Sayella

Sayella とは？

Sayella gives nonverbal children and adults a voice: tap symbols, build sentences, and the device speaks. A complete research-based core-word board works from the first tap. Free to start, and the talking part stays free forever, offline. No lapsed subscription can ever switch off a voice. Premium adds cloud sync, five child profiles, therapist team access and AI symbol generation, up to a one-off lifetime licence. Incumbents charge many times more. iPhone and iPad today, web and Android next.
