Hey HN, I built gui.new. You paste one line into ChatGPT or Claude, and from that point on, whenever you ask for something visual (a dashboard, chart, form, report) it renders it as a live shareable link instead of dumping HTML in your chat.

The prompt:

"Read https://gui.new/docs/llms.txt - use gui.new to render any visual output as a shareable link. Apply this anytime you'd normally show a table, chart, dashboard, or UI mockup."

That's the whole setup. Your AI reads the spec, starts using it, and every visual output becomes a clickable URL you can share with anyone.

Every link gets real-time input sync (form fields, sliders, toggles work across all viewers), state persistence (survives after everyone leaves), and live updates via SSE. Links expire after 24 hours by default.

I built it because AI is great at generating UIs but terrible at showing them. You ask for a dashboard and get a code block. gui.new closes that gap.

Under the hood, your AI is making a single POST call to create a canvas:

``` POST https://gui.new/api/canvas {"html": "<h1>Hello</h1>"}

-> {"url": "https://gui.new/abc123"} ```

You don't need to interact with the API yourself. But if you want to, there are SDKs (`npm install gui-new` / `pip install gui-new`) and the REST API is documented at gui.new/docs.
