# Plans, credits, and billing

> Compare DiagramAI plans and understand AI credits, subscriptions, seats, and refunds.

DiagramAI uses file limits for stored diagrams and credits for successful AI generation or editing.

## Plans

| Plan     |              Price |                      Included credits | File limit | Team access                 |

Business includes 3 seats. Each additional seat costs \$12 USD per month and adds 60 shared credits per billing period. Seat increases can include a prorated charge and prorated credits for the remaining period. Seat decreases take effect on the next billing date.

## How credits work

* Successful AI creation and editing requests consume credits based on actual token usage.
* Failed AI requests do not consume credits.
* Personal workspaces use the account's personal balance.
* Team workspaces use the organization's shared balance.
* The usage page shows the available balance and recent activity.

DiagramAI checks the estimated requirement before sending an AI request. A request can also stop without changing the canvas if the final charge would exceed the available balance.

## Credit packages

A credit package costs \$12 USD and adds 60 credits.

* It is a one-time purchase, not a subscription.
* It can be purchased for Free, Pro, or Business usage.
* Package credits expire 365 days after purchase.
* A completely unused package can be eligible for a refund requested within 30 days.
* Once any credits from the package are used, the package is generally non-refundable unless the law requires otherwise.

For Business, choose the organization as the purchase destination when you want the credits added to its shared balance.

## Subscriptions

Pro and Business subscriptions renew monthly until canceled. Use **Manage subscription** on the usage and billing page to open the customer portal.

After cancellation:

* Future renewal stops.
* Paid access normally remains available until the end of the current billing period.
* Unused time is not prorated or refunded unless required by law or covered by the Terms of Service.
