Runchat has won us time by making it faster to generate renders from Rhino and helping the team collaborate on image-making workflows.

It helps us iterate on concepts for sculptures while generating colour strips, automating unrolls and laying out cut files for fabrication.

For agents

Bring Runchat to your own agent

The Runchat CLI connects Claude Code, Codex or any agent with a terminal to your canvases, models and tools. Sign in once in the browser; no API keys to paste.

Create and control Grasshopper definitions

The free Runchat agent works directly inside Grasshopper. Ask it what any component does, have it dial in slider values, read and write geometry to Rhino, and build definitions from native components and plugins.

Analysis

Quick wind comfort and solar gain studies on early massing options.

Build consistent, reusable tools for your team

Publish any workflow as a tool that can be reused on the canvas or by the design agent. Tools can help define style guides and simplify complex workflows or design processes.
