The document discusses a modular and reusable approach to artificial intelligence. It introduces LogoGrab, a mobile app that allows users to scan logos using augmented reality. The company developed their own AI technology using a modular approach inspired by functional programming. This allows for composition of AI methods, lazy evaluation, caching, and encapsulation, which provides advantages like performance and flexibility. Their new architecture employs reusable "bricks" or modules of AI code combined through composition.
