HubSpot’s chatbot is a conversational tool designed to automate customer interactions on websites or Facebook Messenger. Its main purpose is to qualify leads, book meetings, and handle support requests by routing inquiries to the appropriate teams and collecting visitor information. Key features include rule-based flows, live chat integration, task-specific bots for marketing or operations, and, with upgrades, conversational AI that draws from a knowledge base to provide automated, human-like responses and manage support even when staff are offline.
