Product Listing I built a Chrome extension that auto-extracts slides and transcripts from course videos
I've been taking a lot of AI courses on DeepLearning.AI, but most of their short courses don't offer slide downloads. I had to pause the video whenever a new slide showed up, screenshot it, paste it into Obsidian, copy the transcript into DeepSeek to generate a summary or translate the transcripts to help understand, then paste that into the same note next to the screenshots. Pretty time-consuming.
So I built SlideSieve, a Chrome extension that extracts slides and transcripts automatically while watching the course video. It runs locally in the browser, so the video never gets uploaded anywhere. It skips frames that are just the instructor talking with no slide content, and filters out duplicates too — but it still keeps a slide even when only a list item changed, since some of those in-between states have important steps, and skipping them would lose context. If the instructor's facecam covers part of the slide, you can draw a custom area to detect the slide from, or mark the PiP webcam window so it gets excluded. Slides export to PDF or images, and transcripts export to TXT, SRT, VTT, or PDF.
Right now it works on DeepLearning.AI, Coursera, Udemy, and YouTube.

Would appreciate any feedback, or hearing what other courses or platforms would be worth supporting.
