Hi Product Hunt! 👋

I built Lumina because I was tired of "5-minute coding tutorials" turning into 2-hour rabbit holes thanks to the YouTube sidebar algorithm.

A Quick Maker’s Update: Even before our official launch today, Lumina has started climbing the charts organically! I've been tracking our "wild" stats, and the momentum is real:

  • +2,600 spots jumped in the Education category this week.

  • Top 200 ranking for "Tutorial" keyword searches.

  • 100% Retention: We’ve hit 26 total installs with 0 uninstalls this week—once users go Zen, they stay Zen.

Most "study" tools are either too heavy or require a monthly subscription. I wanted something lean, red, and "Zen." I’m excited to finally share the "Zen Upgrade" with this community!

I’ll be here all day to answer questions. What’s the biggest distraction that stops you from finishing a lecture?

Hey Product Hunt! 👋 I’m Oussama, the maker of Lumina.

We’ve all been there. You open YouTube for a 5-minute coding tutorial, and two hours later, you’re 40 videos deep into a rabbit hole.

The YouTube algorithm isn't broken; it is a masterpiece of attention engineering. Willpower simply isn't enough to beat a multi-billion dollar AI designed to keep you clicking. I built Lumina because my own study sessions were getting hijacked, and I needed a way to turn YouTube from an entertainment trap into a focused e-learning platform.

Today, I’m incredibly excited to launch Lumina v3.0 (The Zen Architecture). We completely rebuilt the extension from the ground up.

Here is what makes v3.0 special:

  • 🛑 Repaint Suppression (Eco-Engine): We don’t just visually hide the sidebar; we physically stop your browser from rendering it. This saves massive amounts of GPU and battery life during long study sessions.

  • 📝 Smart Note Stacks: The floating notepad now auto-organizes your notes by Video ID and Channel. No more messy text files.

  • 🎯 Focus Score: A real-time, gamified attention tracker that rewards you for staying on task.

  • ✨ Zero-Flicker Performance: A new debounced observer engine makes the transition into focus mode buttery smooth.

  • 🔒 100% Local & Private: Your notes and focus scores live on your device. No cloud, no servers, zero data tracking.

I built this to solve my own problem, but seeing 100% retention with our early users made me realize how widespread this issue is.

I would absolutely love your feedback. How do you currently handle distractions when trying to learn on YouTube? What features would make Lumina even better for your workflow? I'll be hanging out in the comments all day to answer questions! 🎓👇
