Mohanakoduru/AI_Customer_Support_Chatbot — reverse-engineered prompt

Build me an AI customer support chatbot for a small business demo.

I want it to look and feel like WhatsApp, with chat bubbles for the customer and the bot, a nice fixed background, and a clean modern layout. The user should be able to type a question, press Enter to send, and use Shift plus Enter for a new line.

The bot should answer business FAQ questions using a local FAQ text file and semantic search, so it can work for different businesses like a restaurant, shop, or service company. It should use free or no paid APIs where possible, with local embeddings for search and Groq free tier for the AI response. Add basic moderation so unsafe or inappropriate messages don’t get answered normally.

Make it as a Python Streamlit app, with the chat clearing when the page refreshes or the app closes. Include the needed setup files and clear instructions for adding FAQs and the API key.
