# Nexus

> Cosmon's AI agent for engineering — connected directly to your CAD and simulation tools.

## What is Nexus?

Nexus is an AI agent that works directly inside your engineering software. It understands your designs, runs your simulations, and helps you move from concept to validated design faster — all through natural language.

Connect Nexus to SolidWorks, Ansys, COMSOL, Abaqus, or Star-CCM+ and start working the way you think, not the way your software was designed.

Work with it interactively in the app, or drive the same agent from your own Python with the [Agent SDK](/sdk/overview) — to batch, script, and embed it in your pipelines.
