Includes inspector hours, customer recovery costs from defect leakage, and managerial time for quality reporting.

Challenge

Visual inspection relied on senior inspectors' experience, leading to inconsistent standards and missed defects. Paper-and-Excel records made monthly quality reports a full-day effort.

Approach

Integrated capture → AI first-pass → inspector review → record into a single web app. The AI model was trained on the customer's own pass/fail images for both accuracy and business fit.

Implementation

Edge devices on the inspection line upload images directly to Supabase Storage. Supabase Edge Functions call OpenAI Vision combined with a fine-tuned internal model. All inspection history is preserved end-to-end for traceability.

Results

Inspection time dropped ~60%; defect leakage fell from 12/month to 2. Quality meeting prep went from 8 hours of manual work to 30 minutes of automated generation. Inspector retention also improved.

VOICE

The AI flags suspicious areas in advance, letting inspectors focus on what truly needs human judgment. New hires get up to speed much faster too.
