Why don’t I get billed for the Advanced AI Assistant or Translation add-ons flat fees immediately?

We bill for these add-ons at the end of the billing period so we can include any usage charges alongside the flat fees.

These add-ons will not appear on your bill until they are used for the first time.

The flat fees for these two add-ons include a limited number of actions:

• Advanced AI Assistant add-on: includes a monthly limit of successfully answered questions. If you go over that limit, GitBook continues answering questions, and we bill each additional successfully answered question as usage on your next invoice.

• Translations add-on: includes a set number of translated words per month, with an additional charge per 1000 translated words beyond that limit.

What happens if my question limit goes over?

If you go over the monthly limit included with the Advanced AI Assistant add-on, GitBook continues answering questions.

We bill the extra successfully answered questions as overage usage at the end of the billing period.

See our pricing page for specific limits and pricing for each add-on.
