Personal AI Assistant is a modular AI agent built in Python to deliver conversational chat, context-aware memory, and automated task execution. It features a plugin system for web browsing, file management, email sending, and calendar scheduling. Backed by OpenAI or local language models and SQLite-based memory storage, it preserves conversation history and adapts responses over time. Developers can extend capabilities with custom modules, creating a tailored assistant for productivity, research, or home automation.
