One-time purchase, restore in the app
Regional pricing is shown in the app before payment confirmation. Pro is not an auto-renewing subscription. Replaying generated audio does not spend additional quota. The 3,000-character allowance applies to new audio from the six advanced voices, not the two free voices; it resets by the device’s local day.
No quota does not remove device limits
Both versions use the same engine. Speed depends on device, temperature and content. Books are split into audio parts and still need memory and storage. Pro does not enable TTS on this website.
