stackblitz/bolt.new ? reverse-engineered prompt

I want to build an AI-powered web development tool that runs entirely in the browser, with no local setup required. The main interface should be a chat window where a user can describe an application they want to build, and the AI will create it for them in a live environment.

The key is that this AI should be able to do everything a real developer can, right in the browser. It needs to install packages, run a Node.js server, edit files, and even use a terminal. The user should see a live preview of the app they're building and be able to give follow-up prompts to make changes, like "change the background to dark gray" or "add a contact form."

Essentially, it's a complete, self-contained development sandbox that lets someone go from an idea to a deployed website just by chatting. Please use a modern full-stack setup with TypeScript for this.
