I'm happy to give Tiny Talk 5 out of 5 tacos. I have created a learning tutor for students. It asks students questions about my own course content, lets them answer and gives them feedback. The bot either decides which questions it asks itself or I specify the questions. I trained the chatbot on the basis of a PDF file. The whole thing was extremely easy to create. Oscar then helped me to integrate the bot into an existing e-learning module via API using JS script. This is not a matter of course because it is a special use case. All I can say is: great!
