Welcome to Formidable

Formidable is an AI-powered form builder that helps you create dynamic forms through natural conversation.

What is Formidable?​

Formidable uses AI to transform your requirements into fully functional forms with:

  • Dynamic visibility - Show/hide fields based on user input
  • Computed values - Automatically calculate values from other fields
  • Validation rules - Ensure data quality with custom validation
  • Multi-page wizards - Break complex forms into manageable steps

Core Concepts​

FormSpec​

FormSpec is our declarative form specification format. It defines:

  • Field types and properties
  • FEEL expressions for dynamic behavior
  • Validation rules
  • Page structure for wizards

FEEL Expressions​

Formidable uses FEEL (Friendly Enough Expression Language) for dynamic behavior:

// Show field when age >= 18
visible: "age >= 18"

// Calculate total
expression: "quantity * unitPrice"
