The rules

Six kinds of rules. One prompt builds them.

Conditional logic isn't one feature. It's a set of decisions a form makes on the fly. Here are the six you'll build most often, with the exact rule on the right.

Type What it does Example rule
Show or hide a field Reveal a field only when an earlier answer matches. If "Are you employed?" = Yes, show "Employer name"
Skip a page Jump past sections that don't apply. If "Account type" = Personal, skip the "Company billing" page
Make a field required Toggle required-on-the-fly so the form stays short for everyone else. If "Need invoice?" = Yes, require "VAT number"
Filter the choices Narrow a dropdown based on a previous answer. If "Country" = USA, show US states; if "Canada", show provinces
Calculate a value Compute totals, scores, or pricing as the user fills. "Total" = "Quantity" × "Unit price" + tax
Route email and redirect Send the response to the right inbox and the right thank-you page. If "Department" = Sales, email sales@yourco and redirect to the booking link

Why teams use the AI to write the rules

star icon

Fast and Easy Setup

Create conditional logic forms using simple prompts. No need to manually set complex rules.

Edit the AI's logic before it ships

AI gets fast wrong sometimes. Every rule the AI writes lands in the standard rule editor first. Read it, change a condition, change the action, save. Nothing publishes until you say so.

Add rules to a form you already built

Paste any existing form into Formester (or import from Google Forms, Typeform, Microsoft Forms). The AI reads the fields and lets you describe rules against them, no rebuild.

STEP 3

Generate Conditional Rules with AI

Use a simple prompt to let AI generate your conditional rules. Just tell it how you want your conditional fields to behave.

Example: If the T-shirt type equals "Men" or if it’s empty, then Hide the fields "women size" and "kid’s size".

The honest comparison

AI rule-writer vs. clickable rule-builder. Where each one wins.

Most form builders ship a clickable rule editor. It works. It also rewards a specific shape of patience. Here's the honest comparison.

Manual rule-builder Formester AI rule-writer
Time to write a 6-rule form 15-25 minutes the first time Under a minute
Renaming a field with rules attached Hunt every rule, fix each one Re-prompt; the AI rewrites against the new name
Adding a rule to a form built last quarter Re-learn the editor Read the rule out loud, paste, done
Rule preview before publish Yes Yes
Edit a rule the AI wrote Yes, in the same editor Yes, in the same editor
Multi-condition AND / OR Yes, after a few clicks Yes, written as you'd say it
Forms with one rule Manual is fine AI is faster but not by much
Forms with twenty rules Painful Where AI earns the buy
Auditability of complex logic trees Visual flow chart in some tools Plain-English source of truth
The short version. A clickable rule editor is fine when you're writing one rule on one form once. The minute the form gets longer, the team gets bigger, or the field names start changing, the AI rule-writer pays itself back on every change.
Privacy and data

Your form data is yours. We don't train on it.

The prompt you type to describe your conditional logic, the form responses you collect, and the rules the AI generates from them are all Customer Data. Per Section 4.4 of our Data Processing Addendum, Formester does not use Customer Data to train AI models, run advertising, run analytics, or feed marketing. The Google Gemini integration that powers the rule generation inherits the same boundary.

Your account is encrypted at rest, your form responses move over TLS, and payment data carries an additional AES-256 layer through Stripe. We are GDPR, UK GDPR, and CCPA compliant. We are not SOC 2, ISO 27001, or HIPAA certified yet, and we say so on the security page rather than implying otherwise.

I really enjoy Formester. It’s clean and straight-forward and it does well, what it is supposed to do.

Formester is simple enough for non-developers and sophisticated enough for developers. I'd say being able to choose between simplicity and complexity is one of this product's strengths. In addition, the founder is available to answer questions and doubts, which does not happen every day.

Very intuitive and the surveys look genuinely professional out of the box. Most importantly, I requested a custom rating scale and they shipped it within hours. Stellar support that is hands-down better than the Jotform.

I'm migrating my forms from Paperform, where I've been a user for over 4 years. Loving the software so far! I've already replaced Paperform form embeds & popups on my sites & my husband's websites with Formester forms

Tried like 4 quiz tools for our lead gen funnel before this and honestly this is the only one I didn't end up hating. AI did most of the work and the customization actually works.
