Saw it on HN, it looks like a do-it-all hubot like service with little to no configuration for Slack.
On the main site it reads:
"Turbocharge your Slack experience by connecting to a full suite of commands"
It integrates with github, uber, mail services, airplane arrival schedules, etc etc
Sounds super fun and for all you Slack junkies out there might become an integral part of your "never-tabbing-out-of-slack" experience?
