Heatbot is designed to simplify the process of optimizing website user interfaces by utilizing heatmap data. Users start by uploading a screenshot of their website and the corresponding heatmap generated from user interaction data. They then set specific improvement goals, which guide the AI in analyzing the heatmap and generating enhanced HTML, CSS, and JavaScript code. This approach not only ensures data-driven decisions but also provides comprehensive improvement reports, making it easier to track and implement changes.
