There are a lot of bots coming on the market over the past year. If you are not aware bots are a computer program you can easily configure to reply to repetitive questions. The bots normally work by you entering in the questions and answers to each question. This comes in really handy when dealing with something such as getting asked about something that is already covered elsewhere, Perhaps on your teacher page or the syllabus.
There are a lot of companies offering these bots, but most are targeted towards business purposes and not for education. Some are very expensive to just see if they will work for your needs.
I’ve been working with putting together chat bots for educator use and Collect Chat is showing the most promise right now. There are some other good ones too, but the great thing about collect chat for the educational user is the templates designed specifically for educators.
Plus they give you a free version that is good enough to get started and ensure your students are ready to speak bot.
