MatHud lets you draw and manipulate geometric objects - points, segments, vectors, polygons, circles, ellipses, and angles - directly on an interactive canvas, while an AI assistant solves algebra, calculus, trigonometry, statistics, and linear algebra problems with LaTeX-formatted explanations. You can plot functions, compare intersections, shade bounded regions, translate and rotate objects, visualize probability distributions and bar charts, and fit regression models (linear, polynomial, exponential, logarithmic, power, logistic, sinusoidal) with R² statistics. The tool also supports graph theory structures like trees and DAGs, workspace management for saving and resuming projects, Vision mode for sharing your canvas with the assistant for feedback, and built-in client-side testing.
