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.
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.
