Rapid Prototyping Expert Systems

Powerful No-code Automation Software

VisiRule is a Low-Code No-Code tool which enables non-programmers to rapidly build smart applications using their own knowledge. VisiRule combines the best of expert systems software, rapid prototyping, decision trees, flowcharts and high quality document generation.


With VisiRule, you can rapidly develop intelligent advice and troubleshooting guides, and then deliver them in various ways ranging from multi-page web apps, AI ChatBots to automated Business Rules components.

Use visual rules authoring to handle those common but non-trivial queries that customers need solving in a cost-effective way anywhere, anytime. Keep current your online advice as regulations, best practice and people change. 


VisiRule generates executable code directly from the diagram. This eliminates the need to encode expert know-how into some “computer gobbledygook”.

Rapid Prototyping Software

Easy-to-use Rapid Prototyping Software

You can quickly create and immediately test your business logic with minimal training. This enables rapid prototyping of solutions.

Incremental Iterative Prototyping

VisiRule supports the incremental enhancement of software prototyping via incremental improvement and refinement.


VisiRule understands the context and purpose of its various nodes and links and guides you in the creation of decision models.


You can start by using interactive questions to obtain answers, and later switch to accessing external databases, CSV, Scada, IoT etc.

Document Creation

VisiRule includes a powerful document generation engine to automate document output in various formats such as text, PDF, XML, HTML and RTF. 

By associating suitably tagged document templates, i.e. boilerplates, you can produce high-quality documents based on the answers gathered in the session. Not limited to inserting simple values, you can combine complex logic with conditional text selection and insertion.​

Low Code Development Platform

Programming via Flow Charts

VisiRule’s 'programming via flow charting' permits the rapid prototyping and capture of knowledge. Like Visio and MindMap, you draw a model, but one you can execute instantly. Read an article about No Code and Lawyers here.

Low-Code No-Code Development

VisiRule supports Low-code programming via algorithms, code and scripts. Ths makes VisiRule a powerful Low-Code No-Code (or NoCode LowCode) tool. The code generator enables models to be immediately executed and tested.

Visualizing Knowledge

Knowledge is much easier to understand, study, assess, validate, maintain and share when presented visually as opposed to as blocks of text.


Easy to Deploy

JavaScript Delivery

Charts can also be delivered client-side using XML and a dedicated JavaScript engine to ask the questions and collate the answers. Users can revisit and re-answer questions in a highly responsive way; JS demo here:

Custom HTML Presentation

Questions can be presented in house-style simply by editing the CSS style sheets associated with the various assets, brands and icons. 

Put your brand in their pocket! 

Connected & Embedded Delivery

The same chart can be delivered using interactive web forms or via embedded Business Rules deployment using a REST API or as a chatbot.

Scalable & Affordable

VisiRule combines lean AI technology with modern cloud-based delivery to provide a scalable and cost-effective solution.

Easy to Share

Knowledge is Precious

VisiRule can help your company capture and retain valuable knowledge which can be shared and discussed as pictures or XML with colleagues.

Diagrams provides a clear way of representing decision logic - one that non-technical business users can immediately access and understand.​ 

Expertise can be shared across a wide group to help gather a consensus. After all, a picture is worth 1,000 words. The knowledge in a chart can be exported as a picture to help document the process.

Easy to Explain

Justify your Reasoning

Explainable AI means a solution can explain itself. Each visitor's execution path can be explained in terms of HOW, WHAT and WHY. Contrast this to neural nets which are black boxes and can NOT explain their reasoning.

Export All Answers

User sessions, including all answers, calculations and conclusions, are logged and can be distributed via email or pushed into a database.

Audit your Knowledge

VisiRule includes a Truth Table Generator to show the effect of your logic.

Easy to Maintain


The Analytics component shows how a chart is used and by whom. You can use the analysis to help you when you want to update the chart.

Validate and Test

The AutoAudit test harness allows charts to be run using files of test data. The results can be compared with approved or previous results.

Expert System Deployment

Expert systems allow human knowledge and expertise to guide through complpex processes and proedures in a way an expert would proceed. VisiRule allows expert systems to be quickly built and deployed in various ways ranging from light profile HTML/JS client-side deployment through to a powerful server-side rules-based engine.
