AIDA

AIDA is an AI assistant platform that I started to better understand how modern AI applications are built.

Initially, the goal was simple: create a chatbot using OpenAI's API and provide custom context from Firestore. As I kept building, the project naturally grew into something much bigger. Instead of having a single hardcoded chatbot, users can create accounts, manage their own contexts, and build personalized AI assistants around their own knowledge and instructions.

The project has become a playground for learning and implementing real-world concepts such as authentication, authorization, backend architecture, database design, AI integration, and scalable application development.

What AIDA Can Do

AI Conversations

• Chat with an AI assistant powered by OpenAI models
• Generate responses using user-provided context
• Maintain conversation history
• Support personalized assistant behavior

Authentication

• Email & Password Sign In
• Google Sign In
• JWT-based authorization
• OTP verification flow

Context Management

Users can manage their own AI contexts:

• Create, read, update and delete context

These contexts are later used by the AI while generating responses.

User Data

Authenticated users can:

• Save conversations
• Manage and customize contexts
• Access their personalized assistant setup

Guest users can still chat with the AI with default context, but their conversations aren't stored.

Why I Built This

I wanted to understand what actually happens behind AI applications beyond simply calling an API.

While building AIDA, I have been exploring:

• Authentication and authorization
• Firestore database design
• Backend architecture
• REST APIs
• JWT authentication
• Email verification workflows
• Context engineering
• AI application development

The project continues to evolve as I learn new concepts and improve the system.
