📖 About

AI Dev Assistant was built to simplify common developer workflows by providing focused AI-powered utilities instead of relying on generic chatbot interfaces.

The application currently includes two productivity tools:

• ✍️ AI Text Rephraser — Rewrite text in different tones while preserving its meaning.
• 🧠 Commit Message Generator — Generate clean Conventional Commit messages from natural language descriptions.

Authenticated users also have access to a personal history dashboard that stores their most recent AI generations for quick reference.

🏗️ System Architecture

The project follows a decoupled full-stack architecture where the frontend communicates with a REST API responsible for authentication, AI orchestration, and persistent history management before interacting with the Groq LLM.

Architecture Overview

• Frontend (Next.js) — User interface and client-side interactions.
• Backend (Express.js) — Authentication, AI endpoints, request validation, and history management.
• MongoDB — Stores users and request history.
• Groq API — Generates AI responses for text rephrasing and commit generation.
• JWT Authentication — Secures protected endpoints and user sessions.
