Big Numbers, Inc. provides a read-only personal finance app for iOS and a read-only Grok connector. We do not move money, issue cards, or act as your bank.
Grok subscription
Big Numbers for Grok is sold on Whop. We bill the same unit Plaid bills us: a linked bank is one login at one institution, not each checking or card account under that login.
- Personal: $9.99 / month, 1 bank. 7-day trial.
- Plus: $19.99 / month, 5 banks.
- Pro: $39.99 / month, 10 banks. Hard ceiling is 10 banks.
Cancel anytime on Whop. Canceling freezes new links and Grok access. Remove banks on the manage page if you want Plaid connections torn down.
What Grok can do
Approval installs the Grok connector. Subscribe on Whop and link banks on Manage before Grok can see balances or transactions. Grok cannot send payments, change your bank login, or add banks without you.
iOS app
The App Store app is a spending tracker. Bank connections use Plaid (and historically Teller). Use of those providers is also subject to their terms.
