# Pay-as-you-go credits Each plan includes a monthly amount of AI usage. If you need more, **Plus** and **Pro** users can buy **pay-as-you-go credits** to keep going past the monthly balance.  ## How credits work - Buy a pack of **$5**, **$10**, or **$20** from **Settings, Account**. - Credits **never expire**. - They are spent **only after** your monthly balance runs out, and **only when** the toggle below is on. ## The "use credits after my monthly limit" toggle This switch is **off by default**. While it is off, when your monthly balance runs out the assistant pauses and your credits are saved for later, so you are never charged by surprise. Turn it on to let the assistant keep working on your credits once the monthly balance is gone. ## Buying Credits are purchased securely on [snoutdata.com](https://snoutdata.com). They are tied to your account and available the next time the app refreshes your plan. See [Plans and billing](https://docs.snoutdata.com/account/plans).
