Case Study: Whataburger achieves better customer review insights with Dataiku

Whataburger Using LLMs to Hear What Customers Are Saying

Whataburger, the U.S.-based regional fast food chain with more than 1,000 restaurants, needed a better way to analyze thousands of online and internal customer reviews for its dashboard. Its older bag-of-words sentiment approach was too rigid and required constant manual maintenance, so the company turned to Dataiku and its LLM capabilities to improve review categorization and sentiment analysis.

Using Dataiku’s Prompt Studios, Whataburger tested multiple LLMs and selected GPT for the best out-of-the-box performance and prompt handling. The new no-code, visual workflow lets the team quickly adjust categories, generate the dashboard dataset, and share insights with executives; with more than 15 million total reviews and over 10,000 new reviews per week, the solution helps Whataburger scale analysis and spend more time improving the customer experience.
