Sunlight is a mix of every colour. As it passes through the air, tiny gas molecules scatter short blue wavelengths much more than long red ones, an effect called . So blue light reaches your eyes from every part of the sky at once.

One app.
Three ways to work.

Switch with ⌘1, ⌘2 and ⌘3. Projects are shared across all three, so nothing needs explaining twice.

01 / Chat

Every answer leads somewhere.

Branch from any phrase, ask up to four models at once, and get charts and tables when a picture is clearer.

…an effect called Rayleigh scattering, so blue light…
Fork ▾ExplainGo deeper
02 / Code

Infinite tries. One clean history.

Describe an app or open a folder. It runs beside the chat, and every change is a save point you can go back to.

03 / Assistant

Always working. Always asks first.

Assistants you message like contacts, with their own memory and schedules. They ask before doing anything you haven't allowed.
