Learn the method, not only the answer
Visible steps
See coefficients, the discriminant and substitution checks for supported equations, or request a structured AI explanation.
Honest limits
AI answers can be wrong. The interface separates deterministic local checks from model-generated explanations.
Connected practice
Move from a worked result into practice, flashcards and a private notebook.
Private worksheet flow
Images and selected PDF pages are sent to the AI service only after email sign-in and an explicit solve request.
