Did we miss your pain point?
Write down the moment you felt most frustrated while doing math.
If it's a common pain point, we'll prioritize building a diagnostic engine for it.
Question Generation
The Personalized Medical Checkup Sheet
Minimalist Targeted Questioning
Abandon inefficient blind drilling. We use algorithmically calculated, minimal sets of targeted questions to efficiently scan and cover the boundaries of the core concepts you need to master.
| x | f(x) | f'(x) | g(x) | g'(x) |
|---|---|---|---|---|
| 1 | 3 | −1 | 2 | 4 |
| 2 | 5 | 3 | 4 | −2 |
| 3 | −2 | 7 | 1 | 6 |
f(x)g'(x) − f'(x)g(x)
Detection
Logic & Execution Diagnostic
Dual X-Ray of Logic & Execution
Complete your "checkup" on the system's digital paper. Our engine captures your derivation trajectory in real-time. We precisely isolate errors: Is it a surface-level execution slip or a deep-level logic fracture?
THE HANDWRITTEN
ADVANTAGE
Multiple-choice lets you guess. Typing hides your logic. Only your raw, handwritten steps reveal the exact point where your reasoning breaks down. We don't just grade the final answer—we diagnose your process.
LINE-BY-LINE EXTRACTION
We analyze your written sequence, isolating the exact line where a careless slip or a conceptual error occurred.
NO MORE "FAKE UNDERSTANDING"
Watching videos gives an illusion of competence. Forcing you to write out the proof exposes what you actually know.
ROOT CAUSE DIAGNOSIS
Pinpoint the exact foundational gap—like a missed 7th-grade algebra rule—that is sabotaging your current calculus problem.
Careless slip detected: The integral of sin(x) is −cos(x), not cos(x). Error starts at step 3.
