Falcon AI
AI for Grasshopper
Native Grasshopper plugin: chat with Claude to create Rhino geometry or GhPython scripts. No Python server, runs inside the plugin.
- Rhino Viewport Mode: geometry appears directly
- GhPython Script Mode: copy code into Script component
- Claude, GPT, Ollama: multi-provider support
- Runs locally in Rhino 8, no external server
- Free tier available

Describe
Type what you want in natural language: "Create a parametric facade with hexagonal cells that respond to solar exposure."
Generate
AI selects the right Grasshopper components, wires them together, sets initial parameters, and builds a working definition.
Refine
Tweak sliders, ask for changes in plain text, or let AI analyze your definition and suggest improvements. Iterate until perfect.

Get Falcon AI
Free tier: download from Food4Rhino. Install the .gha plugin directly. Requires Rhino 8 (Windows) and an Anthropic API key.
$ Download .gha from Food4Rhino → Copy to Grasshopper Libraries folder → Restart Rhino Frequently Asked Questions
What is Falcon AI?
Falcon AI is a native Grasshopper plugin (C#) that lets you chat with Claude or other AI models to create Rhino geometry and GhPython scripts. It runs inside Rhino, no separate Python server required.
Do I need coding experience?
No. Describe what you want in plain English (e.g. "Create a 10m box at origin" or "Tower 10 floors, 5m base"). Falcon AI generates geometry or GhPython code for you. Advanced users can refine the output.
Which Grasshopper plugins are supported?
Falcon AI works with native Grasshopper components. GhPython mode generates code that can use Ladybug, Honeybee, Kangaroo, and other plugins. We're expanding support with each release.
Is it safe to use with client projects?
Your prompts are sent to your chosen AI provider (Claude, GPT, etc.). Your Rhino geometry and project files stay on your machine. The plugin runs locally; only the text of your prompts goes to the API.
How do I install Falcon AI?
Download the plugin from Food4Rhino. Copy the .gha file to your Grasshopper Libraries folder (File → Special Folders → Components Folder). Restart Rhino 8, open Grasshopper, search for 'Fraktal' and drag the component. First run: Settings → enter your Anthropic API key.
Early Feedback
“Falcon AI saved us weeks of Grasshopper wiring on a complex parametric facade. The AI understands what architects mean.”
“I've been scripting GH components for years. Falcon AI generates better definitions than most junior programmers.”
“The open-source approach won us over. We deployed it across our office in a day.”
