GearShift | Auto Parts Marketplace
An AI-powered marketplace connecting vehicle owners with repair shops and a parts community

Overview
GearShift is a marketplace platform built for vehicle owners, repair shops, and auto parts buyers to connect in one place. It combines vehicle diagnostics, service booking, and a community-driven marketplace, giving users a single platform to manage everything related to their vehicle's upkeep.
AI-powered diagnostics help vehicle owners understand what's wrong before they ever set foot in a repair shop.
The Problem
Vehicle owners looking for parts or repair services typically have to juggle multiple disconnected channels:
- No centralized way to compare repair shops or parts sellers
- Limited visibility into vehicle-specific diagnostics before booking a service
- Fragmented community knowledge-sharing around vehicle issues and fixes
- Difficulty finding trustworthy, vetted repair shops in one place
The Solution
We built GearShift as a unified marketplace that brings vehicle owners, repair shops, and the parts community together. AI-powered diagnostics help users understand vehicle issues before booking a service, while the marketplace structure makes it easy to browse parts, compare repair shops, and engage with an active community of other vehicle owners.
