Sentai makes a voice-based AI companion for older people who live independently at home. The device works through natural conversation, offering reminders for meals, medication and appointments, keeping shopping lists and passing messages to relatives, with no screens or wearables involved. A companion app gives families and carers a summary of daily routines, a wellbeing score and alerts when patterns change, such as skipped meals or quieter weeks. The London-based company sells direct to families on a monthly subscription and also works with care organisations and research partners.
