-This is a [Next.js](https://nextjs.org) project bootstrapped with [`create-next-app`](https://nextjs.org/docs/app/api-reference/cli/create-next-app).
+# Anything vs Anything

-## Getting Started
+A Next.js application that uses AI to compare any two things and display the results in a table format.

-First, run the development server:
+## Features

+- Compare any two items using AI-powered analysis
+- Optional detailed descriptions for more context
+- Results displayed in a formatted table
+- Responsive design with Tailwind CSS
+- Powered by Replicate AI API
+
+## Setup
+
+1. Clone the repository and install dependencies:
 ```bash
-npm run dev
-# or
-yarn dev
-# or
-pnpm dev
-# or
-bun dev
+npm install
 ```

-Open [http://localhost:3000](http://localhost:3000) with your browser to see the result.
+2. Set up environment variables:
+```bash
+cp .env.example .env.local
+```

-You can start editing the page by modifying `app/page.tsx`. The page auto-updates as you edit the file.
+3. Add your Replicate API token to `.env.local`:
+```
+REPLICATE_API_TOKEN=your_replicate_api_token_here
+REPLICATE_MODEL=meta/llama-2-70b-chat:02e509c789964a7ea8736978a43525956ef40397be9033abf9fd2badfe68c9e3
+```

-This project uses [`next/font`](https://nextjs.org/docs/app/building-your-application/optimizing/fonts) to automatically optimize and load [Geist](https://vercel.com/font), a new font family for Vercel.
+4. Run the development server:
+```bash
+npm run dev
+```

-## Learn More
+5. Open [http://localhost:3000](http://localhost:3000) to view the application.

-To learn more about Next.js, take a look at the following resources:
+## Usage

- [Next.js Documentation](https://nextjs.org/docs) - learn about Next.js features and API.
- [Learn Next.js](https://nextjs.org/learn) - an interactive Next.js tutorial.
+1. Enter two items you want to compare
+2. Optionally add detailed descriptions for more context
+3. Click "Compare Now" to get AI-powered analysis
+4. View the results in a formatted table

-You can check out [the Next.js GitHub repository](https://github.com/vercel/next.js) - your feedback and contributions are welcome!
+## Environment Variables
+
+- `REPLICATE_API_TOKEN`: Your Replicate API token (required)
+- `REPLICATE_MODEL`: The Replicate model to use (optional, defaults to Llama 2 70B)
+
+## Tech Stack
+
+- Next.js 15 with App Router
+- TypeScript
+- Tailwind CSS
+- Replicate AI API
+- React Markdown for table rendering

 ## Deploy on Vercel
