After putting it off for weeks, I finally launched my extension today: It automatically captures slides from lecture videos
Hey everyone,
I launched SlideSieve on Product Hunt today. Honestly I've had the launch ready for almost a month but kept putting it off because I was nervous about putting my work out there. Finally hit the button today.
I take a lot of online courses on DLAI, Coursera, Udemy, YouTube, etc. Whenever I'm watching a lecture, I want to save the slides for later. The problem is that manually screenshotting kills the flow: you're constantly pausing, snapping a screenshot, trying to avoid catching the video player UI. And you still end up with a messy folder of images, or miss a slide and have to scrub back to find it.
That's the problem SlideSieve is meant to solve. It's a browser extension that runs in the background and captures slides automatically while the video plays, so you don't have to pause.
A few things I built into the capture logic to make it actually usable:
- Skips frames where the instructor's face fills the screen
- Ignores code, terminal windows, and dark transition screens, so it only grabs actual slides
- Exports everything as a clean, ordered PDF once you're done
Product Hunt has a lot of big platforms promising to change everything. This isn't that. It's not an AI "second brain," it won't take your tests for you. It's a small, focused tool to make studying a bit less annoying. There's a free tier to try it, and a one-time purchase for unlimited captures — no subscription, no cloud processing, everything runs locally in your browser.

Built this to fix my own studying mess. Nervous but glad to finally share it.
