You watch tutorials. You feel like you learned. Then you forget.
ChatGPT teaches but doesn’t remember
You explain the same context every session. It starts fresh every time.
Reading feels like learning
Until you try to recall it cold. Progress bars lie; so does nodding along.
No one knows what you actually know
Self-reports are optimistic. The test is the only honest signal.
How it works
Prove you know it. Keep it forever.
Three steps. No fluff, no re-reading, no forgetting by next week.
Ask any topic
Type anything — a concept, a question, a full subject. The AI teaches it clearly, from first principles to real examples.
Prove you know it· the difference
Answer a quick 5-question test. No shortcuts — score 75%+ and it counts. Below that, nothing is stored.
Watch your brain grow
Pass the test and a new node lights up in your brain — permanently connected to everything it relates to.
Your knowledge — proven, mapped, yours.
Every topic you master becomes a node. Connected to everything it relates to. Honest about what you know and what still needs work.
What makes it different
Memory-aware teaching
The tutor reads your existing brain before every lesson — connecting new topics to what you already know, instead of explaining everything from scratch every time.
Test-gated knowledge
Nothing enters your brain on vibes. The server scores every test and decides what gets stored — solid, faint, or nothing at all.
A visual brain map
Every proven topic is a node. See what you know, at a glance.
Connections between topics
Supply & Demand ↔ Inflation ↔ Monetary Policy. The graph draws the lines the tutor reasons about, so you can see how the ideas in your brain actually fit together.
Tutorials are forgotten. Chatbots are conversations.
claratto is the third thing: knowledge you've proven, kept forever.
Tutorials & chatbots
You watch, you nod, you move on. Nothing is stored. Next week, it's gone.
