Announcing the winners of the world's first Promptathon

The world's first Promptathon is over and the results are in!
We challenged our community to optimize any digital experience by using Kameleoon’s prompt-based experimentation (PBX). From creating product quizzes to redesigning entire homepages, participants pushed the creative boundaries of PBX. However, a handful stood out to us as some of the most creative and high impact optimizations.
Here are our 2025-26 Promptathon Winners:
PBX Champion Award

Georgiana Hunter-Cozens is a Senior Strategy Consultant from the UK, and we were incredibly impressed with her Promptathon submission: an interactive quiz for the Waterstones website that offered helpful book recommendations for readers after only three questions.
"I often get frustrated by endless best seller lists and find Waterstones isn't great at helping me browse or discover new books; you pretty much have to know what you're looking for," she noted. "I was inspired to add a 'recommendations' carousel. I wanted to make it more personalized and give some agency to the recommendations, hence the book finder wizard!"
Her initial prompt was straightforward:
"Create a book finding wizard on this page, replacing the existing hero. It should be eye catching and encouraging visitors to engage to find their next read. The quiz should be quick and fun, with a focus on discovering hidden gems. The results should show 1-3 books and link to the relevant product page"
The initial output wasn't perfect, but was most of the way there; Hunter-Cozens's subsequent reviewing, refining, and debugging demonstrated her expertise in strategic optimizations and quickly brought the quiz up to a fully-functioning, visually impressive experience that feels like it's always belonged on Waterstones.
We loved this creative use of PBX and were impressed with how well it worked. Congratulations, Georgina Hunter-Cozens!

Alexandre Baveux is a Senior Consultant CRO/UXR from France who successfully gamified the Adidas checkout page, building a basic loyalty program from a single prompt to invigorate the purchasing experience.
“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,” he explains. “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.”
Baveaux put in some effort to iterate, engaging with PBX over a few hours (and sixteen prompts!) to refine and expand his experience. The result is a functioning loyalty program that correctly adds points based on cart value to encourage buyers to reach the next tier.
We loved the technical prowess demonstrated here and the effort evident in making it work. Congratulations, Alexandre Baveux!
PBX Elite Award

Priya Rani is a Product & Growth Consultant from India whose Promptathon submission was based around improving an existing experience. "Nike is allowing the user to design shoes on their own," she explained. "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."

Ayomidotun Ayoku is a Quality Assurance Engineer from Nigeria, and tackled a crucial issue for any website: accessibility. She used PBX to create an accessibility suite for the CNN website to break through visual clutters that make navigation difficult for some users.
Why not take the shot? Accessibility is non-negotiable, so I decided to test Kameleoon's AI builder by injecting a "Accessibility Suite" onto CNN. It includes a Focus Tunnel (for ADHD), Calm Mode (for sensory safety), and a Smart Reader. I am submitting this as an entry for the Promptathon. Check it out below.
From a widely-recognized symbol in the corner of the page, Ayoku's experiment adds "focus tunnel," "calm mode," and "smart reader" modes to improve readability and accessibility on the well-known news platform.
PBX Honors Award

Samuel Sailer is an E-Commerce Project Manager from Germany who used PBX to build a quick filter for Target’s product pages. With a single prompt (plus one follow-up for clarity), Sailer added filter presets for budget-friendly items, gaming products, office supplies, and adventurous items.
The filters already exist on the page, but clicking the new floating window applied several at once, cutting down on frictions that may slow down purchase. It’s a great use of PBX and an experiment we would love to see results for!
Honorary Mention

Pierre Marquis is a Web Analyst from France who made a simple but impactful change to the Promovacances site, making Tripadvisor reviews more visible to increase their readability.
"User reviews play a key role in the decision-making process and, when positive, significantly strengthen product credibility. Previously placed at the bottom of the page, they required extensive scrolling, limiting their visibility and impact. By moving user reviews to the top of the page, the objective was to surface social proof earlier in the journey and increase add-to-cart intent through the 'Book' buttons located further down the page."
Thank you to everyone who participated in the world's first Promptathon, and congratulations to our five winners. We'll see you soon for the next one!
“We needed a way to assess visitor interest more accurately. With manual scoring, lead quality was too low. We chose Kameleoon for its AI, which precisely targets visitors based on their interest in our cars.”

“This campaign shows the multiple benefits of artificial intelligence for personalization. Toyota’s teams have been completely convinced by the performance of Kameleoon’s AI personalization solution and are expanding this approach across the customer journey.”
