Why use SlideSieve for Udemy?
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 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
Many Udemy instructors use picture-in-picture webcam overlays. SlideSieve's spatial blob detection identifies and skips frames dominated by instructor faces, even when the webcam is in the corner of the slide.
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 covers your first 3 lessons (up to 50 slides each). Pro ($16.99, lifetime) unlocks unlimited captures across all courses.

Yes. SlideSieve works on all Udemy courses and automatically captures presentation slides from lecture videos. It filters out instructor webcam footage and code editor windows so you only get genuine slide content.
Can SlideSieve capture slides from Udemy programming courses?
Yes, for the slide content. SlideSieve uses a code-frame veto filter (horizontal line density analysis) to automatically skip IDE windows, terminals, and browser DevTools — capturing only the presentation slides in your course.
Does SlideSieve work on Udemy courses I purchased?
Yes. SlideSieve works on any Udemy course you have access to. It operates on the video player inside your browser, so it works with personally purchased courses, team plans, or Udemy for Business accounts.

What happens if I pause the Udemy video?
SlideSieve only captures frames when the video is actively playing. Pausing the video also pauses capture. When you resume, SlideSieve continues monitoring from where it left off — no slides are missed.
SlideSieve captures slides for personal study use only. Please respect the intellectual property of Udemy instructors and course creators.
