This is a chatbot I created to demonstrate two main concepts: Scanning inputs, and returning random responses. With this, you can help the chatbot build its intelligence by adding a variety of acceptable inputs and relative responses. The program will randomly choose from those responses. Written and tested in Visual Studio 2017.
The dialog form is where you will converse with Jarvis. The top field is an input textbox. The Jarvis responses are in a form label that gets updated. The full project: VS_Project.zip
