Invites

Invite a friend, you both get 7 days of Pro: your link, what counts, and what it gives.

Every account has one. It is on your account page, under Invite friends, and it is the site's address with ?ref=<username> on it. Copy it, or press Share on a phone, and send it to whoever you like.

The links you already share carry it too: Copy link and Share with a friend in the editor's Share sheet, challenge links, the QR code, and a project page's Copy link. You do not have to do anything extra.

Invites are by link only. Mokxi never asks for your friends' email addresses, phone numbers or contacts, and never emails anybody on your behalf.

What counts

All four have to happen:

  1. Your friend opens any page on the site from your link. That leaves a marker on their browser for 30 days.
  2. They make an account. It is written against you, once, and an account can only ever be invited by one person. You cannot invite yourself: not with the same account, not with another address at the same mailbox, and not from a browser you are signed in on.
  3. Their sign-in is confirmed: a GitHub or Google sign-in, or an email address they confirmed from the link we sent.
  4. They save a circuit with at least one part in it to their account.

The order of the last two does not matter. When all four are true, you both get the reward at once, and the editor tells you both.

What it gives

7 days of Pro for you and 7 for your friend. The days go on top of any Pro time you already have from a trial or an earlier invite, so nothing is wasted.

It counts for up to 5 friends, so 35 days of Pro at most. Your link keeps working after that, but a sixth friend does not earn days for either of you. The card shows "2 of 5 friends joined" and the Pro days you have earned.

If you are on a paid plan when a reward lands, your days are saved and start when that plan ends, so you do not lose them while you are already paying. The card says how many are waiting.

The Pro trial is separate. If you start it after invite days, it runs after them.

Who takes part

Everyone with an account, except accounts in a class as a student. A student in a class has no invite link, sees no invite offer, and neither earns nor gives the reward, which keeps school use clean. Joining a class as a student deletes any record of the invite the account came in on. An account a parent or guardian consented to for a child under 13 takes no part either.

Before this

Until September 28, 2026, the reward was a month of Pro for every three people who joined. Anything earned that way is still yours: a month waiting on your account goes on your first Pro or student checkout, and a credit on a paying account comes off the next bill, as the card says.

Where to see it

The Invite friends card on your account page carries the link, the progress and the days earned.

The learning game's weekly leaderboard has a friends board fed by the same link: people who came in through your link, and whoever's link you came in through. See the daily challenge and the leaderboard.
