Introduction
AI Customer Support Chatbots are intelligent software agents designed to interact with customers in real time. Using natural language processing, machine learning, and increasingly multimodal capabilities, these chatbots can resolve inquiries, provide product guidance, and escalate complex issues when necessary. By automating routine support interactions, companies can enhance efficiency, reduce wait times, and provide 24/7 assistance.
AI chatbots are critical due to growing customer expectations for instant support, higher volumes of support requests, and the need for personalized, consistent experiences.
