Why Warmth Makes Mia an Adult AI Companion
Mia is an adult AI companion because persistent memory, proactive messages, relational cues, privacy, safety, and subscriptions require adult-oriented design.
Why We Built Mia for iMessage Instead of Another App
Warmth explains why Mia lives in Messages: lower friction, one continuing thread, ordinary media, proactive contact, and the real privacy tradeoffs.
Companionship, Not Compliance: Why Mia Will Tell You No
Warmth explains why a useful AI friend should disagree sometimes, separating taste, decision friction, factual correction, safety refusal, and empty contrarianism.
How We Design an AI Check-In That Is Worth Sending
Warmth shares a six-part framework for useful AI check-ins: context, timing, new value, cadence, control, and graceful silence, with synthetic examples.
