I'm working on a chat bot that will look like this (watch the video): https://goo.gl/OsSdb3
I still have a lot of work to do, and I'll wait for Facebook approval to make this available to everyone which might take weeks.
I have countless number of ideas, it can be something like your virtual coach who suggests problems to solve or editorials/algorithms to read, which remembers your history and suggests something suitable for you.
In the above page you can subscribe to get an email when this is live to everyone, but what I need the most right now, is ideas. Please if you have any idea, you can write it in the above link or just write it in a comment here. Thanks in advance.
