Build Chatbot That Remembers Conversations | Day 11 of 30 Days of AI Coding Challenge

Welcome to Day 11 of the 30 Days of AI Coding Challenge 🚀

Yesterday, our chatbot could show chat history — but the AI didn’t remember it.

If an AI cannot remember the conversation, it’s not a chatbot — it’s just a fancy text box.

Today, we fix that and make the chatbot feel complete.

🧠 What You’ll Build Today:

A chatbot that:
Remembers conversation context (history passed to LLM)
Shows a welcome message on first load
Displays conversation stats in the sidebar
Allows users to clear chat history

A more polished and user-friendly AI app
