Problem
Auto repair shops are forced to juggle multiple disconnected tools for intake, diagnostics, estimating, parts ordering, and payments, leading to lost information between handoffs and slow, error-prone workflows. Technicians waste time retyping data and bouncing between labor guides and supplier websites, while customers face unclear estimates and phone-tag approval processes.
Solution
CarSignal is an AI-powered operating system that unifies every step of the auto repair workflow—intake, diagnostics, estimates, scheduling, and payments—into one connected record. The platform’s Diagnostic Copilot ingests OBD codes from any existing scan tool, weighs them against the customer’s complaint and vehicle history, and recommends the most likely repair with OEM-grounded reasoning and confirmation steps. Repair Buddy provides an AI chat interface grounded in OEM data for instant access to torque specs, fluid capacities, and component locations. The system also generates plain-English estimates with itemized parts and labor, enabling customers to approve or decline each line directly from their phone. Approved parts are automatically priced and ordered from suppliers, while an iOS app gives the entire shop team access to job creation, invoicing, and payments from the bay.
Target Audience
Primary customers are independent auto repair shop owners and service managers, from single-operator facilities to multi-tech shops, who want to modernize operations and reduce administrative overhead.
