How to preview React code from ChatGPT

ChatGPT is great at writing React components and bad at showing you the result. Instead of setting up a project to test its code, render it in your browser in seconds.

The gap between ChatGPT's code and the actual result

When ChatGPT writes a React component, you get a code block, not a working interface. Its built-in canvas can preview some code, but the moment you copy the code out, export the chat, or want to check it days later, you're back to staring at raw JSX. And judging UI code by reading it is like judging a photo by its EXIF data.

Preview ChatGPT's React code in 3 steps

  1. Copy the component from ChatGPT and save it as a file ending in .jsx (or .tsx if it's TypeScript)
  2. Go to dropview.co
  3. Drop the file onto the page and interact with the real, rendered component

A faster iteration loop

This turns ChatGPT into a proper UI workflow: ask for a component, drop the file, see the result, and paste feedback back into the chat ("the button overlaps the header on mobile"). DropView also lets you switch the preview between desktop, tablet, and mobile widths, and compare two versions of a file side by side, which is exactly what you want when ChatGPT gives you revision after revision.

Tips for getting previewable code from ChatGPT

  • Ask for "a single-file React component with a default export". Those render anywhere, including DropView.
  • If the code imports local files (like ./Header), ask ChatGPT to inline everything into one file.
  • Plain HTML output? Save it as .html and drop it in the same way.

Previewing AI-generated React code: common questions

What file extension should I use when saving ChatGPT's code?

Use .jsx for JavaScript React components and .tsx if the code has TypeScript type annotations. If you're not sure, .tsx is the safe choice: it accepts both.

Why does the component render in ChatGPT's canvas but not from the saved file?

The canvas quietly provides a project around the code. Once saved as a standalone file, missing local imports become visible. Ask ChatGPT for a single-file version with a default export and it will render standalone.

Can I compare two versions of a component ChatGPT gave me?

Yes. DropView Pro shows two files side by side, which makes it easy to see exactly what changed between revisions.

Does this work with Claude, Gemini, or Grok code too?

Yes. Any AI-generated React or HTML file works the same way: save it, drop it, see it rendered.
