poorvabhonde6-svg/CodeAlpha_FAQChatbot — reverse-engineered prompt

Build me a polished AI FAQ chatbot web app called NeuroNova AI for an internship portfolio project. It should run locally with a small Flask backend and a clean HTML, CSS, and JavaScript frontend.

The chatbot should answer user questions from an FAQ CSV using smart matching, not just exact keyword matching. Make the chat feel modern and smooth, with a SaaS style interface, message bubbles, suggestion buttons, and a friendly empty state. Add voice input so the user can speak a question, and speech output so the bot can read replies aloud.

Please include light and dark mode, saved chat history in the browser, a clear chat button, and a WhatsApp share option for sharing a response or chat. The UI should feel interactive and portfolio ready, with responsive styling for mobile and desktop.

Set up the Flask API, connect it to the frontend, and include simple run instructions. Look up current docs online if you need to.
