Trust Signals for Trusted Housesitters

Reviews

by

Adam Cheal

Sitters on Reddit say they struggle to see which hosts are experienced or safe without clicking into every listing. A compact trust line like “⭐ 12 reviews · 3 repeat sitters” on each card lets them gauge reliability at a glance, reduces anxiety and wasted clicks, and helps new sitters choose better first applications.

CNN Accessibility Suite

Filters

by

Ayomidotun Ayoku

We know CNN is visually chaotic, focusing on a single story is often impossible. I recently came across two websites with impressive accessibility layers and was inspired to bring that same experience to a major news platform. I wanted to prove we could bring 'calm' to the busiest site on the web.

Discount Timer for Triumph

Animation

by

Montserrat Eguia

We want to add a timer on discounts to create a sense of urgency. By using a discount timer, the expected benefits will be to increased conversion rates, as customers are nudged to act faster. It can also reduce cart abandonment and boost average order values, since customers may be more motivated to add items while the offer is still valid.

Book Finder Quiz for Waterstones

Product Visualisation

by

Georgiana Hunter-Cozens

I often get frustrated of 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. 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!

Booking.com Destination Carousel

Header

by

Andrei Stoleriu

Casual browsers who, at one point, were looking for a specific travel destination might be interested in an alternative destination in the same area, but need to scroll for a while below the fold to access similar destinations. I brought the alternative destinations further up the page and made the element more lightweight so it's easier for users to navigate.

Triumph Site Personalization

Pop-In

by

Montserrat Eguia

This idea is for the upcoming Black Friday campaign. I want to offer personalized discounts to customers and keep all communication direct. That’s why I’m asking for each customer's name, to make the experience more personal. The customer will feel the discounts are made specifically for them, we could use data and show this once a customer has visited more than 1 page or clicked 3 products.

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.
