Emotional Intelligence
In AI companions, emotional intelligence is the capability to sense user mood (e.g., happy, stressed, lonely) and tailor replies with appropriate empathy, tone, pacing, and topic shifts. Systems with higher EI often combine sentiment analysis, conversation memory, and response style controls to create comforting, human-aware interactions rather than purely transactional chat.
Practically, this can include softer replies when a user signals vulnerability, proactive check-ins after sensitive topics, and graceful conversation redirection when boundaries are reached. Emotional intelligence goes beyond memory modules by focusing on how the assistant responds, not just what it remembers.
