NS-bot-x is a Discord bot. He answers when you talk to him. He can approximately translate sentences from any language to any other language, say things in voice channels, create polls, insult or compliment people, and do a lot of other cool stuff.
Add your own API keys in bot.js ;)
I use Heroku to host my bot (this is why the Procfile is present), it is basically free for non-intensive usage.
