Develop a working prototype of an AI chatbot that answers common customer questions using approved business information. The bot should be helpful but cautious, clearly handle uncertainty, and provide a path to human support when a question falls outside its knowledge or involves sensitive account details. The successful freelancer will be expected to work independently, share progress at agreed checkpoints, and raise questions early when a requirement needs clarification. All submitted work should be original, well organized, and ready for practical use after reasonable review.
