This is a simple Python-based chat assistant powered by OpenAI's GPT and function calling capabilities. It supports three built-in functions:

1. Mortgage Calculator
2. Product Database Search
3. Currency Conversion (using Exchangerate-API – API key required)

• Conversational CLI interface
• Automatic function calling using OpenAI's latest API
• Real-time currency conversion without API key
• Clean modular code using Helpers.py

Here are five example queries to demonstrate function calling:

1. "How much does an Iphone cost?"
   → Calls search_product_database

2. "What would be my monthly rate on that Iphone, if I bought with 10% interest for a 5 year period?"
   → Calls calculate_mortgage

3. "How about for a 3 year period, with 5% interest?"
   → Calls calculate_mortgage

4. "Convert that amount to Georgian Lari."
   → Calls currency_converter

5. "Now convert that amount to Euro."
   → Calls currency_converter
