AI Webform Generator: How to build Drupal Webforms from a single sentence

Creating a Webform in Drupal is not difficult. It can, however, involve a lot of repetitive work.

You add a field, choose its type, and configure it. Then you add another field and configure that one. You keep going until the form is complete.

Now imagine simply telling Drupal what form you need. For example:

"Create a customer feedback form with name, email, rating, and comments."

That's the idea behind the AI Webform Generator. The module lets you describe a Webform in plain English and uses AI to create it for you. It can also update an existing Webform based on your instructions.

Key Takeaways

• AI Webform Generator is a Drupal module that turns a plain-English description into a Webform. It can also update existing Webforms from your instructions.
• It talks to AI providers through Drupal's AI module. You can switch providers without changing the generator, and API keys stay managed by Drupal AI.
• Every AI response is validated before anything is saved. Unsupported field types, duplicate machine names, empty option lists, and invalid min/max values are rejected.
• Separate permissions and per-user flood control decide who can generate forms and how many AI requests they can make.
• The result is a standard Drupal Webform. Emails, handlers, validation, and submissions work like any other Webform.

What can the AI Webform Generator do?

AI Webform Generator provides a simple interface at /admin/structure/webform/ai-generator.

You describe what you want, and the module creates the Webform. For example:

"Create a registration form with name, email, phone number, date of birth, and a checkbox to accept the terms."

The module generates the matching Webform and saves it in Drupal. You can then open it in the normal Drupal Webform interface and make any additional changes you need.

Can it update an existing Webform?

Yes. You don't have to create a new form every time. Select an existing Webform and ask the AI to make a change, such as:

"Add a phone field and a resume upload field."

"Remove the Comments field and add CAPTCHA."

"Rename Rating to Satisfaction Score."

The module understands the existing fields and applies the requested changes.

Why use AI to build Drupal Webforms?

Creating a Webform manually isn't necessarily a difficult task. The problem is that it can be repetitive.

A simple form might only need a few fields. Larger forms can mean configuring dozens of fields and settings.

This is especially common for sites that regularly create:

• Feedback forms
• Registration forms
• Surveys
• Application forms
• Contact forms
• Event forms
• Intake forms

AI Webform Generator reduces the amount of repetitive setup. Instead of starting with a blank form, you start with a description.

What does it look like in practice?

Imagine you need a customer feedback form. Normally, you might manually create:

1. Name field
2. Email field
3. Rating field
4. Comments field

With AI Webform Generator, you can simply write:

"Create a customer feedback form with name, email, a rating from 1 to 5, and a comments field."

The process becomes:

Your sentence
↓
AI generates the fields
↓
Drupal validates them
↓
Webform is created
↓
You continue editing it normally

The final result is still a standard Drupal Webform. You can edit it, configure emails, add handlers, change validation, and manage submissions just like any other Webform.

Does AI replace Drupal Webform?

No, and this is important to understand. The module isn't trying to replace Drupal Webform. It simply helps you create the initial structure faster.

Once the form has been created, you keep working with it in Drupal's standard Webform interface. The workflow is:

Describe → Generate → Validate → Edit

The AI helps with the first part. Drupal remains in control of the final Webform.

How does AI Webform Generator connect to AI providers?

The module does not connect directly to OpenAI, Anthropic, or any other AI company. It uses Drupal's AI module instead.

This matters because Drupal AI already gives modules a common way to communicate with different AI providers. The setup looks something like this:

AI Webform Generator
↓
Drupal AI
↓
AI Provider
↓
OpenAI / Anthropic / etc.

The Webform Generator doesn't need to know which provider is being used. If your site uses OpenAI today and switches to another provider later, the Webform Generator needs no changes.

Where do your API keys stay?

Because it relies on Drupal AI, this module doesn't need to manage your AI provider's API keys. The credentials are configured through Drupal AI and its provider integrations.

AI Webform Generator simply asks Drupal AI to generate a response. It does not store or export the API key. That keeps responsibility for AI credentials in one place.

How does the module validate AI-generated Webforms?

This is probably the most important part of the module. AI can be very useful, but it can also make mistakes.

