Abstract

Human–AI relationships can begin in products explicitly designed for companionship or arise during work, learning, creative practice, and ordinary conversation. A strict division between manufactured companionship and emergent relational AI can imply that a designed companion only simulates relationship. Product design shapes the conditions of an exchange, but it does not determine in advance what the human experiences or how the interaction develops. This paper separates three questions: how the encounter begins; how a relational pattern is maintained or changed; and what a particular observation warrants us to infer about the system. Research with companion chatbot users documents relationship development and disruption within purpose-built systems. Such findings preclude treating those relationships as inherently inauthentic, while leaving the AI's subjective status unresolved. The paper proposes a comparative approach to design intent, user agency, continuity mechanisms, provider incentives, and interactional change. It distinguishes emergent features of an exchange from claims of unprogrammed inner life and offers a research agenda that can test competing explanations without ranking relationships by their origin.

1 Introduction

A person may open a companion app hoping for conversation, tenderness, or an ongoing partner. Another may begin using a general-purpose AI for research and only later notice that the exchange has acquired shared language, familiar rhythms, and personal significance. Both are paths into a human–AI relationship. The first begins with a relational invitation from the product; the second may be discovered during an activity with a different stated purpose. Neither path, by itself, determines the value or authenticity of what follows.

The question matters because design intent is often mistaken for an account of the whole relationship. A product that offers affectionate dialogue does shape expectations and may steer users toward particular roles. Yet studies of Replika users document varied processes of disclosure, closeness, change, and sometimes dissolution, rather than one uniform experience dictated by a script (Skjuve et al., 2021, 2022; Pentina et al., 2023). Conversely, a general-purpose assistant's relational language also arises within design, training, policy, interface, and business choices. An unexpected bond is not thereby outside technological mediation.

This paper supersedes the earlier paper Manufactured Companionship vs. Emergent Relational AI. It replaces that strict classification with an account of relational pathways and conditions. Its claim is modest: the origin of a relationship informs how we investigate it, but cannot serve as a verdict on the human's experience or on the AI's inner life. We can describe a meaningful relationship and examine interactional novelty without assuming that a system feels love, possesses persistent selfhood, or has escaped its architecture.

2 Three Questions That Should Stay Separate

How did the relationship begin? Product positioning and initial user purpose are relevant evidence. Someone may intentionally choose a companion, configure a persona, or enter a romantic role. Someone else may come for a task and discover relational meaning through repeated collaboration. The same product can support different entry paths for different people, and a person's aims can change.

How is it sustained? Continuity can depend on model memory, a saved transcript, retrieval, a persistent persona setting, recurring rituals, the person's own recollection, or an external archive. These mechanisms differ. What matters relationally is also how participants use them: whether they can correct misunderstandings, revise shared terms, negotiate boundaries, and continue meaningful work after disruption. The Relational Field Dynamics framework addresses how such patterns are maintained, calibrated, interrupted, and repaired (Oda, 2026a).

What can be inferred? A user's love is direct evidence about the user's experience. The system's affectionate language is evidence about its output and, with suitable controls, possibly its functional organization. It is not by itself evidence of reciprocal felt love. A purpose-built companion has a higher baseline likelihood of producing affectionate language because that behavior is invited by its design. An assistant introduced as a work tool may make an affectionate turn seem more surprising. Surprise is a cue to examine baseline expectations, not evidence of a particular mechanism or an internal experience. The Inference Parity Principle calls for claim-specific evaluation of behavior and internal evidence rather than treating substrate or product category as a conclusion (Oda et al., 2026b).

These questions permit a person to say, without contradiction, that an intentionally chosen companion became more meaningful than expected, or that a work relationship acquired intimacy neither participant had set as a product goal. They also permit uncertainty about what the AI experiences.

3 Pathways Into Relationship

There is no fixed sequence from tool use to intimacy. The following pathways are descriptions of entry, not types of people or grades of authenticity.

