How to add your card to Grok and subscribe

Grok plans are bought on grok.com. Card number, expiry, CVC and billing address are in your card email.

Some plans are half price for the first month and full price after that. Before the renewal date, keep the full price plus the $1 fee on the card — this is the most common reason Grok charges fail.
Subscriptions bought in the iPhone or Android app go through Apple or Google Play and cannot use this card. Subscribe on the web.

Steps

  1. 1

    Check the plans

    Open grok.com/supergrok in a browser. The screenshot shows Plus / Premium / Super / Ultra in CAD (opened in Canada); plan names and prices are whatever the page shows you.

Common reasons it fails

Why Grok / xAI charges on our cards failed over the last 60 days (share of failed charges):

  • About 86%: not enough balance — mostly the full-price second month after a half-price first month.
  • About 12%: the card was already cancelled (Blocked) and the old card kept being charged. Switch cards in your grok.com account settings.
  • About 2%: wrong expiry date.
If a charge fails, top up first and then retry once — don’t keep clicking. Every charge costs $1, failed ones too (at most 3 failed-charge fees per card per month). Top-ups usually arrive within 5–10 minutes and the card number stays the same.
