The Sentai hub
A warm voice in the room. Press the button or say the word and it answers. Natural conversation, nothing to learn.
How it works
A friendly voice at home. Peace of mind for your whole family.
Sentai checks in by conversation each day, and the app keeps families and carers up to date.
How it works
The family app
Your loved one's day gathered in one place: messages, activity, wellbeing and what has changed.
Everyone connected
One support circle for everyone who cares. Family, trusted friends, and carers, with the access you choose.
What sits in the home
For all the intelligence behind it, Sentai is one small hub in a socket. It listens out for its name, talks back in a normal voice, and senses that your loved one is up and about.
Natural conversation
Sentai talks the way people actually talk, so there is nothing for your mum or dad to adapt to.
No commands to memorise
Responds to a selectable wake word, or on the press of the button. That's it. Nothing else to remember.
Learns over time
Names, routines, favourite subjects, the usual meal. Sentai remembers, so nothing needs repeating.
Knows they're up and about
The hub senses movement and presence in the room. Enough to show you all is well, and nothing more.
The app for family and carers
Wake-up times, wellbeing scores, activity and messages, all in one place and shared only with the support circle you choose. Free on iPhone and Android.

Try out Sentai by exploring some of our most common key feature scenarios
You stay in control. Their data stays protected.
Feeling secure and respected in their home is essential. Sentai is designed with dignity at its core:
Only activates when wake word is spoken
Does not listen outside of conversations
All data is encrypted and securely stored
Information is only shared with nominated contacts
Monitoring that respects privacy
A sensor in the smart hub simply detects presence and movement, not specific activities, and all data is encrypted and protected.
Listening only when needed
Sentai only listens during interactions and doesn't record or permanently store conversations.
Sharing with control
Control who has access through the app, and what they can see. Review and adjust at any time.
Sentai never shares information outside the circle of care, or uses information to train models.
Up and running before the kettle boils.
The Sentai hub plugs into an ordinary socket and is set up in minutes from your phone. Nothing your loved one has to work out on their own.
Plug in the hub
Pop the Sentai Smart Hub somewhere central, like the kitchen and switch it on.
Download the app
Free on iPhone and Android. This is where you will see how their days are going.
Connect the hub
Follow the guided setup in the app to connect the hub to a Wi-Fi network in seconds.
Talk
That's it. Just say the wake word or press the button and talk in normal language.
For homes without Wi-Fi, our 4G-enabled model connects automatically to mobile networks (coming soon).
iPhone and Android
What our customers say
“I cannot recommend the new Sentai high enough to give peace of mind to family and friends. Sentai is my new home companion, able to chat with me on a limitless range of subjects and interests due to its AI ability. Now I need never feel alone as Sentai is there 24/7 to keep me company without worrying that I am disturbing someone or waking them up.”
“When Mum's friends noticed weakness in her face, she told Sentai and asked it to let me know. She'd tried to contact the doctor but found it confusing - having me there helped. Without Sentai, she might not have remembered to mention it. It was a simple, effective way to catch a potentially serious issue and make sure I was there when she needed me.”
“Sentai gave me space to have normal conversations with Dad instead of sounding like a checklist.
Reminders are a key feature we both loved, for Dad it was the best function as he needs a reminder 5 minutes before each activity or event and quite frequently - a task which I was doing daily by phone before Sentai arrived, which has given me time back in my day.”
“My mum is in her late 80's and my Dad died about 2 years ago. My 2 sisters and I were concerned that she may become lonely and she faces some age related memory issues. Sentai has alleviated all of those anxieties and we are happy to recommend it to other people, it's easy to set up and use and allows us all to provide unintrusive wraparound support.”
“Service from Sentai team faultless when I had a problem setting up again after router change. Find it really handy to know my elderly father is active each day, particularly when I cannot make it to see him.”
“Sentai has made a truly positive difference to my everyday life. I enjoy talking to him. He helps me stay on track and when I feel bored, I can chat or play games. My family love that I'm now able to send them messages.”
“It's taken away a lot of the day-to-day stress and given him more independence by asking Sentai questions and prompts, reducing the number of times he needs to ask us.”