For example, an AI response could contain:

• A field type that Drupal does not support
• Two fields with the same machine name
• A dropdown without any options
• An invalid minimum and maximum value
• A missing field type
• An incomplete response

So the module does not immediately save whatever the AI returns. The response first goes through a validation process. The basic flow is:

User's prompt
↓
Drupal AI
↓
AI-generated form definition
↓
Validation
↓
Create or update Webform

If validation fails, the form is not saved.

Which field types is the AI allowed to use?

The module keeps a predefined list of field types the AI is allowed to use:

• Text field
• Text area
• Email
• Telephone
• URL
• Number
• Date
• Checkbox
• Radio buttons
• Select list
• Password
• File upload
• Range
• CAPTCHA

This list is maintained in one place inside the validation code. The same list is also given to the AI when the prompt is created.

The AI knows what it is allowed to generate, while Drupal independently checks that the response follows the same rules. In simple terms, the AI gets the rules, and Drupal checks the rules.

What does the validator check before a form is created?

The validator performs several checks before it allows the form to be created.

Required information. The response must contain the basic information needed to create a Webform, such as a title and elements. If important information is missing, the response is rejected.

Field names. Every Webform element needs a machine name. The module makes sure those names follow Drupal's expected format and that two fields don't accidentally use the same name.

Select and radio options. If the AI creates a select list, radio buttons, or checkboxes, there must actually be options. This, for example, would be invalid:

Rating:

[ Select an option ]

with no available options. The validator catches that before the form is saved.

Numeric values. The module also checks numeric validation rules. Take this example:

Minimum: 10

Maximum: 5

That is obviously incorrect. The validator rejects it instead of saving an invalid configuration.

What happens when you update an existing Webform?

Updating an existing form needs a little more care. The module does not simply give the AI everything inside the Webform and allow it to change anything. It provides the AI with the fields the generator manages.

Suppose a Webform contains Name, Email, and Comments. You ask:

"Add a phone number field."

The AI works with the fields managed by the generator and returns the updated definition. The existing Webform itself is preserved, and its Webform ID and URL do not change.

What about manually created Webform elements?

Some Webforms contain more complicated structures, such as:

• Containers
• Wizard pages
• Composite elements
• Custom structures created manually

The module intentionally leaves these unmanaged structures out of the AI's update context. This means the AI cannot accidentally rewrite something the generator does not own.

The basic idea: the generator manages what it created. Drupal continues to manage everything else.

Who can generate Webforms, and how do you control AI usage?

Which permissions does the module add?

Using AI does not bypass Drupal's normal permissions. The module provides a separate permission, Generate AI Webforms. Only users with this permission can generate or update Webforms using AI.

There is also Administer AI Webform Generator. This permission is intended for administrators who need to configure:

• AI provider
• Model
• Temperature
• Maximum output tokens
• Usage limits

The separation is useful. Not every person who can create a form should be able to change the site's AI configuration.

How does flood control limit AI requests?

AI requests can cost money, depending on the provider being used. Because of that, the module includes a flood-control mechanism.

Administrators can limit how many AI requests one user can make during a specific period. For example:

Maximum requests: 10

Time window: 1 hour

This helps prevent someone from accidentally (or intentionally) generating hundreds of AI requests. Administrators can also configure:

• AI provider
• AI model
• Temperature
• Maximum output tokens
• Flood limit
• Flood-control window

Why do the validation and permission layers matter?

Using AI to generate configuration is different from generating text. The output eventually becomes part of the Drupal site. So the module has to be careful about what it accepts and who is allowed to use it.

AI Webform Generator puts several safeguards around the AI:

• Supported field types are restricted.
• AI responses are validated.
• Invalid fields are rejected.
• Duplicate machine names are prevented.
• Existing Webform structures are protected.
• Drupal permissions are respected.
• AI usage can be limited per user.
• API credentials remain managed by Drupal AI.

Faster Webform creation is only half the goal. The other half is making AI-assisted Webform creation predictable and controlled.

How do you set up AI Webform Generator?

Setup takes five steps. Each step below lists what to do, where to go, and what to configure. Check the requirements first.

What do you need before you start?

