🔥 Perfect — here’s a complete README.md for your new subdomain ai-tools.30tools.com, explaining its purpose, structure, tech stack, contribution guide, and OpenAI integration.

This version is written in a clean, developer-friendly tone with a touch of product polish — ideal for GitHub or internal documentation.

ai-tools.30tools.com is a collection of lightweight, open-source AI-powered utilities built using the OpenAI API, designed to make content creation, coding, writing, and ideation faster and smarter.

Each tool lives independently but shares a consistent design system, architecture, and user experience — powered by Next.js + shadcn/ui + Tailwind CSS.

⚡️ One platform. Many tiny AI tools. Fast, elegant, and instantly usable — powered by OpenAI.

ai-tools.30tools.com is part of the 30tools.com ecosystem — a growing library of simple, no-login, instantly usable micro-apps.

This subdomain focuses entirely on AI-powered tools, like:

• 🧠 AI Paraphraser — rewrite text in any tone
• 💬 Tweet Generator — generate catchy tweets from ideas
• ✍️ LinkedIn Formatter — make posts professional and polished
• 💡 Startup Idea Generator — spark ideas instantly
• 🧩 Code Explainer — turn any snippet into simple English
• 📚 Quiz Maker — convert text into Q&A
• 🔍 Summarizer — TL;DR anything

All AI tools follow a unified design language defined in:

📁 /config/design.json

• Rounded corners (rounded-2xl)
• Soft shadows & white cards
• Accent blue theme (#3b82f6)
• Framer Motion for subtle animations
• Reusable layout: Header → Input → Output

This ensures all tools feel cohesive and branded under the 30tools identity.

Create a .env.local file in the root directory:

OPENAI_API_KEY=your_openai_api_key_here

You can get your API key from https://platform.openai.com/account/api-keys.

// app/paraphraser/api/route.ts
import { NextResponse } from "next/server";
import OpenAI from "openai";

const client = new OpenAI({ apiKey: process.env.OPENAI_API_KEY! });

export async function POST(req: Request) {
  const { text, tone } = await req.json();

  const prompt = `Rephrase the following text in a ${tone} tone:\n\n${text}`;
  const completion = await client.responses.create({
    model: "gpt-4o-mini",
    input: prompt,
  });

  return NextResponse.json({
    output: completion.output[0].content[0].text,
  });
}

To add a new AI tool:

1. Create a folder under /app/(tools)/your-tool-name/
2. Add a page.tsx for UI
3. Add a api/route.ts for backend logic (using OpenAI API)
4. Follow the design system JSON for consistent look
5. Done ✅

You can use a meta prompt like:

“Using the 30tools design system (from /config/design.json), generate a Next.js page for a tool called ‘AI Summarizer’ with a textarea input, a generate button, and an output card.”

We welcome contributions from developers, designers, and creators!

1. Fork the repo
2. Create a new branch
3. Add your tool (in /app/(tools)/)
4. Run locally → npm run dev
5. Submit a PR

Please ensure your tool:

• Loads instantly
• Uses OpenAI API responsibly
• Follows /config/design.json styling
• Doesn’t store user data

Would you like me to create a “Tool Template Generator” script next — where you can just type npx create-ai-tool paraphraser and it auto-creates the page.tsx, api/route.ts, and meta.json files using your design.json?
