CoolTool

CoolTool is an innovative market research platform that helps you look beyond what consumers say to understand how they actually feel. By integrating neuromarketing tools like eye tracking, facial coding, and brain activity measurement directly into your browser, you can capture subconscious reactions to your advertisements, packaging, and website designs in real-time.

You can build sophisticated surveys and combine them with biometric data to get a complete picture of the customer journey. This approach eliminates the bias of self-reporting, allowing you to see exactly where people look and how their emotions shift during an experience. Whether you are testing a new brand concept or optimizing a digital interface, the platform provides the automated heatmaps and emotional charts you need to make data-driven decisions.
