Form AI (Divi 5)
Form AI uses OpenAI to generate form fields and behavior from a prompt. Before building your first AI-powered form in Divi 5, be aware of limits and prerequisites.
Before you start
- PHP 8.1 or higher on the server.
- An OpenAI account with billing enabled.
- A valid OpenAI API key added in Form Builder settings.
- Access to the Divi 5 Visual Builder with a Form module already on the page.
Use OpenAI API setup if you still need to create or connect your key.
Limitations
- You can use one AI field per form.
- You can use one form containing an AI field per page.
- GPT-4-class models are generally more expensive than GPT-3.5-class models.
- If AI depends on a select field value, set a clear placeholder on that select field.
Recommended setup order
- Complete OpenAI API setup.
- Add a Form module in the Divi 5 Visual Builder.
- Enable and configure your AI field settings.
- Save and test with realistic prompts and inputs.
Verify it works
After setup, confirm:
- The AI field returns output instead of staying empty.
- The response appears within acceptable time for your model.
- The output matches your prompt intent and field constraints.
- Form submission still works when AI is enabled.
Common issues
- No AI response: confirm API key, billing, and selected model access.
- Response too slow: test with a lighter model and shorter prompts.
- Unexpected output format: simplify prompt wording and add clearer instructions.
What's Next
- OpenAI API setup - connect and test your OpenAI credentials.
- Form settings - configure redirects and notifications after AI output.
- Spam protection - reduce abusive submissions on AI-enabled forms.
