ChatBot with AppInventor

Hi everyone, I have started building a ChatBot, only I have some doubts about the implementation. My ChatBot works as a Vodafone TOBi or any other online assistant. Recognize non-speech text only (I DO NOT use SpeechToText)
Can you tell me if there is any existing project where to get ideas?

Welcome Ciro.

A search of the community shows chat bot discussions. Use the magnifying glass in the upper right corner of the Community form to search.

Here is something similar HOW TO: Program the native SpeechRecognizer for Continuous Dictation and to do things although it does use a Speech Recognizer. No problem, just use a TextBox and type in it instead of the SR options.
