I am considering creating an SMS chatbot to facilitate productive co-parenting between divorced couples. I am looking at SMS because it is the most common mode of communication for my target audience and would not require a pre-existing mobile app / download. (Great for the user and reduces development and operational costs significantly).
Some downsides came to mind quickly. I will not be able to use a sophisticated interface to interact with the user and it will cost $0.001 per message if I use something like Twilio.
Does anyone here have any experience making an SMS chatbot or have any thoughts on my concerns?
