Low-Code No-Code Expert Systems

VisiRule is a graphical tool for non-programmers to quickly and easily develop and deliver rule-based expert systems simply by drawing their decision logic. VisiRule offers a Low-Code No-Code way to build expert systems. Legal services, financial modelling and medical diagnosis are just some of the application areas where VisiRule is particularly well suited.


VisiRule allows you to imagine, explore and deliver a wide range of new, innovative, intelligent software products and automated services ranging from interactive chatbots to fault finding diagnostic systems.


Business Rules Engines and Application Logic

Business Rules Engine solutions are created using familiar graphical icons and links. Business Rules expose the valuable business knowledge that is locked up inside most organizations. VisiRule helps unlock that latent potential. VisiRule converts this into code that the underlying logic-based inference engine can execute with a high degree of compliancy and accuracy.

Expert Knowledge-Intensive Applications

VisiRule is ideal for building regulatory compliance systems, financial and legal decision-making systems, and both diagnostic and validation systems.

Intelligent ChatBots

VisiRule decision tree flowcharts can be used to provide the conversational flows which make up the backbone of intelligent logical chatbots.

Recommendation Systems

VisiRule can be used to help recommend suitable products and services using AI rules and rule-based inferencing.


Decision Tree Flow Charts

VisiRule structures its knowledge using decision tree flowcharts which combine aspects of decision tree software with process flow to make for decision tree flow charts. These are used to generate the expert system rules which, when executed, produce the desired behaviour.


Shareable Know-How

VisiRule charts can be shared and discussed with colleagues as diagrams with no need to buy or install any additional software. The knowledge underpinning the business decisions is made visible in a clear and coherent manner.


VisiRule Author provides a dedicated diagramming tool for experts to draw and test charts


VisiRule Publisher compiles the charts to automatically create questionnaire pages and associated rules


VisiRule Server executes each question page + the associated rules to compute the next page


VisiRule generates a final conclusion + reports, documents and transcripts using the answers given

Intelligent Authoring Tool

VisiRule helps in the knowledge capture and automation process by intelligently monitoring what can and can not done based on the its understanding of the emerging program. VisiRule will try and stop you using incorrect expressions or using the wrong object. This reduces the scope for constructing invalid or meaningless links, improves productivity and helps you spot errors early within the design process. A principal aim is to ensure that VisiRule can be used by business professionals as opposed to programmers. VisiRule has been specifically designed with lawyers, paralegals, auditors, compliance and healthcare professionals in mind.

Deliver Interactive Solutions

VisiRule knows which questions to ask and when. Question sequences are automatically constructed from the associated decision logic. Having evaluated the answer, VisiRule proceeds down the appropriate branch. This provides for the deployment of highly interactive and dynamic systems and can support the delivery of, for instance, troubleshooting flowcharts on mobile devices.


Deliver Data Driven System

VisiRule can extract answers from existing data sources. Where this happens, the question need not be asked, but the associated logic applied just as if the question had been asked interactively. This means you can develop your logic interactively, and, when you are ready, switch it over to run in a data-driven mode.


Benefit from Productivity Improvements

VisiRule transforms the experience of building decision support and business rules systems by reducing the production time while increasing the final consistency and quality of the delivered systems.

Expert Systems Software Technology


Multi-Layered Architecture

VisiRule is flagship of a Low-Code No-Code No-Cliff AI platform comprising:

  • VisiRule - No-Code visual authoring

  • Flex - Low-Code expert system software tool 

  • Prolog - a powerful No-Cliff AI programming language.


Flex Expert Systems Software

VisiRule generates code in terms of Flex, LPA's rules-based expert system shell tool using an English-like Knowledge Specification Language (KSL).


LPA Prolog

Prolog is a well proven AI programming language with pattern matching and logical inference. Prolog provides a robust foundation for the LPA stack.
