Why Students Love It

Everything you need
to actually focus.

Three pillars that separate Lumina from every other YouTube tool.

01

Battery-Friendly Focus

Lumina stops your browser rendering parts you can't see, freeing real CPU power for the video and your battery during long study sessions.

02

Immersive Study Mode

Your notepad glows with the colors of your video. Blues for space docs, warm golds for lectures. It helps your brain enter a Flow State and stay there.

03

Your Personal Video Library

Close the tab. Come back next week. Notes are attached to that exact video — not mixed with everything else. You'll never lose a study note again.

/* One stack per video */

Focus Score

Awareness,
not judgement.

Think of it like closing your rings — but for your brain. Lumina tracks how focused you were and shows you a simple score at the end. No pressure, just progress.

Pause the video? Clock pauses too. Switch tabs? We notice. Come back? We pick up where you left off.

This is the extension I didn't know I needed. My lecture notes are so much better — I can actually keep up without losing my place.

Trust & Privacy

Your data never
leaves your machine.

Your notes stay on your device

Everything is saved locally. No servers, no cloud, no accounts. Even if we shut down tomorrow, your notes are safe — because we never had them.

Built to Chrome's highest standard

Lumina uses Manifest V3 — Chrome's latest, most secure format. It only activates on YouTube. Every other site is completely untouched.

We see nothing. We know nothing.

No analytics, no usage tracking, no crash reports. There is nothing to collect — by design. Lumina runs entirely inside your browser with no way to phone home.

Two permissions. That's it.

Lumina Pro

Master your attention.
Own your education.

The free tier is genuinely great. Pro is for people who've decided their learning time is non-negotiable.

Time is non-renewable

Pays for itself in one session

Lumina Pro reclaims the 20 minutes usually lost to the "suggested videos" rabbit hole. That's 120+ hours a year back in your hands.
