A BotBuilder software-development kit (SDK) is available on GitHub under an open-source MIT license. These bots can be implemented into a variety of applications, including Slack or Telegram or even email. “Bots are like new applications,” Microsoft chief executive Satya Nadella said. “And digital assistants are meta apps, or like the new browsers. And intelligence is infused into all of your interactions. That’s the rich platform that we have.”
