Overview

Kairos provides AI-driven identity verification: liveness detection to confirm a selfie is a real live person (not a photo or video spoof), biometric face matching between an ID photo and a live selfie, age estimation from photographs, and document authentication across more than 4,000 ID types worldwide.

Liveness detection specifically is the feature that separates real identity verification from simple face matching – without it, someone can defeat a face-match check just by holding up a photo of the person they’re impersonating. Combining that with document authentication and fraud scoring gives Kairos a full verification pipeline rather than a single-point check.

Kairos AR reports 1,000+ global business clients and over 1 billion transactions processed. New signups get 100 free API calls to test the platform before committing; detailed pricing tiers are on a separate pricing page.