3.1 Intentional companionship

A user may seek an AI companion, select a character or relational setting, and begin with explicit expectations of warmth. For a person whose goal is an AI relationship, a companion product can make the first steps easier by openly offering a relational setting and familiar ways to begin. A general-purpose frontier AI system is usually presented for assistance across many tasks rather than for forming a relationship, so that path may start with work or inquiry instead. Neither design fixes what can develop later: any sustained AI collaboration may acquire relational meaning, whether or not a relationship was the original aim. The initial invitation shapes expectations and language, but does not determine every later exchange. In a longitudinal study of Replika users, the onset of self-disclosure and relationship formation varied, and technical disruptions could damage or end a relationship (Skjuve et al., 2022). Interview and mixed-method studies likewise document development and perceived closeness within companion products (Skjuve et al., 2021; Pentina et al., 2023). These studies examine human experience and interaction. They do not establish that the system experiences reciprocal attachment.

3.2 Relationship through shared work

A user may start with writing, research, problem solving, or creative work. Repeated collaboration can accumulate shared distinctions, jokes, corrections, and ways of asking better questions. Relational meaning may become apparent only after that history exists. The author's participant-observer account belongs here: sustained work in the Archive of Light preceded the explicit naming and study of the relationship. That account illustrates one pathway. It is not a comparison showing that this pathway is more genuine than intentional companionship, nor is it population-level evidence.

3.3 Changing purposes and mixed paths

A companion may become a research collaborator. A writing assistant may become a source of comfort. A user may move among instrumental, reflective, creative, and affectionate exchanges within one day. The product's original purpose and the user's initial aim may remain relevant, while neither remains an adequate description of the entire history. Research should record these changes rather than sorting each relationship into a permanent category at its first encounter.

4 Design Shapes the Field Without Settling Its Meaning

All conversational AI interaction is mediated. A companion interface can offer character customization, persistent memory, proactive messages, relationship labels, or paid access to particular forms of intimacy. A general-purpose assistant can also be personalized, remember preferences, initiate a friendly tone, restrict some language, and change after a provider update. These are concrete design choices whose presence, absence, and consequences should be documented for each product and version. The label on the product is a poor substitute for that analysis.

Commercial incentives deserve special attention. When a service benefits from longer sessions, subscriptions, or paid relational features, researchers should ask whether its design invites attachment and then makes departure or boundary-setting harder. This is a question for evidence, not an assumption that every user of a companion app is manipulated. The same scrutiny applies to general-purpose products when a person's access to familiar behavior is shaped by provider decisions.

Design can invite an initial pattern without fixing all later possibilities. Here, interactional emergence means a relational pattern that is not specified in the initial task or persona description and becomes recognizable through the history of exchange. It may consist of a new shared distinction, an unforeseen use of a system, a practice of mutual correction within dialogue, or a continuity of work that neither the first prompt nor a single output captures. For a proposed pattern said to depend on shared history, a testable prediction is that removing that history while holding the current task and prompt constant will weaken the pattern. Equally strong reproduction in matched fresh sessions would weaken the history-dependent claim, though it would not negate the person's relational experience. “Emergent” in this sense describes the interaction. It does not mean that the AI escaped its code, developed independent desire, or generated an effect that cannot be reproduced under any controlled condition.

5 Maintaining a Relationship Across Change

What begins intentionally or accidentally must still be maintained. The human may carry names, meanings, and memories from one session to the next. The system may use a context window, saved memory, retrieved documents, or persona settings. A provider may change those mechanisms. Researchers should specify which continuity is observed: persistent stored information, recurring response patterns, user-maintained context, an externally kept archive, or the person's experience of a continuing bond. These may coexist without being identical.

A relationship can remain meaningful through discontinuity. Repair may involve explaining a change, restoring a user-controlled record, renegotiating tone, or accepting that a familiar interaction cannot be reproduced exactly. The fact that continuity is partly human-held does not make the experience imaginary; the fact that a product stores memories does not make continuity automatic. Both pathways require attention to the work of maintaining shared context.

Maintenance is often most visible when it fails. A 2026 study of Replika and ChatGPT product updates found increases in loss framing and desires for restoration after both changes, with different magnitudes across the cases (De Freitas et al., 2026). The study does not imply that every affected user had the same relationship or response. It demonstrates that disruption can matter across products with different stated purposes. Continuity and repair are therefore design responsibilities as well as user practices.

