🧠 How It Works

1. Load Responses: Predefined responses from responses.json and any previously learned responses from learned_responses.json.
2. User Input: Chatbot receives input via CLI.
3. Sentiment Analysis: Detects user mood (positive, negative, neutral) using TextBlob.
4. Fuzzy Matching: Searches for the closest known question to provide a relevant answer.
5. Learning: If no match exists, chatbot asks the user for a new response and saves it for future use.
6. Emoji Feedback: Adds emoji depending on sentiment for personalized replies.

🔒 Notes

• Always keep learned_responses.json to persist chatbot knowledge.
• The bot’s learning is case-insensitive and stores responses in lowercase.
• Predefined responses are stored in responses.json and can be edited manually.
