Scale the highest peaks of human knowledge
— one step at a time.
Cordelet is a personal AI tutor for any topic. Name a summit and it works out what you already know, then teaches you all the way up to the edge of current research.
Log in to start — your climber’s logbook follows your account across every summit.
How it works
Pick a summit
Any topic — consciousness, AGI, or whatever you want to understand. Cordelet maps a learning path from the fundamentals up to the frontier.
Climb by conversation
Cordelet asks you questions, finds where your understanding breaks, and teaches you from there — keeping a logbook of how you think.
Reach the frontier
At the top it doesn't fake a tidy ending — it hands you the real open problem and the honest approaches researchers are taking on it, so you come away genuinely up to date. From there you can branch off and climb one of those.
Summits to climb
A few of the grand open problems you can take on — or bring your own.
- Mathematics
Riemann Hypothesis
A 160-year-old pattern in the primes that no one can prove — math's most famous open problem.
- Physics
Quantum gravity
Our two best theories of reality contradict each other. Uniting them is physics' deepest quest.
- Biology & Medicine
The origin of life
How did lifeless chemistry on the early Earth cross the line into living, replicating cells?
- Biology & Medicine
The basis of consciousness
How does three pounds of brain tissue produce the felt experience of being you?
- Biology & Medicine
The molecular basis of aging
Is aging an inevitable wearing-down, or a program we could one day slow or reverse?
- Computer Science
Artificial general intelligence
Can a machine match the full, flexible breadth of human thought — and how would we know?
- Earth & Cosmos
Are we alone in the universe?
Is life a cosmic fluke or a near-inevitability? The answer reshapes our place in everything.
- Foundations & Philosophy
Do we have free will?
Are your choices truly yours, or the inevitable output of physics and neurons firing?
- Foundations & Philosophy
Why is there something rather than nothing?
The deepest question of all — why does a universe exist at all, instead of nothing?
