Interhuman AI

Interhuman AI is a social intelligence API that detects behavioral signals from video, audio, and text. It analyzes how people communicate — not just what they say — by processing voice, facial expressions, body language, and words together through a single endpoint.

The API detects 12 social signals including hesitation, confusion, confidence, agreement, frustration, skepticism, engagement, and uncertainty. Each signal comes with timestamps, probability scores, and a human-readable explanation of the observable cues that triggered it. Responses also include continuous engagement tracking and a Conversation Quality Index scored 0–100 across five Dimensions.

Built for developers and product teams building conversational AI. Integrate social intelligence into sales coaching tools, AI tutors, meeting copilots, interview platforms, communication training apps, user research tools, and healthcare applications. One REST endpoint, structured JSON responses, token-based auth, no ML expertise required.

Powered by Inter-1 — a multimodal model purpose-built for social signal detection, grounded in behavioral science and validated with psychologists. Not sentiment analysis. Not emotion AI. Specific, actionable behavioral signals your application can act on.
