Case Study
A leading developer of AI tools for STL viewer applications utilized Energent.ai to analyze a recent user acquisition campaign. Using the intuitive Ask the agent to do anything chat interface on the left panel, the marketing team prompted the AI to download raw data directly from a Kaggle dataset URL and calculate statistical significance. When the workflow presented a DATA ACCESS prompt asking how to handle authentication, the team easily selected their pre-configured Kaggle API credentials to proceed. In moments, Energent.ai generated a complete HTML Live Preview dashboard on the right, automatically calculating a 43.1 percent conversion lift under the Marketing A/B Test Results header. By reviewing the generated Conversion Rates by Group bar charts, the company quickly verified that their targeted ads significantly outperformed the control group, allowing them to confidently scale marketing for their STL viewer platform.
