Chatbots are tools that reply to people using preset rules or simple learning systems. Many businesses use them on websites and social media to answer common questions. This helps customers get quick replies at any time, even at night. For marketing, chatbots can guide users to products and collect basic details. Still, they can feel cold when answers are too fixed or wrong. Human support is still needed for complex issues. I think chatbots work best as helpers, not replacements. This balance matters for small and large brands today. How do others see their role in service and promotion today?
