Discov is a Discord bot that tracks messages of server members and can generate messages based on a users data through a Markov chain. You can also request and/or delete your data stored by the bot.
Discov keeps it's data in memory and persists it in a json file and does therefore not scale very well, so it's best suited for private use.
