A Mac with a small, warmly lit wooden door in its notch

A NATIVE MAC APP

Your Mac already
had an attic.

It just needed a door.

Leave files in the notch.
Pick them up in another window.

Come in and try it

Files within reach.
In the space that was already there.

SOMETHING INSIDE THE NOTCH

For that file
you'll need
in a moment.

You're between two windows. Leave the file up top, switch apps and pick it up from the notch.

That's Altillo: a temporary shelf at the top of your Mac.

A Mac. Your turn.

INTERACTIVE DEMO / example data

01 / FILES AND ORDER

Put a file up top.
Carry on.

Move your cursor over the notch to open it. Drag a document onto the shelf, then take it to the destination folder.

On your phone, tap the notch. You can also move files with the buttons.

02 / YOUR DAY

What's next,
within reach.

Check your next meeting, pause your music or see yourself before a call. All in the space up top.

03 / AI

When you're coding,
look up.

Altillo reads your Claude, Codex and eight other providers' usage, and lets you know when your coding agents are waiting on a permission. Try checking your limits or responding to a permission request.

This is a simulated request. No commands run here.

ALTILLO MEANS ATTIC

Leave something upstairs.

Bring it down when you need it.

The idea behind Altillo.

BUILT IN THE OPEN

We're still
getting the place ready.

The shelf, calendar, music controls, mirror, drawer, AI usage for ten providers, live agents and Ask — the on-device assistant — are already implemented in the app. The latest signed, notarized release is on GitHub.

You can follow our progress, read the code or build Altillo from GitHub.
