Alterday is a life simulation you play.

For when you want to understand or change something about how you live, on your own or with someone who helps you. You play; the assistant or professional you choose learns what you actually do.

Invitation only. No invitation yet? Ask for one.

How it works

Play whenever you want.
Get your link.
Give it to your assistant, or to anyone who helps you: a therapist, a coach, a doctor.

Your assistant (ChatGPT, Claude, Muse and others) decides what to ask you, and when. Come back whenever you like: your link shows what changed.

Why

Much of how we live happens in small everyday choices that are hard to put into words. Alterday lets you show them, so you, and the people and tools that help you, can see them and know yourself better over time.

Alterday for professionals

For therapists, coaches, doctors and researchers who work with people. We're building it with the people who will use it.
