Formidable

Describe it. Formidable builds it.·formidable.software

Formidable is an AI-powered form builder that turns natural-language descriptions into dynamic forms with conditional logic, computed fields, and validation rules. Instead of a drag-and-drop UI, it generates a declarative form specification (Forma) that includes logic, calculations, and approval workflows built in. Forms can be published as hosted pages or rendered headlessly via a React SDK and REST API, with webhooks and analytics included.
