KotobaiaHow can we help?
Start here for account, purchase and app questions.
Accounts & sign-in
Use the same Kotobaia account across your devices. If Google or Apple sign-in opens an unexpected account, cancel and choose the account you previously used. To delete your Kotobaia account, open the account page in the app.
Purchases & restoration
Sign in to the Kotobaia account used for the purchase, open Membership and choose Restore Purchases. Manage or cancel auto-renewal in the Subscriptions settings of your Apple account. Deleting Kotobaia does not cancel a subscription.
Cloud features & allowances
Available AI, speech and interpretation features depend on your selected mode, device support and membership allowances. The app displays the applicable plan and remaining usage. If a purchase does not appear, restore it while signed in to the original account.
Contact Sunimori
Include your app version, device model and a description of the issue. Do not send passwords, API keys, payment card information or private recordings.
