LeisureLabs developed a trainable AI chat tool using the OpenAI GPT3 framework (later upgraded to GPT4). In addition to web and mobile chat tools which allowed users to have their own conversations with BOB, the tool also featured a multi-tenant backend component allowing operators to “train” the AI by uploading resources, prompts and data (such as FAQs, training tips, information on specific exercises or products, and class timetables) which would allow the AI to develop unique knowledge relating to the client’s business and operating model. A proof of concept application was developed using the Open AI platform alongside a series of native and low code tools, including Flutter, FlutterFlow, Django and HTML.
