Stone grading is broken.
We fixed it.
Replace subjective human error with precision AI analysis. Epistable brings algorithmic certainty to the world's most beautiful natural materials.
Precision Infrastructure
AI Quality Grading
Neural networks trained on 10,000+ stone samples to identify micron-level fissures and variations.
QR Traceability
Every slab is etched with a digital identity. Track from quarry floor to architectural install.
Yield Optimization
Maxmize your cut-patterns by predicting structural integrity before the diamond saw touches the surface.
Remote Inspection
Buyers can verify quality from anywhere in the world without flying to the factory floor.
Digital Certification
Instant PDF grading certificates authenticated on the blockchain for zero-tamper security.
ERP Integration
Seamlessly push grading data into your existing inventory management and financial systems.
The Precision Protocol
Inspect
High-fidelity optical sensors capture the slab's unique topographic and aesthetic data.
AI Grade
Epistable AI compares the data against global standards to assign a definitive grade.
Trace
A unique QR identifier is generated, linking the physical slab to its digital twin.
Export
Detailed inspection reports and export documentation are generated automatically.

Frequently Asked Questions
How accurate is the AI compared to a human inspector?
In blind tests, Epistable AI identified 15% more structural fissures that were invisible to the human eye under standard lighting conditions.
Can it be used for all types of natural stone?
Currently, our models are optimized for Marble, Granite, and Sandstone. Quartz and Onyx support is in beta.
Does the hardware require a specialized setup?
Our modular camera rigs can be mounted on most standard overhead crane systems or inspection tables in less than 4 hours.
