I've been using that app Everweave on my phone, it gives you like 30 free messages and has the DnD 5e system in it to pretty much be a virtual AI DM.
So far it has let me: Murder and steal, pick up a chick at the tavern, just break on someone's house and rob them, more than I can remember over the course of a few months.
Limited classes and races but it's free and interesting.
