VisiRule is a Low-Code No-Code AI tool that allows subject matter experts to create decision tree flowcharts for intelligent advice and troubleshooting. It can incorporate rules discovered from data using AI machine learning. VisiRule helps to handle common but non-trivial enquiries and computations in a cost-effective way, freeing staff to focus on more difficult tasks. It enables users to access expert knowledge and obtain personalized advice online via Intelligent ChatBots or automated processes. VisiRule combines visual diagramming and executable code generation to support automated decisioning, eliminating the need to encode know-how into incomprehensible "computer gobbledygook". Authors can keep their online advice current using a visual model as regulations, best practice, and people change.
