Getting started

How you join Theorem, how you sign in with a link sent to your email, and what you have once you are in.

You join Theorem in one of two ways, and you always sign in with a link sent to your own email address. There is no password.

Joining

• With an invite link. It opens a page called Join Theorem. Give your email address and press Send me a link.
• With a team's invitation. A team's leader invited the address you use. You get a short email from Theorem that names the team and who invited you. Go to theorem.sa, sign in with that same address, and your account is made. The invitation is then waiting for you under Teams.

Without either, the sign-in page says that you need an invite link to join.

Signing in

1. Go to theorem.sa and give your email address.
2. Press Send me a link. The page says Check your email.
3. Open the link in the email. It works once, for 15 minutes.
4. Press Sign in on the page it opens.

The first time, Theorem asks What's your name? Your name is how the people in your teams see you, and you need one to start or join a team. You can change it later in Settings.

You stay signed in on that device for 30 days after you last used Theorem. To sign out, open the menu under your name at the foot of the sidebar and choose Sign out.

The page answers the same way whether or not an address has an account, so it never tells anyone who uses Theorem. One address can be sent 5 links an hour.

What you have once you are in

The sidebar has New chat, Search, Drive, and your chats. Mail and Calendar appear once a team gives you an address. Until then, those pages say that a mailbox, or a calendar, comes with a team.

The menu under your name leads to:

To begin, press New chat and write to the assistant (Chatting with the assistant).
