1. On Settings > Billing the AI Credits box shows your balance and Cost per prompt; click Buy credits (or go to /admin/sprwtai/buy-credits). You need the Sprwt AI buy-credits permission.
2. On the AI Wallet page click Add credit and pick a pack - $1, $5, $10, $20, $35, $50 (featured) or $100 - or enter a custom amount (minimum $5) and click Continue.
3. Confirm the purchase. Your card on file is charged the amount plus a 3.5% processing fee, and you see "Credit Added Successfully" with the new balance.

AI credits are consumed by Sprwt's AI features across the admin - creating meal recipes, generating ingredients and recipes, meal images, the Write with AI assistant and automatic menu generation - at the Cost per prompt shown. The Usage report > View link on the Billing page opens the AI balance report.
