Lily O'Brien's Product Card Alignment

AB Test

by

Sarah Lachapelle

Our hypothesis is that the alignment of the text being centered makes it hard for users to quickly scan / read, and quickly compare product info. Also the add to bag icon is very subtle on these PLPs we wanted to enhance the layout to see if we can increase conversions from these pages, particularly on mobile.

StubHub Dark Mode

Filters

by

Dylan Davis

I decided to redesign a website that I frequent, Stubhub. I redesigned the homepage to have a dark mode switch, that changes the background and font with a focus on accessibility. I always enjoy switching to dark mode to save my eyesight.

Triumph Sizing Dropdown

Filters

by

Montserrat Eguia

The goal of this A/B test is to prove that using two separate dropdowns for lingerie sizes—one for Unterbrustumfang (underbust measurement) and one for Cup-Grösse (cup size)—provides clearer size selection and improves customer experience. This should reduce confusion and uncertainty by letting customers pick band and cup sizes independently.

Sparkles and Spicy Margs at The Initial

Lucia van Den Brink

I was at Conversion Hotel last weekend and had too many spicy margs with heroes in our industry, which led me to this beautiful redesign of my consultancy's page. I'm sure it will be good for conversions.

Eterna Snow

Just listened to the radio and Shakin' Stevens song "Merry Christmas Everyone" was playing. "Snow is falling all around me ..." was a great inspo for the prompt in combination with our Festive / Christmas campaign. Gives the Festive landing page a nice and cozy Christmas touch.

Product Sizing for Triumph

Filters

by

Montserrat Eguia

By merging size and cup, customers will more easily see whether their size is available. Currently, band and cup sizes are split, which sometimes makes customers think a size is available, but once they click on the band size, they realize there is no availability.

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 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.
