Building a form used to mean starting from a blank canvas: adding fields one by one, wiring up logic, and fiddling with layout until it looked presentable. An AI form builder flips that process. You describe the outcome you want ("a job application form with a resume upload") and the AI generates the questions, field types, and page structure for you. You review, adjust, and publish.
This guide walks through the whole process using Formly, an AI form builder with a full editor underneath. The same principles apply to any prompt-based form tool.
Open Formly and describe your form in plain language. The quality of the prompt shapes the quality of the draft, so it's worth spending thirty seconds on it. A good prompt covers three things:
Some examples:
You don't need to list every field. That's the point. Describe the outcome and let the AI propose the structure.
The AI gives you a complete first draft: questions, field types (email, phone, rating, multiple choice, file upload, signature, and so on), and pages. Before you publish, read it the way a respondent would:
In Formly, the generated form opens in a normal drag-and-drop editor, so you can rewrite questions, reorder pages, and restyle everything. If you'd rather iterate by prompt, you can also tell the AI what to change, like "add a 1–5 rating question", and it edits the form for you.
For anything longer than a handful of questions, two features make a real difference to completion:
You can ask for these in the original prompt ("split it into two pages, and only ask for a phone number if they choose 'call me back'") or add them in the editor afterwards.
Once the form looks right, publish it and put it where your audience already is:
A form is only useful when the answers reach the right place. Set up webhooks to push every submission into your CRM, database, or automation tool the moment it arrives, or pull responses through the REST API. If you use an AI agent like Claude or ChatGPT, you can even connect it over MCP and ask it to fetch and summarize responses for you. See our guide on building forms with AI agents.
Do I still need to know form design? Less than before, but the fundamentals still pay off: our form design best practices cover what to check before publishing.
Can I start from a template instead? Yes. Formly has ready-made templates for common use cases like feedback surveys, job applications, and event registrations, and you can customize any of them.
What does it cost? Formly has one plan: Pro at $29/month (or $24/month billed annually) with unlimited forms and submissions. Cancel anytime (see pricing).
