How to Build an AI Regex Generator with AI Pass SDK

Build a regex generator that developers will love — and earn 50% commission on every pattern they generate.

What You'll Build

A web tool where users describe patterns in plain English and get working regex with explanations.

Prerequisites

Sign up at aipass.one
Developer Dashboard → OAuth2 Clients → create client → copy Client ID

Step 1: SDK Setup

<!DOCTYPE html>
<html>
<head>
  <title>AI Regex Generator</title>
  <link href="https://aipass.one/aipass-ui.css" rel="stylesheet">
</head>
<body>
  <script src="https://aipass.one/aipass-sdk.js"></script>
  <script>
    AiPass.initialize({
      clientId: 'YOUR_CLIENT_ID',
      requireLogin: true,
      darkMode: true
    });
  </script>
</body>
</html>

Step 2: Interface

<div style="max-width: 700px; margin: 40px auto; padding: 20px;">
  <h1>🔍 AI Regex Generator</h1>
  <textarea id="description" placeholder="Describe what you want to match (e.g., 'email addresses ending in .edu')" rows="3" style="width:100%;"></textarea>
  <select id="lang" style="width:100%; margin: 10px 0;">
    <option value="JavaScript">JavaScript</option>
    <option value="Python">Python</option>
    <option value="Java">Java</option>
    <option value="Go">Go</option>
    <option value="PHP">PHP</option>
  </select>
  <button onclick="generate()" style="width:100%; padding:12px;">Generate Regex</button>
  <pre id="result" style="margin-top: 20px; background: #1a1a2e; color: #eee; padding: 20px; border-radius: 8px; overflow-x: auto;"></pre>
</div>

Step 3: AI Logic

async function generate() {
  const desc = document.getElementById('description').value;
  const lang = document.getElementById('lang').value;
  const resultEl = document.getElementById('result');
  resultEl.textContent = 'Generating regex...';

  try {
    const r = await AiPass.generateCompletion({
      model: 'gpt-5-mini',
      temperature: 1,
      max_tokens: 16000,
      messages: [
        {
          role: 'system',
          content: `You are a regex expert. Given a description, provide:\n1. The regex pattern (for ${lang})\n2. A breakdown explaining each part\n3. 3 examples that match\n4. 2 examples that don't match\nFormat clearly with headers.`
        },
        { role: 'user', content: desc }
      ]
    });
    resultEl.textContent = r.choices[0].message.content;
  } catch (err) {
    resultEl.textContent = 'Error. Please try again.';
  }
}

Always include temperature: 1 and max_tokens: 16000 in generateCompletion calls.

Step 4: Deploy

Option A — Self-host: GitHub Pages, Netlify, Vercel, or your own server.

Option B — AI Pass catalog: Publish on AI Pass. Use the </> button to get embed code.
