About GSB DIAG

GSB DIAG helps everyday vehicle owners understand repair estimates, diagnostic codes, warning lights, and symptoms before they authorize major work.

Built around more than 20 years of automotive parts, repair, shop-management, mobile-mechanic, and supply-chain experience, the platform combines structured AI analysis with optional expert review.

Our role is education and second-opinion guidance—not a definitive diagnosis without inspecting the vehicle. We translate technical information, highlight useful questions, and help drivers have a better conversation with the shop.
