Built.at← HomeBuilt by chat.
Built.at lets you create, publish, and edit webpages directly from ChatGPT. Describe what you want, then keep changing it in conversation.
Getting started
Connect Built.at to ChatGPT once, then create and update webpages through chat.
Once connected, ask ChatGPT to create a webpage. Describe what you want, open the published link, and keep refining it through chat.
Connection instructions ↗How it works
1. Describe
Describe what you want in ChatGPT. You can ask for a simple page, a full layout, or interactive elements.
2. Publish
Built.at saves the page and gives it a web address. Ordinary page edits publish without a separate deployment step.
3. Iterate
Ask for changes in natural language. ChatGPT can inspect the current page before editing, so you don't need to paste its source back into the conversation.
“Make a page with a big headline and a blue background.”
“Add a contact section.”
“Make the layout work better on mobile.”

Built.at connects through the Model Context Protocol (MCP), which lets ChatGPT inspect and update your Built.at workspace using supported tools.

Publishing and edits
Pages can contain HTML, CSS, JavaScript, and structured data. Existing pages can be patched with version checks to help prevent overwriting newer changes.
For exact connection steps, see the MCP setup guide. Tool capabilities may evolve; the connected server's current inspection response is the authoritative reference for supported operations.
Public roadmap
Built.at is an ongoing experiment in building software through conversation. Follow the ideas, current priorities, and open questions as the platform develops.