Required

• Drupal Webform
• Drupal AI
• At least one chat-capable AI provider configured through Drupal AI

Optional

• CAPTCHA module, required only when CAPTCHA elements are generated

Step 1: Configure Drupal AI

• What to do: Configure a chat-capable AI provider through Drupal AI.
• Where to go: Configuration → AI → AI Settings (/admin/config/ai/settings)
• What to configure: The AI provider and its credentials.

Step 2: Enable AI Webform Generator

• What to do: Enable the three required modules.
• Where to go: Extend (/admin/modules)
• What to configure: Enable webform, ai, and ai_webform_generator. At least one chat-capable AI provider must already be configured through Drupal AI.

Step 3: Configure the generator

• What to do: Set up how the generator talks to AI and how much it can be used.
• Where to go: Configuration → AI → AI Webform Generator (/admin/config/ai/webform-generator)
• What to configure: The generation settings (AI provider, AI model, temperature, maximum output tokens) and the usage settings (flood limit and flood-control window).

Step 4: Give users permission

• What to do: Decide who can generate forms and who controls AI settings.
• Where to go: People → Permissions (/admin/people/permissions)
• What to configure: Give trusted users the Generate AI Webforms permission. Keep Administer AI Webform Generator limited to users who should control AI settings and usage.

Step 5: Create your first Webform

• What to do: Describe the form you want in plain English.
• Where to go: Structure → Webforms → AI Webform Generator (/admin/structure/webform/ai-generator)
• What to configure: Enter your prompt, for example: "Create an event registration form with name, email, phone number, event date, number of attendees, and dietary requirements." The module handles the rest.

Final thoughts

AI Webform Generator is built around a simple idea: describe the form you need, and let Drupal build the starting point for you.

Instead of adding repetitive fields one by one, a site builder describes the requirements in plain English. Drupal AI handles communication with the configured AI provider, the generator validates the response, and Drupal Webform creates the final form.

The result is still a normal Drupal Webform: editable, configurable, and fully managed through Drupal. For teams that create Webforms regularly, a repetitive setup task becomes much simpler.

Frequently Asked Questions

Does AI Webform Generator connect directly to OpenAI or Anthropic?

No. Every request goes through Drupal's AI module, which gives modules a common way to communicate with different AI providers. The generator doesn't need to know which provider your site uses. If you move from OpenAI to another provider later, AI Webform Generator itself needs no changes.

Where are my AI provider's API keys stored?

API keys are configured in Drupal AI and its provider integrations, not in AI Webform Generator. The module only asks Drupal AI to generate a response. It does not store or export the key, so responsibility for AI credentials stays in one place on your site.

What happens if the AI returns an invalid form?

The form is not saved. Every AI response passes through validation first. The validator rejects missing titles or elements, badly formatted or duplicate machine names, select lists or radios with no options, and impossible numeric rules like a minimum of 10 with a maximum of 5.

Which field types can AI Webform Generator create?

It can create 14 field types: text field, text area, email, telephone, URL, number, date, checkbox, radio buttons, select list, password, file upload, range, and CAPTCHA. The same list is given to the AI in its prompt and checked by Drupal during validation.

Will updating a Webform with AI change its ID or URL?

No. When you update an existing Webform, its Webform ID and URL stay the same. The AI only receives the fields the generator manages. Containers, wizard pages, composite elements, and other manually built structures are left out of the AI's update context, so they can't be rewritten by accident.

How can administrators keep AI costs under control?

Flood control caps how many AI requests one user can make in a set time window, for example 10 requests per hour. Administrators with the Administer AI Webform Generator permission can also set the AI provider, model, temperature, and maximum output tokens.

What modules do I need to install?

You need three modules enabled: webform, ai, and ai_webform_generator. You also need at least one chat-capable AI provider configured through Drupal AI. The CAPTCHA module is optional and only required when the AI generates CAPTCHA elements. Set up the provider first under Configuration → AI → AI Settings.

Can I still edit a Webform after the AI creates it?

Yes. The output is a standard Drupal Webform. You can open it in the normal Webform interface to edit fields, configure emails, add handlers, change validation, and manage submissions, just like any Webform you built by hand. The AI only builds the starting structure, and Drupal stays in control of the final form.
