Auto-Capture Course Slides into Clean PDFs

SlideSieve is a browser extension for Google Chrome and Microsoft Edge that acts as an AI-powered study assistant for your favorite online courses. Once installed, it runs in the background and analyzes video lectures in real-time. It automatically detects and captures presentation slides while intelligently skipping instructor webcam segments, code editors, and dark transitions.

SlideSieve is officially available for Google Chrome (via the Chrome Web Store) and Microsoft Edge (via Microsoft Edge Add-ons). It also works seamlessly on other Chromium-based browsers such as Brave, Opera, and Arc.

Currently, SlideSieve is fully optimized to work on DeepLearning.AI, Coursera, Udemy, and YouTube educational videos. It works seamlessly across these platforms to capture slides automatically. Support for additional platforms like edX and LinkedIn Learning is on our roadmap.

Yes. With SlideSieve Pro, you can automatically extract and save the full course transcript locally as you watch. You can view spoken text in real-time Timed View or clean Reading View, and export transcripts to TXT, SRT subtitles, or VTT format alongside your slides.

Yes, SlideSieve offers a generous free plan with no credit card required. You get our full AI auto-detection features with up to 50 slide captures in total. It's perfect for casual learners.

SlideSieve Pro Lifetime ($16.99) gives you permanent access with no expiration, unlimited slide captures per lesson, unlimited PDF exports, Slide Detection Zone & PiP Magic Eraser, course transcripts (TXT, SRT, VTT), multi-format export, and all future updates. It is a single one-time payment with zero recurring subscriptions.

For power users, SlideSieve supports quick keyboard shortcuts. Press Ctrl + Shift + 8 (or Control + Shift + 8 on Mac) to quickly toggle Auto-Capture on or off. To manually snapshot a specific frame instantly, use Ctrl + Shift + 9 (or Control + Shift + 9 on Mac). You can easily customize these shortcuts at any time by visiting chrome://extensions/shortcuts or edge://extensions/shortcuts in your browser.

Yes. Click the Manual Capture button on the floating toolbar, or use Ctrl + Shift + 9 (Control + Shift + 9 on Mac) to instantly save the current frame. If auto-detection skips a frame you need, you can also use the Slide Detection Zone: draw a rectangle over the slide area to tell SlideSieve exactly where slides appear. This is the cleanest fix for courses with a persistent instructor webcam overlay or a split-screen layout.

Auto-Capture automatically pauses if you switch to another tab or minimize the window, as browsers restrict background video analysis. Keep the course tab active for continuous capture. Capture resumes instantly when you return—no slides are lost.

Yes. The Slide Detection Zone and PiP Magic Eraser (available on Pro) are built for this. Many courses use a Picture-in-Picture (PiP) layout: a small instructor camera window floats in the corner of the video, overlaid on the slides. With Pro, click the Detection Zone icon on the SlideSieve toolbar, drag to draw a rectangle over the slide area (or exclude the camera overlay), then click Save Zone. You can even enable PiP Magic Eraser to seamlessly fill in the obstructed slide content. The zone saves per course, so you only set it once.

SlideSieve's interface is fully localised in 15 languages: English, German, French, Spanish (Spain and Latin America), Italian, Portuguese (Portugal and Brazil), Japanese, Korean, Simplified Chinese, Traditional Chinese, Indonesian, Hebrew, and Turkish. Your language is auto-detected when you install the extension and can be changed at any time from the Settings panel.

Yes, completely. All video analysis and slide processing happen entirely on-device within your browser using our local AI. No video frames, slides, or personal data are ever sent to our servers. Your captured slides are stored safely in your browser's local storage.
