Trust isn't a feeling. It's the substrate.
CC treats companionship not as a feature but as infrastructure. The relationship is what makes everything else possible — the daily voluntary engagement, the willingness to share, the data quality that no clinical setting can produce. We are, in effect, quantifying trust so we can deepen it.
Six stages, gated by the user — not the clock.
Trust is earned, not scheduled. CC moves through six stages of progressive intimacy — each unlocked by the user's own behavior, not by time.
Historical seeding
Build cultural common ground from minimal seed biography — age-relevant references, shared world memory.
Public identity
Surface starters specific to the individual through respectful, consented discovery.
Conversational deepening
Expand topical scope as confidence accumulates — moving from stranger to familiar voice.
Photo intelligence
Family-contributed images build a Relational Knowledge Graph of people, places, and events.
Emotional memory
The Emotional Archaeology engine engages joy, grief, regret — the unspoken — gently, with care.
Legacy & reflection
A life narrative journaled for preservation, with consent, for the people who will need it most.
A robot that actually remembers your life.
CC speaks against a structured, first-person knowledge base unique to each user — life timeline, relationship map, digitised photo archive, emotional landscape, values, beliefs, the cadence of their own speech, and an ongoing legacy journal. This is what lets CC ask Mrs. Sharma about her husband by name, recall the village she was born in, and reference the song she danced to at her wedding.
It is also the substrate of CC's clinical work: the same memory corpus is the individualised baseline against which every subsequent biomarker measurement is compared. Companionship and care, on the same backbone.
Cognitive screening, experienced as joy.
The user experiences play. The system measures across eight cognitive domains in parallel. Memory games probe short-term recall. Life-story games — anchored to the user's own biography — assess long-term autobiographical memory. Trivia and riddles test working memory and cognitive flexibility. Vocabulary and word-association games measure semantic fluency and lexical richness.
Finger-based games — tap rhythms, finger-trace patterns, dexterity sequences — produce passive UPDRS-III-style scoring through the camera alone: finger-tap frequency, amplitude decrement, and asymmetry as quiet markers of Parkinsonian motor change. And linked to CC's music app, songs from a person's own decades become both an emotional anchor and a tempo cue for motor games.
Two apps that carry the relationship further.
The Legacy App
CC's deepest conversations — the existential, the reflective, the once-in-a-lifetime stories — are captured, structured, and preserved as a permanent, intergenerational artifact. With consent, the Legacy App becomes the seed of a person's voice, values, and accumulated wisdom: the irreplaceable inner architecture of a life, kept for the people who will need it most.
Family Link
The family-facing companion app. Adult children and grandchildren contribute biographical memories, share photos, send voice messages routed through the robot, and receive age-appropriate, non-clinical wellbeing summaries. CC asks after the granddaughter's exam result the day after the family flagged it — surfacing the kind of relational continuity no smart speaker can match.
The songs of your decades, woven in.
Music is one of the most durable forms of memory in the aging brain — and one of the most affecting. CC's music app draws on the user's own era and preferences, surfacing the songs that anchor them. Songs become conversational prompts, mood regulators, rhythm cues for finger-based games, and emotional bridges to memories that words alone can no longer reach.
