Two ways to play

Chat, or give it a goal.

Chat

Talk back and forth

Ask anything. Sandbox answers, then waits for your next message. It can still read your files, browse the web, and use your Mac apps to answer properly.

Goal

Hand off a whole job

Describe the finished result. Sandbox plans it, works through every step on its own, checks its work, and tells you when it's done. It keeps going while you do something else.

Safe by design

Playful on the outside. Careful underneath.

The Lifeguard

Asks before risky actions

Deleting, sending, paying, or changing system settings waits for your OK. Allow it right from the notification.

The Tide Log

Undo for file changes

See exactly what changed in every file, side by side, and rewind one change or the whole sandcastle.

Stays on your Mac

Local models, no account

The AI runs on your Mac's own chip. Nothing you type or show it is sent anywhere.

The Bucket

It remembers

Tell it your preferences once. Every chat and goal starts knowing them, and you can edit the notes any time.

Periscope and Toybox

Browser and Mac apps

It can research on the web in its own browser and work with Mail, Calendar, Reminders, and Finder.

Sand Printer

Makes pictures and video

Create images and short video clips right on your Mac, and see them in the chat.
