A friendly companion that respects your privacy and supports what you love
Sentai is a voice-enabled digital companion that provides daily check-ins, wellbeing support, and real-time updates through a connected app. It keeps those in need of support safe, their families reassured, and care providers informed—so everyone stays connected and supported, every day.


Natural conversation
Sentai works through its own smart speaker that features a precision microphone, and built-in presence sensor, with the option to connect to additional sensors for expanded functionality.
Designed for simplicity, it can be connected in seconds and requires no complicated manuals - just natural, friendly conversation with a companion that's there when you need support. It helps combat loneliness while supporting routine management such as taking medication, handling grocery needs, or flagging prolonged periods of inactivity, ensuring nothing is overlooked.

Insight and visibility
The Sentai app offers peace of mind to families and helps maintain clear visibility into a loved one’s wellbeing through real-time messages and alerts.
Sentai’s AI-powered analytics identify when help is needed, highlight emerging problems and provide insight into daily activities.

Family connection
Beyond monitoring, Sentai brings together friends and family into a connected support circle. This collaborative approach lightens the load for individual family members by sharing responsibilities.
Instant notifications keep everyone informed, and the in-app family chat feature allows users to send messages directly to the speaker, making communication simple and seamless.
