AI-EGENT
An open-source deep research AI agent powered by LangChain, FastAPI, and free AI APIs.

Overview
AI-EGENT provides production-ready APIs to easily build chat applications like ChatGPT or Claude. It features multi-turn chat sessions, persistent user history, image understanding, and robust user authentication over a PostgreSQL database.
The Problem
Building AI applications from scratch requires setting up complex session tracking, database schemas, and LLM integrations.
The Solution
Created a ready-to-use FastAPI backend integrating LangChain with free APIs (Groq), handling DB migrations (Alembic), and managing secure JWT auth.
