The UI for AI · always-on desktop layer

Your AI stops typing.
It starts building.

ARLI is a warm, always-on layer of your desktop where your agents render real, interactive software — a listings board, a player, a brief — the moment it's useful. Often before you ask.

built for Claude, Codex & any MCP client
Just-in-time UI

Don't get a bulleted list. Get the working thing — and sometimes you don't even have to ask.

See it

What shows up.

Each of these is a real window ARLI drew — summoned by one line, or by nothing at all. Not a screenshot of a feature list. The actual interface.

How it works

Ask once. Sometimes don't ask at all.

ARLI runs quietly in the background. When an agent has something worth showing, it draws it — natively, just in time — then clears it away.

connect

Agents plug in over MCP

Claude, Codex, or any MCP client calls ARLI's tools — spawn_window, write_thought. No SDK to learn.

render

They build the interface

Listings, a player, a brief, a control surface — composed for the moment, not crammed into a chat bubble.

dismiss

The window clears itself

Each lives exactly as long as it's relevant, then goes. The layer is always on; the clutter never is.
