In their own words
Formidable
Formidable is a cloud form builder that generates forms from natural-language descriptions. Conditional logic can show, hide, or require fields based on answers and expressions. Computed fields evaluate in real time for weighted scores, boolean outcomes, and formatted outputs. Business rules can produce approve, reject, or escalation outcomes. Users can publish hosted forms, share links, embed forms in an iframe, and receive submissions through webhooks. A JSON REST API and the open-source Forma React library support custom interfaces. Account, form, and submission data are stored in the European Union. Generation prompts may be processed by Anthropic, while submission and respondent data are not sent to AI services. The Free plan costs nothing and includes one published form, 1,000 submissions per month, conditional logic, computed fields, webhooks, analytics, and a one-time AI-token allowance. Starter costs $15 a month; Pro costs $49 a month. Submissions beyond a plan limit are not accepted until the next billing cycle unless upgraded.
