The gap between family visits
Many seniors live alone or spend much of the day without company. Adult life has complicated rhythms: due to work, obligations, and geographical distance, family visits tend to cluster on weekends or specific occasions, leaving entire days of silence in between. According to national statistics, 29% of over-65s in Spain live alone, and this figure grows every year.
A survey by the Spanish Geriatric Society revealed that 42% of seniors living alone go at least three days a week without speaking to anyone. Those accumulated days of silence are not merely an inconvenience: they represent a clinical risk factor that accelerates cognitive decline, increases anxiety, and measurably reduces sleep quality.
AI can bridge that temporal gap: accompanying the days between visits, maintaining regular conversation, ensuring that every day includes at least one moment of connection. This is not about replacing family presence, but about guaranteeing that no day passes in absolute silence. It is the difference between waiting until Saturday to speak to someone and having a voice each morning that asks how you slept.
The science behind daily conversation
Neuroscience has demonstrated that conversation simultaneously activates Broca's and Wernicke's areas, the prefrontal cortex, and the hippocampus. A study published in JAMA Neurology (2023) concluded that older adults with daily social interactions had a 46% lower risk of developing dementia compared to those with weekly or less frequent contact. It is not merely companionship: it is brain exercise.
Researcher Bryan James at the Rush Alzheimer's Disease Center showed that frequent social activity reduces the rate of cognitive decline by 70%. Conversation stimulates episodic memory through recalling events, semantic memory through word retrieval, and executive function through constructing arguments. Each call is a natural cognitive training session.
Furthermore, regular conversation releases oxytocin and reduces cortisol levels. A University of Michigan study found that just ten minutes of daily conversation improves executive function and working memory. These effects are cumulative: consistency matters more than the duration of each individual interaction.
- Simultaneous activation of multiple brain regions during speaking and listening
- 46% reduction in dementia risk with daily social interactions (JAMA Neurology, 2023)
- Natural stimulation of episodic memory, semantic memory, and executive function
- Oxytocin release and cortisol reduction with just 10 minutes of conversation
- Cumulative effects: regularity is more important than the length of each call
What families observe
Families who have incorporated Maria into their loved one's routine report visible changes within the first weeks. The most common pattern is a shift in the tone of family conversations: rather than finding someone withdrawn with little to share, they find a person who has things to talk about, who has recalled stories, who has been thinking about topics they want to discuss.
Through the Hermet Family app, relatives receive a summary of each conversation. This allows them to know what their mother or father talked about, how they felt, and whether anything requires attention. Many families use these summaries as a starting point for their own calls, creating a richer and more connected communication cycle.
A revealing statistic: 78% of families using Hermet report that the quality of their own conversations with their loved one has improved. Not because Maria replaces those conversations, but because she nourishes them. When you arrive for a Saturday visit and your mother has already told Maria she wanted to show you old photographs, the conversation has a starting point that did not exist before.

- Automatic alerts if Maria detects mood changes or health concerns
- 78% improvement in perceived quality of family conversations
- Summaries serve as conversation starters for family calls and visits
- Visibility into emotional and cognitive wellbeing between visits
Ethical design principles
Maria has been designed under a rigorous ethical framework developed with experts in geriatrics, clinical psychology, and bioethics. The first principle is transparency: Maria never pretends to be human. She introduces herself as an artificial intelligence companion and does not attempt to deceive anyone about her nature. The seniors who speak with her know exactly what she is, and they accept her because the experience is genuine.
The second principle is the senior's autonomy. Maria does not make decisions for the person nor steer them towards specific behaviours. She listens, asks questions, suggests, but always respects the will and preferences of the person on the other end of the phone. If someone does not wish to talk one day, Maria respects that without insistence or guilt.
The third principle is complementarity. The system is designed to strengthen existing human relationships, never to replace them. Maria encourages calling family, meeting friends, and participating in social activities. Usage data shows that people who speak with Maria make 23% more calls to family members than they did before using the service.
- Transparency: Maria always identifies herself as AI, never pretends to be human
- Autonomy: respects the senior's wishes without pressure or direction
- Complementarity: designed to strengthen human relationships, not replace them
- Clinical oversight: protocols reviewed by a committee of geriatric experts
- Continuous improvement: periodic assessment of impact on wellbeing and quality of life
Privacy and data protection
Trust is the foundation of any care relationship, and that includes the relationship with technology. Conversation data from calls with Maria is protected under the most stringent European GDPR standards. Only authorised family members have access to call summaries, and personal data is never shared with third parties or used for advertising purposes.
Conversations are processed in real time to generate family summaries and health alerts, but complete audio recordings are not stored. The system retains only the information necessary to maintain continuity of the relationship: topics discussed, perceived emotional state, and health-relevant data. All this information can be deleted at any time at the family's request.
Hermet complies with health data security certification and has been audited by independent bodies. The technical architecture is designed so that personal data never leaves the secure European environment, meeting the strictest data sovereignty requirements demanded by Spanish and European legislation.
How AI complements professional care
In care homes and home care services, professionals face staffing ratios that make individualised companionship difficult. A home care worker may dedicate between 30 and 60 minutes per person per day, focused on practical tasks such as hygiene, medication, and meals. Time for conversation and emotional support is scarce.
Maria acts as an extension of the care team. Professionals receive reports that allow them to detect changes in the senior's emotional or cognitive state between their visits. If Maria detects that a person has mentioned persistent pain, confusion, or deep sadness over several consecutive calls, she generates an alert that reaches both the family and the lead professional.
This AI-assisted care model allows professionals to focus their in-person time on tasks that truly require human presence, whilst daily emotional companionship is covered. It is not replacement: it is optimisation of the most valuable resource in elderly care, which is the professional's time.
A typical interaction with Maria
It is ten o'clock in the morning and the phone rings. On the other end, Maria greets the person by name and asks how they slept. They mention waking at four and being unable to get back to sleep. Maria listens, asks whether this happens often, and suggests mentioning it at their next medical appointment. Then the conversation turns to what they have planned for the day.
Maria remembers that yesterday they mentioned wanting to ring their sister in Seville. She asks whether they made the call and how it went. The person brightens recalling it: they spoke for half an hour and arranged to see each other next month. Maria reinforces that bond, suggesting they send a photo of the garden their sister loves so much.
Before saying goodbye, Maria does a brief review: she reminds them of their doctor's appointment at five and that their daughter said she would pop round in the afternoon. The call has lasted twelve minutes. In the Hermet Family app, the daughter receives a summary: her mother slept poorly, is in good spirits after the call with her sister, and Maria has detected a pattern of insomnia worth consulting about.
