With PBX, building a b tests has become so easy that knowing what to test has become your real advantage. Because no matter the size of your company, your traffic is still a limited resource and you can't test everything. That's why we're so excited to partner with Conversion by Gain, the leading experimentation agency to introduce test ideation as part of PBX. So let's take a look at how it works. So to start, you'll just provide your page's URL to have it scanned. After a few minutes, your hypotheses will be ready for your review. You'll see a summary of the hypothesis as well as its corresponding test idea. Our AI agent has scored each test idea and flags the one that's most likely to drive measurable impact. You can read more about the insights backing each hypothesis. Test ideation is using learnings from over twenty zero experiments to find the ideas that are most likely to win. In fact, our test ideas are up to three times more likely to produce a positive result than the industry benchmark. Now down here, you'll see the recommended test idea, and it further breaks down into the variations that you can create to validate or invalidate this hypothesis. Choose the one that you'd like to move forward with, and you can just pick the high priority ideas and build them instantly with PBX. You don't even need to write a prompt. It's already done for you. All you need to do is hit submit. It's that easy to go from idea to launching a test in just a few clicks. Test ideation is the first set of AI agents that mimics a CRO expert by scanning your pages and recommending tests based on a rigorous framework and deep contextual insights, resulting in a b tests that are three times more likely to succeed. If you wanna be among the first to try it, join our wait list today.

ChickyTutor Redesign

UX optimisation

by

Phanos Anastasiou

My original landing page optimizes for low time to value (show me how it works) instead of traditional landing pages that focus on copyright (tell me how it works). I wanted to create a new landing page that does both! PBX built a full-screen, polished, redesigned page overlay with Hero + “Session Builder” panel (scenario + length), Feature cards for Writing + Visual learning, How-it-works + FAQ, and a Sticky CTA.

H&M Product Videos

Product Visualisation

by

Priya Rani

Having a video on product detail page attracts users and helps in conversion. I was trying to see the capability of PBX if it can create videos too, but PBX is not yet capable of creating videos. Though, It did a good job of adding the video thumbnail and placeholder.

Triumph Sizing on CTAs

Product Visualisation

by

Montserrat Eguia

Hypothesis: Making the chosen size visible at the moment of clicking will increase confidence, reduce misclicks or wrong-size additions, and therefore raise add‑to‑cart and purchase rate. By reducing uncertainty (“Did I pick the right size?”), the experience should feel more guided and trustworthy.

Nike Customizations Pop Up

Pop-In

by

Priya Rani

Nike is allowing user to design shoes on their own. When I landed on the PDP, I saw an option to design. But as a user, I had no idea what I was supposed to do next. Using PBX, I added a popup to show the steps on how it works. I also added a "how it works" link so users can click to know the step by step process on customization. I believe this will be a selling point for the custom design feature.

Reducing Bounce from Google Shopping Traffic on Maison Margiela

Product Visualisation
Filters

by

Amaury.O

I was inspired by the need to capture and retain high-intent traffic from Google Shopping and paid ads, where users are typically in a fast-paced comparison phase and highly likely to bounce back to search results. Knowing that every bounce represents both a lost opportunity and wasted ad spend, I designed a compact, horizontal recommendation bar to act as a strategic safety net.

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.

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.

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 later in Q1 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.
