhere. 🔒 100% Private All captured slides are stored entirely on your local device. SlideSieve collects no personal data and transmits nothing to external servers. 📚 Perfect For: - Students saving lecture slides from Coursera, Udemy, or DeepLearning.AI courses - Anyone building PDF study notes from YouTube educational videos - AI and ML learners who want to capture slides from fast-paced technical courses - Anyone tired of pausing and screenshotting videos manually 📋 How to Use: 1.
