How to Use the AI HTML Preview Tool

Getting Started

This tool lets you instantly preview HTML code generated by AI assistants like ChatGPT, Claude, Gemini, or any other source. No signup or installation required.

Step-by-Step Guide

  1. Copy HTML code from your AI assistant or any source.
  2. Go to the editor by visiting the home page.
  3. Paste your code into the text area. You can use the "Paste" button to paste from your clipboard, or paste manually with Ctrl+V / Cmd+V.
  4. Click "Preview" or press Ctrl+Enter (Cmd+Enter on Mac) to instantly render the HTML.
  5. After previewing, use the "Save" button to download the HTML file, or click "Back" to return to the editor.
  6. Click "Clean" to clear the editor and start over.

Supported Content

The preview supports full HTML documents including:

  1. HTML markup with inline or embedded CSS styles
  2. JavaScript code within <script> tags
  3. External resources loaded via CDN links
  4. Responsive layouts and media queries

Keyboard Shortcuts

  1. Ctrl+Enter / Cmd+Enter — Preview your HTML instantly.

Tips

  1. You can paste code wrapped in ```html code blocks — the tool will automatically strip the markdown formatting.
  2. For best results, paste a complete HTML document including the <html>, <head>, and <body> tags.
  3. The preview renders inline on the same page. Click "Back" to return to the editor with your code still intact.
  4. Your code never leaves your browser — the preview is rendered entirely client-side.
