The average cost of chatbot software for a website can range from $30 per month to $1000 per month, depending on the complexity and features required. Others charge based on the number of interactions or user sessions, while some chatbot-building platforms provide free or inexpensive subscriptions. Chatbots are commonly used for customer service, lead generation, and e-commerce. While typical customer care activities can be handled by chatbots, they cannot fully replace interaction with humans.
