Roast Grader
AI-powered coffee quality assessment. Analyze roast color and get AI-assisted preliminary green bean grading with your smartphone camera.
Note: Camera-based analysis is a screening tool, not a replacement for physical inspection or professional cupping. Lighting, angle, and camera quality all affect accuracy. Borderline assessments may differ from a certified Q-grader examining the same sample in person.
