Give Your Python AI Agent Persistent Memory with One JSON File

A simple yet powerful AI agent can be built in Python, giving it the ability to remember conversations and utilize tools like a calculator or web search. The agent's persistent memory is ingeniously managed with a single JSON file, allowing it to recall previous interactions even after the program restarts. By connecting to a large language model via an API, the agent intelligently decides whether to answer a query directly or first use one of its tools. The entire system is structured around three core Python classes that handle memory, tool management, and the agent's decision-making flow.
