## In brief

Free covers basic corrections. Pro and Business expand AI features and team controls. Limits are in the pricing table.


## Limits
The Pro price is shown regionally. In Germany the plans page shows Pro at €12; the plan data on the same page lists Pro at €144 per year, €60 per quarter, and €30 billed monthly. The headline figure therefore matches annual billing. A USD list price could not be determined from Germany; the previously noted $12 and £10 come from other regions. FAQ: switching from Premium to Pro cancels Premium with a prorated refund. Payments: card or PayPal; invoice from 10 members on an annual plan.
