What Amigo does
Palliative management through conversation and daily action.
Amigo is an AI phone companion for the palliative management of cognitive impairment. It combines regular cognitive and social stimulation with personalized, peer-reviewed lifestyle guidance to improve symptoms and reduce modifiable risks—while tracking changes in condition, autonomy and safety.

Every call follows the same support loop.
Amigo uses repeated conversations to understand the senior, adapt its support and follow change over time.
01
Assess & learn
Build a personal baseline and learn the senior’s life, abilities, routines and support network.
02
Converse & stimulate
Use friendly, reminiscence-informed conversation for regular cognitive and social stimulation.
03
Coach
Turn peer-reviewed lifestyle guidance into realistic actions for that senior.
04
Track & signal
Measure change against the personal baseline and alert authorized caregivers when needed.
Hyper-personalized lifestyle support
Recommendations built for what the senior can actually do.
Movement, nutrition, hydration, sleep and social suggestions are adapted to the senior’s mobility, autonomy, routines, preferences and available support.

What happens on the phone
Friendly check-ins, meaningful conversation and practical coaching.
The senior can receive scheduled check-ins or call Amigo at any time, using a regular phone. No app, screen or new device is required.
Cognitive & social stimulation
Friendly conversations informed by reminiscence therapy.
Amigo uses known people, places, music and life events to create enjoyable reminiscence conversations—not tests or questionnaires.
Personalized lifestyle coaching
Peer-reviewed guidance converted into practical daily actions.
Movement, nutrition, hydration, sleep and social actions are selected for symptom and risk management, then adapted to the senior’s reality.
Clinical signal layer
Clinical signal extraction from everyday conversation.
A separate analysis layer converts acoustic, linguistic and conversational markers from repeated calls into longitudinal cognitive, mood and safety signals.

Module 01
Cognitive Tracker
A multimodal conversational analysis module combining acoustic, linguistic and behavioral features with context-aware qualitative scoring. Only the senior’s turns contribute to the measurement layer.
Measurement layer
Lexical diversity (TTR)
Mean utterance length
Repeated bigram rate
Words per minute
Pause timing & speech rhythm
Prosodic variability
Participation ratio
Coherence, idea density & word finding
Output
Per-call cognitive snapshot, domain scores and longitudinal index
Module 02
Mood Signal
A structured affective-analysis module that combines semantic content with paralinguistic cues to model the dominant emotional state and seven clinically relevant dimensions on a 0–10 concern scale, with evidence retained for review.
Measurement layer
Mood & affect
Anhedonia & apathy
Anxiety
Hopelessness & futurity
Social connection
Self-worth
Somatic burden
Output
Daily mood profile, dimension trends and change from prior period
Module 03
Alert & Escalation Module
A deterministic decision layer that maps structured dimensions and critical flags to severity and follow-up pathways. It separates the senior’s own symptoms from reactions caused by an AI error.
Measurement layer
Emotional risk
Cognitive disorientation
Physical distress
Safety concern flags
Acute distress flags
Low / Medium / High / Critical rules
Output
Prioritized emotional, cognitive or physical follow-up
Longitudinal methodology
A within-person longitudinal model.
The first ten qualified cognitive snapshots establish a frozen individual reference distribution. Each later measure is transformed into a direction-aware, weighted z-score. The composite is mapped to a 0–1000 index where 500 is the senior’s own baseline; a 14-day rolling regression estimates the direction and rate of change.

These modules generate observational support signals. They do not diagnose cognitive impairment, determine treatment, or replace clinical assessment.
Two ways to reach Amigo
Scheduled check-ins—and support whenever it is needed.
The same Amigo is available for routine follow-up and for unplanned moments when the senior wants to talk or needs help deciding what to do next.
Scheduled callAmigo checks in proactively
Amigo calls to discuss mood, sleep, physical state, plans and immediate needs, then provides conversation or coaching.
Available 24/7The senior can call Amigo
When the senior feels lonely, confused or needs practical support, Amigo provides an immediate first conversational response—without every call falling first to family or caregivers.
After each callAmigo decides what happens next
The call updates the longitudinal profile. Amigo can resolve a simple need conversationally or escalate a meaningful condition, autonomy or safety concern.
What caregivers receive
Follow the condition, autonomy and risks between visits.
Calls update cognitive trajectory, mood and autonomy trends, and prioritized safety alerts—giving caregivers visibility between visits.
Cognitive trajectory
Track changes in conversational coherence, recall, fluency and engagement relative to a personal baseline.
Mood & autonomy
See changes in affect, participation, routine and the senior’s reported ability to manage daily life.
Safety signals
Surface repeated confusion, acute distress, unmet needs and stated safety concerns according to configured escalation rules.
24/7 first response
Immediate support without placing every first call on family.
Seniors can call their Amigo whenever they need conversation, reassurance or practical guidance. Amigo handles appropriate first-line support, documents the interaction and involves family or caregivers when the situation requires human follow-up.
Always available for non-emergency conversation and guidance
Immediate response to loneliness, uncertainty or routine needs
Configured escalation to authorized family or caregivers
Does not replace clinicians or emergency services
Questions families and care teams ask.
Can the senior call Amigo at any time?+
Yes. In addition to scheduled check-ins, the senior can call their Amigo 24/7 from a regular phone for conversation, reassurance or practical guidance. Amigo can provide an immediate first response and involve an authorized person when follow-up is needed.
Does Amigo cure or diagnose dementia?+
No. Amigo is designed for the palliative management of cognitive impairment: improving symptoms, reducing modifiable risks and following change over time. It does not claim to cure dementia or replace a clinician’s diagnosis.
What does “palliative management” mean here?+
It means actively managing symptoms, daily function and risks while a person lives with cognitive impairment. Amigo does this through cognitive and social stimulation, personalized lifestyle coaching and longitudinal monitoring. It does not mean end-of-life care.
How does Amigo provide cognitive and social stimulation?+
Amigo calls the senior for regular friendly conversations and applies reminiscence-therapy principles to discuss meaningful people, places, music, routines and life events using the personal context it has learned.
What does the senior need to use it?+
Only a regular phone. Amigo calls at an agreed time; the senior answers and talks. No app, screen, wearable or new device is required.
One companion for scheduled care and 24/7 support.
