Edulab is a Claude Code plugin that takes a math or geometry problem as input and produces a self-contained HTML page that you can open in any browser. The page shows a step-by-step written solution on the left side and an interactive 3D model on the right side. You can rotate and zoom the 3D shape, and the camera moves to highlight the relevant elements as you follow the steps. The first skill included is called edu-solid-geometry, which handles solid geometry problems: things like finding the angle between a line and a plane, the angle between two planes (a dihedral angle), the angle between two lines that do not intersect, or the distance from a point to a plane. It works on shapes like cubes, cuboids, pyramids, prisms, cylinders, and cones. You can give it a problem as text, upload a photo of a problem, or ask it to generate a random one. Under the hood, the computation is done by a Python library called sympy that performs exact symbolic math rather than approximate floating-point arithmetic. This means the coordinates, vectors, and final answer are all derived from the same calculation, so the written steps and the 3D model always match. The output is a single HTML file that packages everything: the math rendering (using MathJax for formulas), the 3D visualization (using Three.js), and the solution steps. You can install it with one command through the skills package manager or through the Claude Code plugin marketplace. It can also be run from the command line without Claude at all, using Python scripts that build example pages for common shapes like cubes and cuboids. The project is Apache 2.0 licensed. Adding support for new problem types or new solid shapes is documented in the repository and requires editing two Python files.
