As of right now, the only Bots available to add on Skype are Bing Music, Bing News, Bing Images, Getty Images and Build Bot (which is mostly centered around the Build conference).
The way you add a bot is the same way you'd add a contact; indeed, the Add Contact screen in Skype now has two categories: People and Bots.If you're looking for a more complicated answer, it's probably easier to just make a call or look up your answer on Google (or Bing, naturally).Of course, it's still early days yet for Microsoft's AI strategy and we get the feeling that future bots will be a lot more intelligent.For example, with the Bing Music bot, typing in "Hello" would bring up Adele's song (a link to her You Tube video, it looks like) rather than polite small talk.A "Hi" in Bing News brought up articles with the word "Hi" in it. " it responded with different lunch hours instead of what was on the menu. You might ask around or try this thing called the internet." Cheeky.Earlier today, Microsoft announced that it would be integrating chat bots into Skype, thus allowing you to have quick conversations with a variety of businesses and services.
