PRISM AAC SUBSCRIPTION Prism AAC is a subscription app: US$4.99 per month, with a 2-week free trial for new subscribers. Subscribe in the app with your Apple Account. Your subscription is linked to a free Synalux account, which you can create in one tap with Sign in with Apple, so the same subscription also works in the web app. Emergency communication, crisis phrases and bedside cards always stay free, with or without a subscription. Your subscription includes communication boards with 22 categories, a keyboard with word prediction, saved phrases, device voices and cached speech, on-device AI, visual schedules and therapeutic games. Each month it also includes 50,000 newly generated natural-voice speech characters and 100 cloud AI requests. Cached playback and device voices never use this allowance.

Payment is charged to your Apple Account when you confirm the purchase, or when the free trial ends. The subscription renews automatically each month unless it is cancelled at least 24 hours before the end of the current period. You can manage or cancel it in your Apple Account settings.
