AI Assistant with Tools and Memory

AI Assistant with Tools and Memory is a Python-based command-line AI application that uses LangChain and LangGraph. It can perform arithmetic operations, provide greetings, generate random numbers, calculate square roots, convert temperatures, give the current day and time, and remember previous conversations.

Users can interact with the AI by typing commands or questions, and the AI will respond using the appropriate tool or chat response.

Features

Arithmetic operations: addition, subtraction, multiplication, division, exponentiation, square root

Utilities: current time, current day, temperature conversion
