Interhuman AI – Social Intelligence API

Interhuman AI is a social intelligence API that detects behavioral signals from video, audio, and text. Unlike traditional tools that focus only on words or sentiment, this API analyzes how people communicate — not just what they say. By processing voice, facial expressions, body language, and text together through a single endpoint, it provides a richer understanding of human interaction.

What It Detects

The API identifies 12 distinct social signals, including hesitation, confusion, confidence, agreement, frustration, skepticism, engagement, and uncertainty. Each detection is accompanied by timestamps, probability scores, and a human‑readable explanation of the observable cues that triggered it. This transparency helps developers and product teams understand not just the output, but the reasoning behind it.

Beyond individual signals, the API offers continuous engagement tracking and a Conversation Quality Index scored from 0–100 across five dimensions. This holistic view allows applications to measure and improve communication effectiveness in real time.

Built for Developers and Product Teams

Interhuman AI is designed for those building conversational AI and communication‑focused products. With one REST endpoint, structured JSON responses, and token‑based authentication, integration is straightforward. No machine learning expertise is required, making it accessible to teams of all sizes.

Potential use cases include:

• Sales coaching tools that highlight hesitation or confidence during calls.

• AI tutors that detect confusion and adjust explanations accordingly.

• Meeting copilots that track engagement and flag when consensus is missing.

• Interview platforms that surface signals of skepticism or agreement.

• Communication training apps that provide feedback on body language and tone.

• User research tools that measure participant engagement.

• Healthcare applications that monitor patient frustration or uncertainty.

Powered by Inter‑1

At the core of the API is Inter‑1, a multimodal model purpose‑built for social signal detection. Grounded in behavioral science and validated with psychologists, it goes beyond sentiment analysis or emotion AI. Instead of vague emotional labels, it delivers specific, actionable behavioral signals that applications can act on immediately.

This precision makes it especially valuable for professional contexts where accuracy and clarity matter. Developers can trust that the signals are not just guesses, but grounded in observable human behavior.

Why It Matters

Communication is more than words. Tone, facial expressions, and body language all shape meaning. By capturing these signals, Interhuman AI enables applications to respond in ways that feel more human, empathetic, and effective. Whether improving sales conversations, enhancing learning experiences, or supporting healthcare interactions, the API helps bridge the gap between human nuance and machine understanding.
