Driving upsell with goal proximity gamification for Adidas

UX optimisation
Gamification

by

Baveux Alexandre

This initiative leverages gamification by applying the Goal Proximity effect through an upsell mechanic designed to help users reach the next tier of the loyalty program. By clearly displaying the simulated progress toward the next loyalty level directly within the cart, the experience aimed to motivate completion, increase perceived value, and encourage users to add more items to reach the next milestone.

Reducing scroll to improve checkout progression for Puy du Fou

UX optimisation

by

Mathieu Azzopardi

This change aimed to reduce exits by minimizing scrolling on the order summary page. Key information was grouped into a single visible block, while cart details were moved into an optional accordion. By improving clarity and focus at this step, the experience encouraged smoother progression to the next stage of the checkout flow.

Find Alternatives on Nike

UX optimisation

by

Priya Rani

I noticed on the product detail page that if a variant was not available, the PDP neither showed an option to notify nor any other direction for users on what they could do next. I wanted to add a link for users to find an alternative/similar product. The idea was to direct the user to the recommended section and see some other similar products.

Lily O'Brien's Chocolate Discount Popup

Pop-In

by

Sarah Lachapelle

We want to increase our newsletter subscriptions, but not get in the way of the user experience too much while browsing. So we opted to create a pop-up on the most popular product list page right now and display it only after a 30% scroll, so that we know they are already engaged within the site. The pop-up offers an opt-in discount of 10% to help encourage users to sign up while engaged.

Compare mode for outdoor clothing in the The North Face shop

Product Visualisation

by

Samuel Sailer

Everyone knows product comparison by now. However, it is quite underutilized in fashion, especially in branches where products also have a functional purpose—like outdoor products, for example. As a user, I want a quick and easy way to compare jackets with regard to attributes such as waterproofing, insulation, wind resistance, etc.

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.
