Simple by design

Learning made effortless

Three steps from download to your child's first lesson — and you're in control the whole time.

1
🎯

Set your child's profile

Create a profile with a nickname and your child's birth month and year. Pick the subjects they love and set a daily screen time limit. Lumen Kids builds a personalised feed that matches exactly what they need to learn.

2
✨

AI curates the perfect feed

Every video is scored across 12 quality dimensions by our AI — pacing, visual calm, teaching clarity, age-appropriateness. Only the best make it through.

3
📈

Watch them grow — literally

After every video, a quick quiz reinforces what they learned. You get a weekly summary of subjects covered, scores and conversation starters for bedtime.

The Lumen Kids standard

We measure what actually matters

Not likes, not comments, not view counts. Our AI analyses the real signals that determine whether a video genuinely teaches — or just keeps kids glued to a screen.

✓
What makes the cut
What our AI scores positively
✓
Slow, deliberate speech Measured in words per minute — not guessed. Calm, clear narration that gives children time to absorb.
✓
Calm, purposeful visuals Simple animations that support the lesson — not compete with it for attention.
✓
Concept repetition and reinforcement Key ideas revisited multiple times so children actually retain what they hear.
✓
Participation prompts "Can you say it with me?" — the hallmark of content designed to teach, not just entertain.
✓
Voice louder than the music Background music should support the narrator — not drown them out.
✕
What gets rejected
Automatic disqualifiers — no exceptions
✕
Talking too fast Rapid speech leaves no processing time. Our AI measures exact words per minute — automatically rejected above threshold.
✕
Flashing or strobing visuals Overstimulating effects that hijack attention and suppress active thinking.
✕
Screaming or high-energy presenters Loud, excitable hosts condition children to need constant stimulation just to stay engaged.
✕
Hyper-fast scene cuts Rapid editing is an engagement trick, not a teaching tool. Our AI detects and rejects it.
✕
Music overpowering the voice When background music dominates, children follow rhythm — not meaning.

🔬

We don't count likes, comments or views.

Most "curated" kids apps use popularity signals — likes, view counts, watch time. We don't. A video with 500 million views can still damage your child's attention span and teach them nothing. We analyse actual content — word by word, frame by frame — using multimodal AI that reads what a child sees and hears. Popularity is not quality. We measure quality.

What's inside

Every video, rigorously vetted

We score each video on content accuracy, teaching pace, visual calm and age-appropriateness. No toy unboxing. No screaming. No brain rot.

About the company

Built by Lumenix Labs

Lumenix Labs is an independent software studio building tools that put learning before engagement. Lumen Kids is our first product — born from a simple frustration: the platforms our kids spend the most time on are designed to keep them watching, not help them learn.

We use AI to do what humans can't do at scale — review thousands of educational videos against a strict pedagogical rubric, and only pass the ones that genuinely teach. Then we get out of the way. No ads. No engagement loops. No tricks. Just calm, well-paced lessons and a quiet quiz to check what stuck.

We collect the absolute minimum data needed to run the service. We never sell it. We never target ads at children. Read our Privacy Policy and COPPA Notice — they say exactly the same thing the app does.
