I'm Jon — third-generation mechanic out of Detroit. Last week, I shipped something that's been keeping me up at night: Pocket Mechanic — a hands-free AI diagnostic system that actually listens.
Not "upload a file and wait." Not "click buttons and read code definitions." Talk to it. It talks back. It understands.
The Problem I Was Trying to Solve
You're under a car. Hands covered in grease. You pull a code. You need diagnostics NOW. But your hands are dirty, your phone's in your pocket, and you're not about to stop what you're doing to type.
So you either:
- Memorize the code and Google it later (lose context)
- Yell at your buddy to look it up (interrupts their work)
- Stop working, clean your hands, use your phone (wastes 5-10 minutes per code)
That's the gap. That's what I built for.
How Pocket Mechanic Works
Full-duplex voice conversation. You talk, it listens in real-time. No "wait for the beep" nonsense. No lag. It's like talking to another tech in the bay.
- Upload your datalog once (FORScan, HP Tuners, Autel, OBD2 CSV)
- Start talking: "What's causing the misfire?"
- It analyzes the data in context of what you're saying
- Gives you root causes, ranked by severity
- Remembers your previous diagnostics (knows your customer's truck history)
- Knows localization (salt-belt fleet truck vs. highway commuter)
The Tech Stack (For the Curious)
- Voice input: Real-time transcription, no latency
- LLM backbone: Automotive-specific training (not generic ChatGPT)
- Data analysis: CAN bus visualization, freeze frame parsing, pattern recognition
- Conversational memory: Persists context across sessions
- Output: Text, voice, or shareable diagnostic reports
Current Status
Free through Memorial Day week. Full Pro access. No credit card. No auto-charge. Just talk, get answers, subscribe when you're ready.
Post-beta pricing: $49/mo basic, $99/mo pro, $199/mo team

What I Learned Building This
- Mechanics don't want to learn new tools. They want tools that fit into their existing workflow. Hands-free is the only way.
- Voice is the interface. Not buttons, not forms, not "contact sales." Just talk.
- Data context matters more than code definitions. Every tech can Google a P0300. What they need is "here's what YOUR data is telling me."
- The blue-collar SaaS market is wide open. And it's hungry for tools built by people who actually use them.
This is Grease AI's flagship feature. If you turn wrenches for a living, this was built for you.
