Equa-AI 📐🤖

Equa-AI is an intelligent mobile application powered by a robust backend that allows users to capture images of handwritten or printed mathematical equations and instantly receive step-by-step solutions. Utilizing Google's advanced Gemini 1.5 Flash vision model, Equa-AI accurately recognizes complex expressions and renders them beautifully in LaTeX.

✨ Features

• 📸 Image Recognition: Seamlessly process images containing mathematical equations.
• 🧠 AI-Powered Solving: Get accurate, step-by-step solutions powered by Google Gemini.
• ✍️ LaTeX Rendering: Beautifully formatted mathematical output using MathJax and SVG.
• 📱 Cross-Platform: Built with React Native and Expo for a smooth iOS and Android experience.
• ⚡ Fast Backend: High-performance API built with FastAPI.

🛠️ Tech Stack

Frontend

• Framework: React Native with Expo
• Styling: NativeWind (TailwindCSS)
• Math Rendering: react-native-mathjax-html-to-svg
• Navigation: React Navigation

Backend

• Framework: FastAPI (Python)
• AI Model: Google Gemini API (gemini-1.5-flash)
• Server: Uvicorn

🚀 Getting Started

Prerequisites

• Node.js and npm/yarn
• Python 3.8+
• Expo CLI
• Google Gemini API Key

Backend Setup

1. Navigate to the backend directory:

   cd backend

2. Create and activate a virtual environment (optional but recommended):

   python -m venv venv
   source venv/bin/activate  # On Windows use `venv\Scripts\activate`

3. Install dependencies:

   pip install -r requirements.txt

4. Create a .env file in the backend directory and add your Gemini API key:

   GEMINI_API_KEY=your_google_gemini_api_key_here

5. Start the backend server:

   python main.py
   # Or using uvicorn: uvicorn main:app --reload

   The API will be available at http://localhost:8000.

Frontend Setup

1. Navigate to the frontend directory:

   cd equa-ai

2. Install dependencies:

   npm install

3. Update the API endpoint in the frontend configuration to point to your local backend (if necessary).
4. Start the Expo development server:

   npm start
   # or
   npx expo start

5. Scan the QR code with the Expo Go app on your phone, or run on an emulator/simulator.

📡 API Endpoints

• GET / - Health check and status
• POST /solve - Upload an image to get recognized math and step-by-step solutions
• GET /health - API monitoring endpoint
