AI Personality Profiling
FromaSinglePhoto
Backed by psychology, powered by statistical personality modeling. Mindreader Face API analyzes facial patterns to predict personality with up to 85% accuracy.
Beyond Simple Face Detection
We don't just see a face. We see the personality behind it. Powered by advanced computer vision and psychological modeling.
No Quiz Required
Traditional personality assessments require 50+ questions and 20 minutes of user time. Mindreader Face API delivers comparable insights instantly from a single photo, removing friction entirely.
MBTI Prediction
Predicts likely MBTI types with confidence scores based on facial micro-expressions.
Big Five Traits
Maps facial features to the Big Five personality traits (OCEAN) model.
Use Cases
Why It Matters: Sales, hiring, coaching, dating, teamwork — the moment you understand someone's natural operating style, you communicate better, close faster, and build trust sooner.

A Bayesian, Theory-Grounded
Personality Model
Mindreader Face API combines classical personality theory, MBTI probability distributions, and real-world co-occurrence data from extensive validation studies with uncertainty quantification.
Hybrid Model Architecture
We don't hallucinate personality. We infer probabilities using a two-layer system: • Layer 1: Facial embeddings → Statistical personality representations. • Layer 2: Bayesian conversion — Combining theory with real user data for MBTI and Big Five outputs.
Dynamic Priors
The system uses adjustable pseudo-count priors that reflect theory strength. As we add more users, data gradually dominates and theory influence fades safely, ensuring zero-probability issues never occur.
Falsifiable & Adaptive
If reality shows certain personality types correlate differently with facial features than expected — our model updates. It learns. It adapts. It improves over time.
Probabilistic Expression
No determinism. No identity claims. Only likelihoods — with explicit confidence scores.
Bayesian Laplace Smoothing
We use Bayesian Laplace Smoothing with +1 for all 16 types, ensuring robust predictions even with limited data. This approach prevents overfitting while allowing the model to learn from real-world patterns.
"We combine a theoretically justified prior with smoothed empirical evidence."
