X. Build apps and test in Grok X directly

I wrote a single prompt.

Grok X wrote the code, helped me debug it, and tested it live all in one place.

Anyone can do this now.

You don’t even need VS Code.

Prompt:

“Create a web app where users can upload an image and get a summary of the text content. Use HTML/CSS/JS and show output directly beautifully with a modern design app.”
