Use Billing to see the current organization plan, manage subscription changes,
and track AI credits.

Only organization owners can manage billing or buy credits.

## Plans

Radiant plans control which product capabilities are available to an
organization.

| Plan | Includes                                                                                                                             |
| ---- | ------------------------------------------------------------------------------------------------------------------------------------ |
| Free | API reference generation, API playground, no-code editor, CLI, custom domain, and up to 5 builds per day                         |
| Pro  | Everything in Free, plus team members, Knowledge Assistant, writing agent, up to 5 docs sites, unlimited builds, and 500 AI credits a month |

The Billing page shows the current prices, current plan, renewal information,
and any scheduled plan changes.

<Callout type="info" title="Build usage is organization-wide">
  The Free build allowance is shared by every docs site in the organization. Pro
  includes unlimited builds for normal product use, with automatic
  abuse-prevention controls for unusually high activity.
</Callout>

Each site build counts separately. For example, if one monorepo push changes
three connected docs roots, Radiant starts and records three organization
builds.

## Manage billing

Owners can use Billing to upgrade, manage, or change the organization plan.

If the organization has an active Stripe customer, Billing opens the billing
portal for subscription management. If not, Radiant starts checkout for the
selected plan.

## AI credits

Pro organizations receive **500 AI credits** every billing period for the
Knowledge Assistant and the writing agent. Included credits reset each period.

Credits are metered on what each action actually costs to run, so cheaper
models use fewer credits. The model pickers show a typical cost range for each
model, for example `~0.5–1 credits per question` for the Knowledge Assistant or
`~1–4 credits per run` for the writing agent. A credit is worth roughly one
cent of AI work.

The Usage page shows:

- How much of the included credit allowance has been used this period.
- Purchased credits used this period.
- Remaining purchased credit balance.
- Credits used per feature and per day.

## Buying credits

Buying credits is available on Pro. Purchased credits never expire and are
used after included credits run out.

Owners can buy credits from Billing. Credits are priced at 100 credits per
dollar.

| Limit            | Value                 |
| ---------------- | --------------------- |
| Minimum purchase | 500 credits ($5)      |
| Maximum purchase | 50,000 credits ($500) |

## Out of credits

If an organization runs out of credits, AI-powered actions may be blocked
until included credits reset or more credits are purchased.

For the Knowledge Assistant, this can affect reader questions and context
processing. For context sources, it can affect web page refreshes and custom
note processing.

## Common questions

<AccordionGroup>
  <Accordion title="Who can manage billing?">
    Only organization owners can manage billing, change plans, or buy credits.
  </Accordion>

<Accordion title="What are included credits?">
  Included credits are the 500 AI credits Pro grants each billing period.

</Accordion>

<Accordion title="Do purchased credits expire?">
  No. Purchased credits carry over month to month and are used after included
  credits run out.
</Accordion>

<Accordion title="How many credits does an action use?">
  It depends on the model and the size of the task. Each model picker shows a
  typical cost, and the Usage page shows exactly what was used.

  No. Build activity is tracked across the organization. The Free daily
  allowance is shared by every connected docs site, while Pro includes unlimited
  builds for normal product use.
</Accordion>

  <Accordion title="Why is an AI action blocked?">
    The organization may not have the required plan, or it may be out of
