PromptQL is a solution that enables Credit Unions to deliver explainable product recommendations, helping build trust with their members. The Fintech business was trying to solve this problem but faced challenges with previous approaches being vague or untrustworthy. PromptQL provides human-readable and accurate reasoning behind AI recommendations, creating trust in otherwise opaque models. This allows for rapid deployment of new recommendation systems without reworking existing data infrastructure, enabling faster experimentation and improved teller experiences. With PromptQL, the customer can now onboard new credit unions quickly, explore additional use cases such as targeted marketing and internal automation, and deliver high accuracy with near-zero setup. The solution detects logic flaws in real-time and provides self-debugging capabilities, making it a game-changer for both the Fintech business and Credit Unions.
