What is SmartHopper
Imagine having an AI assistant that actually understands your Grasshopper definitions.
That's SmartHopper - a groundbreaking plugin that lets AI peek into your canvas and lend a helping hand (or algorithm).
AI That Actually "Gets" Grasshopper
Unlike other AI tools, SmartHopper is fully integrated in Grasshopper. It converts your Grasshopper definitions to JSON and feeds them directly to AI models. This means the AI can understand your parametric logic, suggest improvements, and even help reorganize components. It's like having a super-smart colleague who never gets tired of your questions!
Work natively with your data
AI deeply integrated into your work! SmartHopper provides innovative components that process Grasshopper data natively. Integrate them into your workflow to accomplish tasks that were previously impossible. From sorting and filtering lists based on natural language prompts to generating text tags that suit your needs!
Connected to McNeel Forum
The chat is connected to McNeel Forum. When you ask a question, SmartHopper will automatically search for similar questions and provide you with the best answers. Actually, it's like talking to the full community in seconds!
Ready for complex data trees
SmartHopper components handle complex data trees seamlessly. They automatically match branches across all inputs using the same path structure. When an input only receives a single path, SmartHopper intelligently applies it to all other paths, ensuring consistent data flow.
Compatible — customizable
Why be locked into one AI provider? SmartHopper supports OpenAI, MistralAI, and DeepSeek APIs, with more coming soon. Switch between ANY available model based on your needs, budget, or just curiosity. Each AI has its own personality and strengths - find your favorite!
