AI form builder that turns plain-language prompts into high-converting conversational forms
Describe the form in plain language and the AI builds the full field structure, question wording and multi-step flow for you.
Replace intimidating long forms with one-question-at-a-time flows that are easier to finish on mobile.
Add branching, skip logic, calculated fields and conditional follow-ups through a visual editor.
Review submissions, partial responses and drop-off points to see where people abandon the form.
Open-source form builder with AI assistance and unlimited responses
The full codebase is public and auditable, and you can run OpnForm on the vendor cloud, an EU-hosted instance, or your own infrastructure for complete data ownership.
Optional AI help for building forms and fields, designed to stay out of the way when you would rather write everything yourself.
Conditional logic, computed fields, answer piping, hidden fields and redirect-on-submit rules let one form adapt to many different respondents.
Collect as many responses as you need even on the free plan, with no hidden quotas or surprise overage charges.
