How It Works
A daily learning loop that stays calibrated to your frontier
01
Take the diagnostic
A 10-minute adaptive assessment finds exactly where you are. Smart questions skip what you already know and zero in on your frontier.
02
See your brain bricks
Your knowledge map lights up. Each brick is a concept. Colors show subjects. Golden bricks mean true mastery.
03
Learn adaptively every day
Spaced repetition picks what to review. The AI tutor adjusts from full explanations to Feynman-technique challenges based on your mastery.

FAQ
Questions future learners ask before they join
What subjects does Cerebryx cover?
Six tracks: Math Foundations, Advanced Math, ML Foundations, LLMs & Applied AI, Reinforcement Learning, and MLOps & Systems. Each track has 60-120 concepts with prerequisite-aware sequencing.
How is this different from Brilliant or Coursera?
Cerebryx adapts to you. The diagnostic maps what you already know in 10 minutes, then every session starts exactly where your gaps are. Spaced repetition ensures you actually retain what you learn — not just watch videos.
How long should I practice per day?
Most learners see results with 15-30 minutes of focused practice. The spaced repetition algorithm handles scheduling — it picks what to review and when.
Can I use this for interview prep?
Yes. The Pro+Interview tier includes mock interviews, applied systems practice, and company-specific preparation tracks.
When does the app launch?
We're currently in development. Join the waitlist to be notified when we launch on iOS, Android, and web.
