Free Features
What You Get for Free
Every one of these tools is free to use. No credit card, no trial period. Just open the app and go.
What's Wrong?
Describe your symptoms — year, make, model, what you hear, feel, or see. The AI analyzes your problem like a master tech would and ranks the most likely causes with estimated costs and urgency.
Warning Lights
Tell it which light came on and your exact vehicle. Instead of a generic list of 20 causes, you get the 3-4 most likely for YOUR year, make, and model — plus whether you need to stop driving.
Recall Checker
Enter your VIN once. The app checks for open recalls on your vehicle and alerts you when new ones are issued. Recall repairs are always free — but only if you know about them.
Maintenance Schedule
Enter your vehicle and current mileage. The app builds a complete maintenance schedule and sends alerts when oil changes, tire rotations, and fluid flushes are due.
How Do I?
Step-by-step instructions for basic car tasks — jump starts, tire changes, fluid checks, wiper replacements. Tailored to your exact vehicle.
First Car Owner
New to owning a car? The app walks you through everything — what all the controls do, how to pump gas, what fluids to check, and when to get service.
Unlock Everything
Pro gives you unlimited diagnostics, deeper tools, and features that save you real money at the shop.
Understand Your Estimate
Upload or type in a shop estimate. The app tells you if the price is fair, what each line item means, and what to push back on.
Reply to My Technician
Your shop said something you don't understand? Type it in. The app translates tech-speak into plain English and tells you how to respond.
My Car's Tech
Every specification for your exact vehicle — engine, transmission, fluid capacities, tire sizes, torque specs, fuse layouts. All in one place.
How Urgent Is This?
Not sure if you can wait or need to stop driving? Describe the issue and the app gives you a clear urgency rating with next steps.
Before You Buy
Thinking about buying a used car? Enter the vehicle details and the app flags common problems, known issues, and what to inspect.
My Glove Box
Store your VIN, insurance info, registration, warranty details, and service records. Everything about your car in one secure place.
How It Works
Tell It Your Problem
"2019 Honda Civic, AC blows warm on passenger side, cold on driver side." The more detail you give, the better the diagnosis.
Get a Real Diagnosis
The AI ranks the most likely causes, estimates repair costs, and tells you if it is safe to drive — like a master tech would.
Walk In Informed
Know what is wrong, what it should cost, and what questions to ask. No more hoping the shop is honest.
