I Created a Simple Tool to Instantly Preview HTML Generated by ChatGPT

Introduction

ChatGPT has become a powerful ally for generating HTML and other code snippets. However, if you’ve ever tried working with the HTML code it outputs, you might have run into a small but persistent annoyance.

To preview the HTML, we typically need to:

・Manually create an .html file
・Open it in a text editor and paste in the code
・Save the file and open it in a browser
・Repeat this every time we make a small change

This process may not be complex, but doing it repeatedly can become surprisingly tedious.

A Simple Solution

To reduce that friction, I created a small web tool that lets you paste HTML code and instantly render it in the browser—without saving any files.

How to Use

1. Copy the HTML code generated by ChatGPT
2. Paste it into the input field on the tool’s page
3. Click the “Render” button

That’s it. The entire page will be temporarily replaced with your HTML content. No need to create or save any files manually.

Error Handling Is Friendly Too

This tool uses document.write() to replace the document with your input. If your code contains syntax errors, the browser will usually provide helpful messages, and the line numbers in the console log remain consistent with your input. This makes debugging a bit easier as well.

Conclusion

Opening and saving HTML files manually each time you want to make a change might seem trivial at first. But over time, it adds up and slows you down—like a slow-draining battery.

With this tool, I hope to make your workflow just a little more efficient and enjoyable.

It's available on GitHub, so I'd be happy if you could download it and place it on your desktop.
