Tips and cases of use for a successful WordPress website with calculated forms.
A friend forwarded me a LinkedIn post last month. Someone had generated a 12-field booking form using an AI assistant inside a WordPress plugin and posted a video of the whole thing taking about forty seconds. I was skeptical, but also curious — I run a small studio and we ship a lot of forms for clients. Anything that cuts the boring part of that work is worth a look.
So I spent a week using the AI form generator inside Calculated Fields Form to build real forms for real clients. Not demos. Real intake forms for a yoga studio, a dental clinic, and an equipment rental business.
Here's what I learned.
Calculated Fields Form ships with two AI surfaces in the admin. The first is the form generator: you describe the form you want in plain language, the assistant produces a draft, and you drop it into the visual builder to tweak. The second is an assistant panel that helps you write formulas, set up conditional logic, and troubleshoot calculation errors without leaving the form editor.
Both connect to whichever provider you configure in the plugin settings. I tested it with MiniMax and OpenAI, since those were the two I already had API keys for. The plugin also supports Anthropic Claude, Google Gemini, DeepSeek, Kimi, MiniMax, and the WP 7.x Connectors module if you want to keep everything inside WordPress.
For this article I'm only talking about the form generator, not the assistant panel. That's a different post.
The yoga studio needed an intake form with about twenty fields across three pages: personal info, current health conditions, and class preferences. The math was simple — they offer a 15% discount for students and seniors — but laying out a three-page form by hand is tedious even with a drag-and-drop builder.
I typed something like:
"Three-page yoga studio intake form. Page 1: name, email, phone, date of birth. Page 2: checkboxes for health conditions (back pain, pregnancy, recent surgery, none), text area for additional notes. Page 3: class preferences dropdown (beginner, intermediate, advanced), preferred schedule checkboxes (morning, afternoon, evening), student or senior discount toggle. Add a calculated field that applies a 15% discount to the membership fee when the toggle is on."
The generator produced a working draft in under a minute. Every field was in the right page. The dropdowns and checkboxes were configured. The calculated field was there with a placeholder formula I had to refine, but the structure was correct.
What it saved me was the boring part: dragging fields, naming them, configuring options, organizing pages. That alone is about twenty minutes per form. Over a week of doing this for three clients, I saved roughly an hour.
For the equipment rental business, the AI even caught a field I hadn't asked for — a pickup date field with date validation — and added it on its own. That was a nice surprise.
The form generator is good at structure. It's not good at business logic.
For the dental clinic, the form needed a calculation that was anything but straightforward. The base price depended on the selected procedure, but there was a tiered discount based on insurance provider, plus an add-on for emergency appointments that applied a surcharge. I described the rules in detail and the generator gave me back a calculated field with a single line formula that ignored most of them.
I ended up writing the formula myself in about ten minutes. That's fine — I'm not paying for an AI to replace my judgment on pricing logic. But it's worth being honest about what the generator is good at: structure, not rules.
Same story with the conditional logic. The generator will create basic show/hide rules on request, but anything that branches more than one or two levels deep tends to come out wrong. I'd recommend using the generator for the form skeleton and writing the conditional logic manually.
The other thing I noticed: the generator defaults to English field labels unless you tell it otherwise. For one client who needed bilingual labels (English and Spanish), I had to translate the labels myself after the draft was generated. Not a deal-breaker, just something to plan for.
The AI form generator is a real time-saver for the part of form-building that everyone finds tedious. If you're building forms regularly, it's worth the few minutes it takes to configure an API key and try it.
It's not a replacement for thinking through your form's logic. Use it for the skeleton, then refine.
If you're wondering whether it works with the free version: yes, the AI features are available in the free Calculated Fields Form plugin. You just need your own API key for whichever provider you want to use. That's a fair deal — you're paying the provider directly, not the plugin author.
I'll write up the assistant panel — the one that helps you write formulas — in a separate post. After using both for a week, I'd say the assistant panel is actually more useful than the generator for technical work. Stay tuned.
