Tech Copilot | AI Chrome Extension for Automotive Technicians

Tech Copilot is a production Chrome extension built for automotive technicians. It works directly inside the browser as an AI assistant, helping technicians understand repair information, work with VIN-specific context, capture screenshots, and get diagnostic guidance without constantly switching between tools.

I built the Chrome extension architecture and continued developing the product across multiple paid milestones, taking it from the initial MVP into a polished live product.

Key features include:

• Manifest V3 Chrome extension • Floating browser-based AI assistant • OpenAI-powered responses • Gemini Pro RAG with VIN-specific context • Screenshot, snip and scroll capture • Conversation modes and persistent state • Usage-based free trial and monthly limits • ExtensionPay subscription integration • Freemium access and upgrade flows • Production debugging, testing and ongoing improvements

The extension is live on the Chrome Web Store and has been developed through a long-term Upwork engagement with multiple completed milestones and a 5.0 client review.
