If you're here, you're probably looking for the newer project with a similar name, AssumeZero Bot.
This is a Facebook Messenger bot written using Node.js. It allows users to access past messages from a large group chat with a variety of commands. In addition, it can generate new messages using Markov chains and the past chat history of a given user. It is named for the group chat that inspired it, Assume Zero Brain Power.
Passing a date will prompt the bot to locate a message written at that date. If two dates are provided, it will search for a message in that range of dates. To find a message from a specific person, use Yo [name]. These two command types can be combined to find messages from a specific person on a given date or within a range of dates.
To generate a fictional message from a person's chat history using Markov chains, use Yo [name]bot. A message that doesn't trigger any commands will simply return a random message from the entire history of the chat.
