Cake: The first AI agent capable of continuously improving your website.

Hey Product Hunt 👋 I’m Fabrice, co-founder of Keak. Two years ago I was running performance marketing campaigns and manually writing A/B test variants for landing pages. It was slow, expensive, and honestly the AI ​​started killing me. So we created Keak. We fine-tuned a model based on thousands of successful CRO experiments. It now produces variations that outperform what most human copywriters come up with, and it gets smarter with each test. Here’s how it works: 1. Install the Chrome extension and click on any element on your site. 2. Cake instantly generates AI variants, no script needed, completely free 3. Start A/B tests with one click 4. When statistical significance is reached, Cake learns from the results and generates the next round of variants 5. Repeat, forever, automatically 6. Loop compounds. Each test optimizes the model for your specific site and audience. We also shipped two more products today: 1. CakeCode: for teams that want to run experiments directly from their codebase 2. CakeAgents: An open source standard for exposing structured tools for AI agents, including A/B testing. Works on Shopify, Webflow, Framer, WordPress, Wix, Squarespace, and anything with a URL. Most languages ​​are supported. Picture-to-picture and picture-to-video variations are supported. Generating variations is free. Break down your conversion rates. We read every comment, brutal feedback is especially welcome.
