Methodology
PointCheck uses a cutting-edge, state-of-the-art AI vision model with evidence-based verification to provide probability-based authenticity assessments for lithic artifacts.
AI Vision Analysis
Our cutting-edge AI vision model examines flake patterns, edge work, patina, material texture, and morphological features to assess authenticity indicators.
Evidence-Based Verification
Results are verified using an algorithm developed from extensive testing on a high-confidence dataset, detecting patterns that indicate potential false positives.
Consistency Check
Results are checked for verdict-score mismatches. When conflicts are detected, results are marked “Inconclusive” to prevent misleading assessments.
Our model is tested against a diversified, high-quality reference dataset* featuring artifacts with verified provenance—including museum specimens, archaeological survey finds, and pieces authenticated by certified professionals—balanced against documented modern reproductions from skilled knappers and known replicas.
Verified pieces from museum collections, professional surveys, and certified authenticators.
Documented replicas from knapper demonstrations and known modern-made pieces.
Authenticity probabilities are mapped to human-readable verdict labels:
When the model's numerical probability and categorical verdict show major contradictions, results are marked “Inconclusive.” This typically occurs with unusual artifacts, atypical materials, or items that challenge standard classification. Physical examination is recommended.
Shape, size, and distribution of removal scars
Retouch patterns, edge angles, and regularity
Shape, depth, and symmetry of hafting notches
Stone type, fracture patterns, and surface quality
Surface oxidation, desert varnish, and age indicators
Overall shape, proportions, and typological fit
Termination patterns indicating knapping technique
Grinding, thinning, and hafting modifications
