How to Use This Tool

1. Generate a full web app using AI

Copy one of these prompts into your favourite AI assistant:

Gemini / ChatGPT / Copilot:
"Build a complete, self-contained HTML/CSS/JS web application with a modern UI. Include interactive features, responsive design, and no external dependencies. Add local storage or demo data. Make it a functional dashboard/todo/calculator/crud app. Output only the full HTML file."

2. Paste the code into the editor

Switch to Combined HTML mode and paste the entire output. Or use Split Files for separate HTML/CSS/JS.

3. Click Compile, Preview & Scan

The tool renders your app live and runs a real‑world security audit (XSS, secrets, dangerous patterns).

4. Address vulnerabilities

Use the report table to identify issues, then click Fix All Issues to contact us for a professional security review.
