VisiRule is an easy-to-use Low-Code No-Code AI tool for subject matter experts, like lawyers, tax advisors, engineers, to rapidly define and deliver intelligent advice and troubleshooting guides using decision tree flowcharts. VisiRule can also incorporate rules discovered from data using AI machine learning via VisiRule FastChart. ​ VisiRule builds systems to handle those common but non-trivial enquiries and computations that people have to spend time on, and customers want solving, in a cost-effective way. This frees staff to focus on the more difficult tasks, and empowers clients with instant access to high-quality advice anywhere, anytime. Use cases include problem triage with recommended prescriptive actions plus document generation. You can enable users to access expert knowledge and obtain personalised advice online via Intelligent ChatBots or automated processes. ​ VisiRule combines visual diagramming, executable code generation to support automated decisioning. This eliminates the need to encode know-how into some incomprehensible “computer gobbledygook”. Authors can keep current their online advice using a visual model as regulations, best practice and the people change. VisiRule allows authors to capture, evaluate, refine and deploy their expertise.
