I need an automated chatbot that can handle customer support queries directly inside our existing mobile app. The bot should greet users, understand common questions about our services, and deliver accurate, friendly responses without human intervention. Where answers fall outside its knowledge base, it must smoothly escalate to our live support queue so no conversation is ever dropped. Key deliverables: • Dialog flow design covering all current FAQs, account issues, and order-status checks • Natural-language understanding setup (Dialogflow, IBM Watson, or similar) with intent and entity training • Seamless SDK integration for both iOS and Android versions of the app • Simple admin panel or JSON file for my team to update responses without code changes • Handover mechanism that flags unresolved chats for live agents, preserving the full transcript Acceptance criteria: • At least 90 % of test questions answered correctly during user-acceptance testing • Response time under one second on a standard 4G connection • No crashes or noticeable lag within the app after integration Source code, documentation, and a short video walkthrough should be included at hand-off so my developers can maintain the solution long-term.
