HOW IT WORKS
From idea to skill in four steps
MEET LUX
Your AI learning guide. Not an answer machine.
Lux coaches you like the best tutor you've ever had: it asks questions before giving answers, gives the smallest nudge that moves you forward, and treats your mistakes as learning signals.
It distinguishes between not knowing a fact (needs information) and not understanding a concept (needs coaching) — and responds differently to each.
What's your current understanding of how gradient descent works in neural network training?
It adjusts the weights to minimize the loss function?
That's the goal, yes. Here's a tighter question: what specifically gets updated during each step, and how does the learning rate factor in?
The weights get updated in the direction opposite to the gradient, scaled by the learning rate.
Exactly. Now — what happens when your learning rate is too large? What do you think you'd observe during training?
Frequently asked questions
Do I need to know what I want to learn before I start?
Not at all. You can start with a broad topic like "machine learning" or a specific goal like "I want to understand how transformers work well enough to explain them in a job interview." Lux will ask a few questions and build a path from there.
How is RokSpark different from watching YouTube tutorials?
YouTube is passive — you watch, you might absorb some of it, but there's no practice and no feedback. RokSpark keeps you active: every lesson includes exercises, your mistakes generate coaching responses, and you're building real skill rather than familiarity with content.
What subjects can I learn on RokSpark?
The "Learn Anything" feature lets you explore any topic — from AI and coding to photography, leadership, sales, biology, woodworking, or anything else. Structured courses created by educators are available for specific subjects and programs.
How does Lux know when I'm stuck vs. when I just need more time?
Lux monitors your responses during exercises. If your answer shows a conceptual gap (you have the wrong model of how something works), Lux asks questions to surface and correct it. If your answer is just incomplete, Lux nudges you toward the full answer. The coaching adapts to what your specific response suggests about your understanding.
Is there a free plan?
Yes. You can start for free with $5 in AI credits. Paid plans add more monthly credits, unlimited learning journeys, and access to the full course catalog.
