These bots keep your team up-to-date with info from other apps so you don't need to jump back and forth. Notification bots watch what's happening in other apps and send any updates to Slack, and they're fairly easy to make. These are perfect for automatically answering questions that tend to come up often on Slack. Reply bots respond when someone uses a specific phrase, and are the easiest bots to make. How hard will it be? It depends on what you want your bot to do.
You can build a Slackbot right now, in just a few minutes, without any code. Slackbots are handy robot assistants that hang out in Slack, wait for commands, then find or create the thing you need.
