Some bots communicate with users of Internet-based services, via instant messaging (IM), Internet Relay Chat (IRC), or other web interfaces such as Facebook bots and Twitter bots. These chatbots may allow people to ask questions in plain English and then formulate a response. Such bots can often handle reporting weather, zip code information, sports scores, currency or other unit conversions, etc. Others are used for entertainment, such as SmarterChild on AOL Instant Messenger and MSN Messenger.
