Sentai is a voice-enabled digital companion for those in need of some extra support in their own home. It offers AI-powered natural conversation, helping adhere to daily routines, track medication, stay well, independent and connected to family and friends.

Digital care combines smart technology and digital assistance to help people live independently, stay well, and feel supported—whether they have care in place or not.

Sentai is a voice-enabled digital companion that provides daily check-ins, wellbeing support, and real-time updates through a connected app. It keeps individuals safe, families reassured, and care providers informed—so everyone stays connected and supported, every day.

Sentai is purpose-built for care, customised to you, and connects you to your friends, family and carers. Unlike Alexa, Sentai has natural conversations rather than command-based interactions, understands ambiguity, and includes features specifically designed for care and wellbeing monitoring.

Sentai is not an emergency call alarm and is not intended to replace call alarms where they serve the purpose to the user. Sentai can be used either on its own as a voice enabled digital companion or in conjunction with an existing emergency call alarm.

We put users at the heart of our product development process. We continually enhance our product based on user and customer feedback, and as new technology that becomes available. We grow our product functionality around our customers’ needs, with the goal to give users more meaningful, personalised and fun experiences every time they interact with Sentai, and care providers and families deeper insight that helps improve the care recipient’s wellbeing and the efficient delivery of care.

No, Sentai only activates when you say "Hi Sentai." It doesn't record or listen to your conversations when not activated. Your privacy is important to us.

It only takes minutes to set up using the app or speaking directly to Sentai to connect to Wi-Fi, or mobile internet through an inbuilt SIM card.

Setting up Sentai is simple. Just plug the device into a power outlet, download the app, and follow the guided setup process to connect to your Wi-Fi. The entire process takes just a few minutes, and our support team is available if you need any assistance.

No problem! The mobile internet enabled version* of Sentai is designed for users who do not have access to Wi-Fi or their own internet connection at home. Whilst the device still needs to be plugged into a power outlet to function, it comes equipped with its own built-in 4G modem. This allows Sentai to connect to the internet via the 4G mobile network without needing a separate Wi-Fi or broadband connection. It's an ideal option for users who want the full functionality of Sentai but don’t have internet at home. *Estimated availability Q2 2025

The 4G Connected Version is designed for users who do not have access to Wi-Fi. While the device still needs to be plugged into a power outlet, it comes with a built-in 4G modem to connect directly to the internet via the mobile network.

Not at all. Sentai was designed specifically to be accessible to everyone, regardless of technical ability. There are no complicated instructions or commands to learn - just talk naturally.

No. Sentai includes a single smart speaker containing all it needs in one solution, minimising the need for users to learn anything new. The use of voice activation technology eliminates the requirement for extensive learning, ensuring a user-friendly experience.

Virtually nothing. Sentai works through natural conversation - users just need to say "Hey Sentai" followed by whatever they want to say. There are no commands to memorize or buttons to press.

Sentai uses AI to act as an intelligent conversational companion that learns from users over time. AI is used to synthesize speech, convert speech to text and text to speech, create conversational content, and intelligently interpret conversations for outcomes and mood. Sentai intelligently adapts to users’ preferences over time, and uses AI to recognise user preferences, needs and behaviours. We use multiple services to deliver a best-in-class experience, for example Microsoft Azure for Speech-to-Text, and Open AI for content creation and analysis. Sentai is designed to be flexible, provider-agnostic and future-proof. We are continuously evaluating new technologies to enhance its capabilities.

Family members can send messages directly to your Sentai speaker through the app. You'll hear the message spoken aloud and can reply simply by talking back. No need to use a phone or computer.

Sentai has a built-in movement sensor that can detect if you haven't been active for an unusual amount of time. If this happens, family members will receive a notification through the app so they can check on you.

Privacy is a priority for Sentai. We use personal data within the system to improve our service offering, never sell data to third parties, and only share data with authorised individuals or organisations.

Yes! Sentai is a learning device and, as such, uses personal data to improve.

Sentai was created specifically for people who may not be comfortable with technology. There's nothing to learn and no complicated interfaces - they simply talk naturally as they would to a friend.

Absolutely not. Sentai is designed to complement and enhance your relationship with your loved one, not replace it. Many families find that Sentai actually improves their in-person visits because they're less focused on checking up and can spend more quality time together.

No. Sentai's solutions look to enhance the care offering by making more hours available through digital care check-ins or by complementing and enriching the in-person care service if this is already in place.

Sentai is a voice-enabled companion that provides daily check-ins, wellbeing support, and real-time updates through a connected app. It keeps individuals safe, families reassured, and care providers informed—so everyone stays connected and supported, every day.

Formal care settings often face workforce shortages, funding gaps, and rising costs. Sentai offers an alternative by using AI and motion sensors to provide caregivers with relevant information about the user's daily routines, activities, and wellbeing.

Businesses can integrate Sentai's technology into their existing services, incorporating it into care plans, enhancing home care services, or offering it as an add-on to their current offerings.

Businesses and organisations, such as domiciliary care providers and local council health authorities, can benefit from partnering with Sentai by offering innovative solutions to their clients or community. Sentai's technology can improve the quality of care, enhance the wellbeing of individuals in need of support, reduce the burden on informal carers, and contribute to cost savings in the long run.
