Triumph Discount Roll-Up Display

Animation

by

Montserrat Eguia

The test aims to evaluate the effectiveness of a dynamic price display feature where the discount or price is animated to incrementally roll from 0 up to the actual amount. The core idea is to create a more engaging visual experience that captures user attention and emphasizes the value being offered. The incremental reveal can create a psychological effect, where users perceive the discount as large.

Bharat Security Real-Time Advice

Header

by

Mr. Kumar

I made this because most people only learn about scams after they get hurt. I wanted something on my website that warns and guides visitors in real time, while they’re actually browsing. Instead of building another demo in a sandbox, I wanted to see if AI could create something real, fast, and useful—something that actually helps people stay safe the moment they land on the site.

Lack of incentive to connect or register for the course for all users : Integrate a small bouncing pink dot designed to draw the user’s attention without being intrusive. A pop-up highlighting the key benefits of logging in or registering This subtle visual cue creates a gentle nudge that encourages users to take action.

Hamster Party at the New York Times

This solves the boring news problem. News is so boring and hamsters make it significantly better. New York is full of hamsters so I don't understand why they aren't on the site already, but this will definitely increase conversions.

Google stars reviews for Center Parcs resorts

Reviews

Arnaud Nigou

Customer feedback including reviews, comments, NPS surveys, support tickets, and chat interactions—is a crucial asset for CRO. It’s often overlooked, yet it reveals insights that Google Analytics or heatmaps alone cannot provide: the underlying “why” behind user behavior.

Choose Your Default View: Item vs. Outfit

Product Visualisation

by

EK

I used PBX to create a filter that lets shoppers choose how they want to browse handbags. On Net-a-Porter, you normally only see the item on its own, and the outfit view appears only on hover. I asked PBX to add a filter so shoppers can pick their preferred view, outfit or item right from the start.

FAQ

Does prompt-based experimentation decide what to test for you?

You can ask PBX to generate optimization ideas for you, then choose and implement the ones you prefer or request new suggestions. The more specific you are about your goals, the better the ideas PBX will generate.

How does the Starter plan compare to the Enterprise plan?

Our Starter plan includes a free trial with limited credits and Monthly Tracked Users. Upgrading to the full Starter plan gives you additional prompt credits and lets you run tests on more traffic. The Enterprise plan scales with your traffic needs and provides advanced capabilities, integrations, and enterprise-grade support. All plans include Kameleoon’s top performance, real-time data, and robust security features.

Is PBX vibe experimentation?

Just like vibe coding lets you create web prototypes instantly by chatting with AI, PBX lets you create new and optimized web product on your existing websites.  You get to test what you've created on real users on your actual website. The act of building variants and testing them by chatting with AI is called vibe experimentation.

Do you have a month-to-month plan?

Yes. Our Starter plan allows you to go month-to-month. No term required.

What happens to my tests after the free trial?

Your tests and data are NOT saved. You can upgrade anytime to keep running experiments without interruption.

How does the Free plan compare to the Starter and Enterprise plan?

The Free plan gives you access to PBX with limited credits. Our Starter plan gives you more prompt credits and allows you to test on more traffic. The Enterprise plan supports your traffic needs, unlocks unlimited credits, and offers advanced capabilities, integrations, and enterprise-grade support. Every plan comes with Kameleoon’s top speeds, real-time data and security features.

What is a “credit” and when does it get consumed?

Every time your prompt, one credit is consumed. Your free trial includes enough credits to explore all key features. If you have a promo code for more credits, you can enter it under the Organization page on your account. On average, our users builds an experiment by using 3 credits. contact@kameleoon.com for any questions!

What is Prompt-Based Experimentation (PBX) and how does it work?

Prompt-Based Experimentation (PBX) is Kameleoon’s approach to vibe experimentation; a new way to ideate, configure, and launch experiments. With PBX, you simply describe the web changes you want to test in natural language. AI then generates a variation and launches the experiment, without code or WYSIWYG editors.

Can prompt-based experiments target users based on external, third-party data?

Yes! Kameleoon's integrations allow you to personalize and target prompt-based experiments using data from your customer data platform or preferred data warehouse. For example, you can connect Kameleoon to your CDP to create segments based on customer subscription level.

Is prompt-based experimentation finished or complete?

Not yet. Because it relies on rapidly improving GenAI models, prompt-based testing will continue to evolve and expand in capability every day. It’s a new way to interact with an experimentation platform.

Is prompt-based experimentation statistically rigorous?

Yes, but only when used with proper guardrails. You still need valid KPIs, correct traffic splits, targeting, and robust statistical methods to draw meaningful conclusions.

Can prompt-based experimentation eliminate the need for developers?

It heavily reduces the need for developer involvement in each test, but developers should remain essential collaborators for quality, scale, and integration across teams.

Is prompt-based experimentation a replacement for Figma or CMS tools?

No. PBX helps you create test-ready experiment versions by chatting with AI, but it’s not a replacement for your design or CMS tools. You can still upload a mockup to improve output quality, and a Figma integration is planned for late Q4 2026.

Can prompt-based experimentation replace all other forms of experimentation?

No. It focuses on frontend digital experiences that optimize UI/UX and messaging. It compliments—but does not replace—feature flagging, server-side testing, or mobile app experimentation.

Is prompt-based testing the same as “testing prompts?"

No. Prompt-based testing turns a prompt into a testable digital experience. “Testing prompts” means refining the prompts themselves, which is usually done with backend or server-side experimentation.

Is prompt-based experimentation just an upgrade to the graphic editor?

No. Prompt-based experimentation leapfrogs visual editors entirely. It uses natural language to build, configure, and analyze experiments, making frontend testing more powerful and accessible than ever.
