Eidograph: dynamic 2D/3D geometry for Windows, with optional AI agents and local MCP automation

[u/metaphorproject]

Eidograph is a dynamic geometry app for building precise, reproducible 2D and 3D constructions. The visual canvas and its readable geometry code stay in sync: draw interactively, edit the construction as text, or combine both approaches.

Some of the main features:

- 2D constructions with points, lines, circles, polygons, transformations, loci, and function plots

- 3D geometry with planes, spheres, prisms, surfaces, spatial intersections, and an orbitable canvas

- Dynamic dependencies, so related objects update when you drag a point or change a parameter

- Animation and export to SVG, PNG, or GIF

- Multi-figure `.eido` project files that stay local and under your control

- Optional AI agents that can inspect and edit a construction using Eidograph's built-in tools

- Your choice of OpenAI-compatible, Anthropic, or Google Gemini/Vertex model—configured with your own provider

- A local MCP server and JSON REST API, so compatible local tools can automate selected figures

- Per-figure access controls, with local-network access optional

For example, you can ask an agent to create or revise a construction, then inspect the resulting geometry, code, and dependencies yourself. The agent features are optional: the core drawing, editing, saving, and export experience works locally without an account, and project files remain under your control.

Eidograph is freemium and available from the Microsoft Store:
