Antforms (also known as ant forms or ant form) is an AI form builder that lets you create and edit forms using natural language. Instead of only dragging blocks, you can describe what you want—surveys, feedback forms, contact forms, quizzes—and the AI helps build and refine them. Industry trends in 2025–2026 show AI form builders allowing users to create forms by describing needs in plain language, eliminating manual setup and coding; forms can be refined through conversational AI (e.g. “collapse empty sections” or “add tooltips”). Here’s how Antforms works and what features you get.

What is an AI form builder?
An AI form builder uses a conversational assistant to create and update forms. You describe the form or the next question; the AI adds the right question types, options, and settings. You still have full control: you can edit, reorder, or remove anything the AI creates. Modern form builder platforms support conditional logic without code—branching, field dependencies, and workflow automation—so the AI form builder isn’t just a generator; it works within a full form builder software stack.
Antforms combines this AI assist with a full visual builder, so you can use either the chat interface or the block editor—or both. That makes it both a free AI form builder (no paywalls on core creation) and a best form builder option for teams who want speed without sacrificing conditional logic or form analytics.
Antforms AI form builder — main features
1. Natural-language form creation
- Describe your form — e.g. “Create a customer feedback survey with an NPS question and a comment box.”
- Add questions by description — e.g. “Add a star rating for satisfaction” or “Add a multiple choice with options A, B, C, D.”
- Update and refine — “Make question 2 required” or “Change the thank-you message.”
The AI maps your intent to the right question types and settings and applies changes via the builder. This AI form generator approach speeds up creation for contact form builders, NPS survey designers, and feedback form creators who don’t want to configure every block by hand.
2. Rich question types (AI can add any of these)
- Text: Short text, long text (e.g. comments, feedback)
- Choice: Multiple choice (single or multiple), Yes/No
- Input: Email, phone number, website URL
- Numbers and ratings: Number, star rating, opinion scale (e.g. 0–10), NPS
- Dates: Date, scheduler (e.g. meeting booking)
- Other: Statement (instructions/headers), rank, signature, file upload, matrix
- Composite: Contact info (name, email, phone, company), address
So whether you’re building a contact form, NPS survey, quiz, or feedback form, the AI can suggest and add the right blocks. As an online form builder, Antforms supports the question types most teams need for lead capture, surveys, and events.
3. Form settings (AI can update)
- Title and description
- Appearance — Primary color, background color, font
- Thank-you message and redirect URL after submit
You can say things like “Set the button color to blue” or “Change the thank-you message to …” and the AI updates the form settings. This keeps the form builder experience consistent whether you use chat or the visual editor.
4. Publish and unpublish
- Publish — Make the form live (shareable link). The AI only publishes when the form has at least one question.
- Unpublish — Take the form offline (responses are kept).
So you can go from “create a feedback form” to “publish it” in one flow, then unpublish when you want to edit. As a best free form builder, Antforms doesn’t cap the number of forms or responses on the core tier.
5. Full form state (getFormState)
The AI can read the current form—all questions, order, and settings. That way it can:
- Answer “What’s on the form?”
- Add or update questions in the right place
- Avoid duplicates and keep structure consistent
So the AI form builder is always working with the latest version of your form. This is essential for iterative refinement and for form builder workflows where multiple edits happen in one session.
Other Antforms features (beyond AI)
- Unlimited forms and responses on the free tier — No per-response paywalls; scale contact form and survey volume without surprise costs.
- Conditional logic — Show or skip blocks based on answers; essential for quizzes, lead qualification, and contact form branching.
- Form analytics — Overview, over time, drop-off by block, device, referrer, geography.
- Share by link — No login required for respondents.
- File uploads — Collect files or images; download from the responses view.
So Antforms is both an AI form builder (conversational creation and edits) and a full form builder (logic, analytics, many question types) with no response caps on the core product. It fits the definition of best free form builder for teams that need form builder with AI plus unlimited responses and form builder software-grade features.
Best for
- Surveys and feedback — NPS, satisfaction, open-ended feedback.
- Contact and lead forms — Email, name, message, optional phone/company.
- Quizzes — Multiple choice, statements, scoring (structure created by AI, logic by you).
- Event registration — Collect name, email, preferences; optional file upload.
- Anyone who wants to build forms faster — Describe in plain language, then tweak in the builder.
Antforms as an AI form builder is designed for startups, developers, and product teams who want to ship forms quickly without sacrificing conditional logic, analytics, or unlimited responses.
Why choose an AI form builder in 2026?
Traditional online form builder workflows require you to add each field manually, configure options one by one, and then wire up logic and styling. An AI form builder compresses that: you describe the outcome (“feedback survey with NPS and comment”), and the AI form generator produces a first draft. You then refine in the visual editor—moving questions, changing labels, or adding conditional logic—so the result matches your brand and flow. The benefit is speed: contact form builders, feedback form creators, and survey designers can go from idea to published form in minutes instead of hours. For form builder software evaluation, look for both AI-assisted creation and full control (edit, reorder, branch); Antforms provides both so you’re not locked into AI-only output.
Getting started with Antforms
- Sign up at app.antforms.com and create a new form.
- Describe in natural language what you want—e.g. “Create a contact form with name, email, and message” or “Add an NPS question and a follow-up comment box.” The AI form builder will add the blocks.
- Refine in the visual editor—reorder questions, change labels, set required/optional, and add workflow and branching (e.g. show “Why?” only when NPS is low).
- Adjust appearance—primary color, thank-you message, redirect URL—via settings or by telling the AI.
- Publish to get a shareable link; responses appear in the dashboard with form analytics (completion, drop-off by block, device, referrer).
- Connect webhooks (optional) to send submissions to your CRM, Slack, or Google Sheets so the form builder fits into your stack.
Industry adoption of AI form generator and form builder with AI tools is growing: teams use them to build contact form pages, feedback form flows, and online form builder experiences in a fraction of the time of manual configuration. Antforms fits that trend while remaining a free form builder at its core—no paywall on forms or responses.
As a best free form builder with unlimited responses, Antforms lets you iterate without worrying about caps. Forms are served over HTTPS and responses are stored securely; you control where data goes via webhooks.
