Expert system solutions provide a logic-based form of workflow automation that allow for custom applications to be built using flowchart-type ("if-then") reasoning. Often, the front end interface of these applications provides a questionnaire that allows users to self-serve the information or knowledge they need to know. Common examples of expert system applications include the automation of multi-jurisdictional regulatory review or unifying a complex onboarding system involving multiple processes into a single dashboard. Neota Logic has long been the industry leader in this area. Bryter is a low-code version that has recently become a strong competitor, with smaller tools such as Joseph starting to gain traction.
