***IMPORTANT MUST READ*** Press see inside before starting the project if you want to be able to import and export memory. Do that by right clicking on the lists and pressing export if you want to save, and import if you want to load. Press space to begin, then type a word. If the bot knows the word, then it will answer you, but if it does not know the word, then it will ask you how to type a response to that word. Type a semicolon at the beginning or end of a response to make it a question. To add answers to the question, press space, type the word that you programmed, then enter, and then answer the question with anything. Now enter the answer you want to add. Now add the robots answer to that answer.
This is my first artificial intelligence project, and I think that it is the only working one on scratch. Try to teach it English.
