Auto-Capture Udemy Course Slides into Clean PDFs
SlideSieve is a browser extension for Chrome and Edge that automatically captures presentation slides from Udemy course videos while you watch. It distinguishes between slide frames and instructor talking-head footage, extracts the full course transcript, and exports everything as a clean, organized PDF — with no manual screenshots and no upload required.

Why use SlideSieve for Udemy?
Tailored detection algorithms designed specifically for Udemy lecture video layouts and study workflows.
Works on all Udemy courses — any subject
SlideSieve supports Udemy courses in every category: programming, design, business, photography, music, and more. Any course video that plays in your Chrome or Edge browser is supported.
Smart code-frame veto for programming courses
Programming courses spend a lot of time in code editors and terminals. SlideSieve's horizontal line density analysis automatically detects and skips IDE windows, so you only capture the actual slide presentations.
Instructor webcam filtering & Detection Zone
Many Udemy instructors use picture-in-picture webcam overlays. SlideSieve's AI skips frames dominated by instructor faces. For persistent corner webcams, simply draw a Slide Detection Zone to tell the extension exactly where to look or what to ignore.
Save Udemy Transcripts
SlideSieve automatically extracts and saves the full course transcript alongside your slides. You can search for specific topics and export the transcript for comprehensive study notes.
Handles Udemy's animated slide transitions
Udemy's slide transitions can cause a burst of near-duplicate frames. SlideSieve's binarized structural diff algorithm waits for the transition to settle and captures only the fully resolved slide.
Organized by course and lesson
SlideSieve groups captured slides by Udemy course and lesson name, so your exported PDFs are clearly named and easy to navigate even across a long multi-section course.
No upload, no cloud, no subscription
All processing is local. Your video content and captured slides never leave your browser. The free plan lets you capture up to 50 slides in total and includes a 1-time transcript extraction trial. Pro ($16.99, lifetime) unlocks unlimited captures and transcripts across all courses.
How to Save Lecture Slides as a PDF
Extract slides and transcripts in a few simple steps.
Install Extension
Add the SlideSieve Chrome extension to your browser. The tool runs alongside your video player.
Open Video Lecture
Navigate to a supported course platform and open a lecture video. The SlideSieve toolbar appears below the video player.
Set Detection Zone (Optional)
If your course has a persistent instructor webcam (Picture-in-Picture) over the slides, draw a Slide Detection Zone over the slide area to ignore the camera.
Capture Slides
Click Start Auto-Capture, then play the video. The extension analyzes the frames and extracts presentation slides. It captures presentation slides and diagrams, and skips instructor-only shots and transitions. For code walkthroughs, press Manual Snap (Ctrl+Shift+9).
Review Captured Slides
Access your saved slides in the side panel. View them in a grid, list, or presentation view, and delete any unwanted frames.
Export PDF & Transcripts
Generate a PDF document of your slides and optionally export the full course transcript. Read or print your study guide offline.