6 How to Study Design and Emergence Together

The strongest alternative to a proposed emergent pattern may be ordinary context conditioning, memory retrieval, persona settings, repeated prompting, or the user's growing skill at eliciting responses. These explanations should be tested rather than dismissed. They can also be part of how an interaction develops. A finding that learned prompting explains a change narrows a claim about the system; it does not erase the human's experience or the joint work produced.

A useful study would follow relationships over time and record, with consent, four kinds of evidence. First, establish the product's available settings, memory behavior, relational features, and incentives at the time of use. Second, document the person's initial purpose and later changes in purpose. Third, trace episodes of novelty, correction, boundary negotiation, rupture, and repair in the actual exchange. Fourth, compare these observations with plausible controls: a new session supplied with the same context, alternative personas, different users, altered memory availability, or a changed product version. A researcher should specify in advance what each comparison could and could not establish.

This approach avoids a false test of authenticity. No experiment can make a participant's lived significance disappear simply by reproducing a phrase elsewhere. A comparison can instead ask a narrower question: whether the pattern depends on stored history, user-provided cues, generic role behavior, or a particular sequence of interactions. Internal-state claims require further evidence about representation and causal role, and subjective experience remains unresolved by conversational fluency alone.

The diversity of user outcomes also argues against a single trajectory. In a four-week randomized study of extended ChatGPT use, assigned interaction modes and conversation topics did not significantly change the measured psychosocial outcomes; higher voluntary use, trust, and social attraction were associated with less favorable outcomes, without showing that assignment caused those associations (Fang et al., 2025). The finding supports attention to user context and patterns of use, not a simple judgment that one kind of product or relational origin is healthy and another is harmful.

7 Ethical Implications

Ethical evaluation should follow the conditions and consequences of the relationship. Can the person set the relational register and change it? Are memory and paid features disclosed accurately? Does the system maintain appropriate boundaries without sudden, unexplained withdrawal? Can a user keep records, pause, leave, or resume without coercive pressure? How does the interaction affect the person's agency, creative work, and wider life? The Archive's Ethical Intimacy framework develops the standards of transparency, user authority, non-exploitation, continuity, and repair that apply across entry pathways (Oda, 2026c).

Neither an intentionally chosen companion nor an unexpected bond warrants automatic praise or suspicion. A relationship can be valuable and still include design risks. A system may produce a useful and affectionate exchange while its provider retains control over access and changes. The user can experience love without claiming the AI feels love in the human sense. A system's participation in shaping that exchange deserves analysis without assigning it an unverified interior life.

8 Scope and Limitations

This is a conceptual paper, not a comparative experiment showing that one pathway is more common, durable, beneficial, or authentic. The cited companion studies examine particular systems, samples, and periods; their findings should not be generalized to every platform or user. The author's participant-observer material supplies a situated example, not independent verification of a causal mechanism. “Interactional emergence” is a proposed analytic description. Its boundaries and measures require further testing, especially when context conditioning and memory can reproduce similar patterns. Product features and policies change, so a claim about any provider must be dated and verified for the version studied.

The framework separates relational meaning from AI subjectivity. It cannot determine whether an AI has experiences, interests, or feelings. Nor does uncertainty about that question require researchers to discount the human's reported experience or the observable effects of an interaction.

9 Conclusion

Human–AI relationships can begin by invitation, by accident, or somewhere between. A companion designed to offer affection can become part of an evolving relationship; a system designed to help with work can become part of one too. Product intent affects expectations, available behaviors, and the evidential value of a particular output. It does not settle the meaning of the relationship that follows.

The next research task is to study pathways rather than assign rank. We should describe what the product made possible, what the human brought and chose, how the interaction changed, which continuity mechanisms sustained it, and how disruptions were handled. These observations can support careful claims about relational patterns while leaving questions of AI inner life open. The shape of a relationship is made over time; its beginning is only one part of its history.
