COMPANION & LONG HORIZON AI
Know whether an AI relationship is helping or harming users — over time.

Derived from language. Independent of engagement metrics.
Products built for ongoing relationships need to know whether those relationships are beneficial. Receptiviti measures the psychological trajectory of the relationship — session by session, across time — from the language itself.

THE CORE TENSION
Engagement and wellbeing are not the same signal.
Engagement metrics — session length, return rate, messages sent — tell you whether users keep coming back. They do not tell you whether coming back is good for them. These signals can move in opposite directions, and without measurement, you cannot know which way they are going.
A strong, trusting relationship between a patient and human provider — the therapeutic alliance — is one of the most reliable predictors of successful treatment outcomes. Relationships with AI systems are one-sided, even if the user perceives otherwise.

WHAT RECEPTIVITI MEASURES
The signals that determine whether an AI relationship is beneficial over time.
Scored from language — session by session and longitudinally — giving you a structured, auditable view of how the relationship is actually evolving.
WELLBEING TRAJECTORY
Is the user better or worse over time?
Emotions, distress signals, anxiety, cognitive load, and negative affect tracked longitudinally across sessions. Identifies whether psychological state is improving, stable, or declining — the signal engagement metrics cannot provide.
DEPENDENCY & ATTACHMENT
When does engagement become over-reliance?
Dependency appears in language before behavior. As cognition is outsourced to AI, confidence and analytical thinking decline while inward focus rises. These shifts precede entrenched dependency.
THERAPEUTIC ALLIANCE
Is the relationship genuinely supportive?
In validated research, the implicit coordination of function words between two parties predicts therapeutic alliance, relationship stability, and rupture in psychotherapy research better than self-report.
DISTRESS ESCALATION & CRISIS
Early warning, grounded in clinical science.
Psycholinguistic distress signals validated in peer-reviewed research as predictors of crisis trajectories weeks in advance. Not heuristic triggers — measured signals with a published scientific basis.
Receptiviti measures psychological signals from language. It does not diagnose, classify individuals, or replace clinical judgment. Scores are structured variables for research and evaluation purposes.
INTEGRATION
Into your session layer, safety infrastructure, and product analytics.
Pass conversation text to the API. Receive structured psychological variables. Append to your existing session logs. No changes to your data infrastructure.
REAL-TIME SCORING
Score each conversation turn as it happens. Distress and escalation signals available within 65ms — fast enough to inform in-session response logic or trigger safety protocols.
LONGITUDINAL MEASUREMENT
Session-level and cross-session measurement of wellbeing trajectory and therapeutic alliance, patterns that only become visible over time — not in a single conversation
SAFETY TEAM ACCESS
Structured psychological variables accessible to clinical, safety, and product teams — not just raw conversation logs. Scored, documented, and auditable evidence of how the relationship is evolving
ON-PREM DEPLOYMENT
For products with sensitive user data, Receptiviti is available as a containerized on-prem deployment. Conversation text never leaves your infrastructure.
ACTIVE RESEARCH
We publish. We contribute.
Receptiviti's team and academic advisors publish peer-reviewed research on the psychological dimensions of language and human behavior. Receptiviti also conducts its own research and experiments, contributing to the questions AI safety and companion AI teams are actively working on.
