GreaseGenius puts a professional-grade AI mechanic in your pocket - powered by Claude AI and built for every driver who's ever stared at a check engine light and had no idea where to start. Whether you're a seasoned wrench-turner or you've never popped a hood in your life, GreaseGenius gives you the tools, knowledge, and confidence to understand exactly what's wrong with your vehicle and what to do about it.
-- INSTANT AI DIAGNOSIS --
Describe your car's symptoms in plain English - grinding brakes, rough idle, hesitation on acceleration, strange smells - and GreaseGenius's AI diagnoses the most likely causes, rates the severity, tells you whether it's safe to keep driving, and gives you a clear repair roadmap. No jargon. No guesswork. Just answers.
-- OBD-II CODE LOOKUP --
Plug in your OBD-II scanner and enter any trouble code to get a full breakdown: what the code means, what's causing it, how urgent it is, what parts you'll need, and whether it's a DIY fix or time to see a pro. Our database covers thousands of codes across all major makes and models - Ford, Chevy, Toyota, Honda, RAM, GMC, Dodge, Jeep, and more.
-- STEP-BY-STEP REPAIR GUIDES --
From brake pad replacement to oil changes, spark plugs to serpentine belts - GreaseGenius walks you through every repair with clear, numbered instructions written for real people. Each guide includes the tools you'll need, estimated time, parts cost, and difficulty rating so you know exactly what you're getting into before you start.
-- AI MECHANIC CHAT --
Got a question mid-repair? Not sure if that noise is serious? Ask our AI mechanic anything and get a straight answer in seconds. It knows your vehicle's year, make, model, and history - so every answer is specific to your car, not generic internet advice.
-- VEHICLE PROFILES --
Add all your vehicles and track maintenance schedules, repair history, and upcoming service intervals in one place. Never miss an oil change or forget when your last brake job was.
