Auto Recharge keeps AI features working by topping the wallet up automatically. On the AI Wallet page scroll to the Auto Recharge card:

1. Switch Status to On.
2. Enter When balance is below ($) – the threshold (default 5).
3. Choose a Refill amount – $5, $10, $20, $35, $50 or $100 (default $10).
4. Click Save settings. Changes take effect immediately.

How it behaves: every time an AI feature is about to run, Sprwt checks the balance; if it is below your threshold it charges the Refill amount to your card on file (via Stripe, described as Sprwt AI Prompt Credit) and adds it to the wallet before the AI call proceeds. If the charge fails the balance is left as is and the AI call may then fail with the out-of-credits message. Note: the page hint says the balance is checked daily and that you will get an email before a recharge, but in the current version the check happens at the moment an AI feature is used and no advance email is sent; the Payment method box is informational (the actual charge always goes to the card on file for your account).
