rohit1911-code/Rule-Based-AI-Chatbot — reverse-engineered prompt

Build me a simple Python chatbot called DecodeBot that runs in the terminal and feels friendly and polished. I want it to use basic rule based logic, not machine learning, so it should recognize common phrases like hello, who are you, how are you, help, time, date, motivate, joke, study tips, exam tips, thanks, and bye.

Give it a clean welcome screen, a continuous chat loop, and slightly varied responses so it does not sound identical every time. It should show the current date and local time when asked, give motivational quotes and programming jokes, and offer useful study and exam advice. Please keep a timestamped chat history in a text file, count how many messages were exchanged in the session, and show a short summary when the user exits.

Make it easy to run, readable, and safe so weird input does not crash it. Use only standard Python if possible.
