Zendesk, customer service and engagement solutions provider, recently introduced the expansion of its Answer Bot product. Answer Bot is a machine learning tool that helps customers find answers for themselves. It pulls data from the Zendesk Guide knowledge base and suggests articles to help customers solve problems on their own. Answer Bot has been around for a few years. However, Zendesk is expanding the service through integration capabilities through API, SDK, Web Widget, and forms (both email and web).
