GoodMaith

GoodMaith is an AI math solver built around a live graph: as the tutor explains each step, the corresponding mathematical objects appear on the board — and it's a live construction, not a screenshot. You can drag points and watch related objects change, choose Teach mode (solved through step-by-step questioning) or Solve mode (full walkthrough drawn progressively), plus an exploration plotter and an interactive-graph handbook.

The "drag the tangent" moment is the product: static step-by-step solvers tell you the derivative; a draggable graph lets you feel what the derivative means. That's the difference between an answer machine and a teaching tool.

Who it's for: high-school and early-college students preparing for calculus-heavy exams, teachers who want interactive demonstrations for class, and parents whose math is rustier than their kid's homework. Free entry. The test is whether dragging actually couples to the explanation — try a problem where you genuinely misunderstand a concept and see if the graph makes it click.
