Synthia: AI - Prototype is a beginning Artificial Intelligence programmer's dream. Have you ever wondered how a chat bot is created or programmed? Test out this precursor to Synthia: AI and find out. The programming for the artificial intelligence is simple and will construct an If-statement for you based on the rues you give it This program is a stepping stone for the full version of Synthia: AI to be introduced in the coming months to the App Store. This version is a bot that you can program any response to different sets of keywords and if it detects said keywords in your chat it will respond in the way you programmed it to. It can be funny, serious, technical, etc. as long as the bot sees the keyword combinations in any order the bot will know what to say. Two Arrays of keywords separated by an Or: if() && if() && if() || if() && if() && if() { Say(); } This barebones version of Synthia: AI is a great way to test your programming logic, though it will write the program for you, once the bot detects something it should respond to, the program will display the pre-created (at time of adding the rule) if-statement the artificial intelligence behind the bot used to determine what to say. Have fun and enjoy!
