I made a little thing using AI. It's called Pterocos.

It’s a browser-based code editor for HTML, CSS, and JavaScript with AI Chat — kind of like CodePen or JSFiddle, but with a few things make it cool.

A browser-based coding environment for front-end developers. Write HTML, CSS, and JS with a VS Code-grade editor (Monaco), live preview, SCSS/TypeScript/Babel support, and an AI chat assistant for debugging and suggestions. All projects save to local storage. Free forever – no account needed.
