      Chatbot Solution Review from Daria Hlavcheva

      KeenEthics onboarded Lionwood Software to develop an AI-powered chatbot that could analyze photos of vehicle damage and provide an estimated repair cost for insurance company. The project focused on applying AI to a traditionally manual part of the insurance claims process. The solution needed to interpret car damage from uploaded images, identify relevant damage, and translate the analysis into a cost estimate that could support faster and more consistent claims assessment. Lionwood Software took ownership of the AI development and worked closely with the KeenEthics team to align the solution with the product requirements and insurance use case. Their team demonstrated a strong understanding of both the technical challenges of image-based damage assessment and the business logic behind insurance claims. They were proactive in discussing requirements, clarifying edge cases, and addressing dependencies throughout the development process. The resulting solution helped automate an important part of the vehicle damage assessment workflow, reducing the need for purely manual evaluation and creating a foundation for faster claims processing. Lionwood Software proved to be a reliable technology partner with the expertise to work on AI-driven products where technical implementation needs to be closely aligned with real-world business requirements.
