Developers, brands, and Kik can create bots to communicate with any Kik user who has opted to start a conversation with them. In some cases, a Kik user might mention a bot to you in a chat. If you subsequently engage with that bot, it will be added to your friend list and will have the ability to chat with you in Kik. You can block or stop chatting with bots any time by following the instructions here. (Earlier versions of bots were called Promoted Chats).
