Features
Everything you need to understand your car
MechanicAI pairs plain-English explanations for thousands of trouble codes, powered by AI, with analysis that knows your specific vehicle. Here's how it works under the hood.
Core technology
Two layers of intelligence
Layer 1 — Instant local lookup. The moment a code is read, MechanicAI matches it against a built-in library of common trouble codes. You get the definition, severity, and affected system instantly. This works offline — no internet required.
Layer 2 — AI contextual analysis. The AI goes deeper. It considers your specific vehicle — year, make, model, mileage, modifications, and scan history — to explain what the code actually means for your car. Not just the textbook definition, but the likely cause, typical repair cost, and what to do next.
P0171ModerateLayer 1 — Code definition
System Too Lean (Bank 1)
Layer 2 — AI analysis
Your 2019 Honda Civic's intake manifold gasket may be failing. Common at this mileage. Typical repair: $200–$400. Difficulty: 3/5 — intermediate DIY.
Vehicle: 2018 Civic Si
P0420ExpectedSmart context
Your mods change the diagnosis
Tell MechanicAI about your modifications — intake, tune, exhaust, suspension. The AI interprets codes differently for modified vehicles because a P0420 on a stock Civic means one thing. On a Civic with a catback exhaust, it means something else entirely.
What to do next
Three paths forward — always clear, always honest
DIY fix
Get the exact parts you need with links to buy them. Watch step-by-step repair videos. See difficulty ratings (1–5 wrenches), estimated time, and tools required.
Informed shop visit
Know what to tell the mechanic. Get fair price ranges for your area. Spot upsell red flags before they happen.
Safety-critical alert
Brake, airbag, steering, or fuel system faults trigger immediate "do not drive" warnings. These are hardcoded and cannot be overridden by AI. Your safety comes first.
Conversational
Ask follow-up questions in plain English
Not sure what the diagnosis means? Ask. Want to know if you can drive to work tomorrow? Ask. MechanicAI remembers your car, your scan, and your conversation.
Suggested question chips help you dig deeper without knowing the right terminology.

See what your engine sees
Live readouts for the engine's key vitals — RPM, coolant, throttle, fuel trims, load and more. Gauges update once per second while you drive.
Perfect for monitoring a known issue, verifying a repair worked, or just understanding how your car runs.
Memory
Every scan, saved and searchable
Every diagnostic scan is saved with the date, codes found, and full AI analysis. Track recurring issues over time. Spot patterns before they become expensive problems.
Per-vehicle history means you can manage multiple cars from one device.

Safety first
Some things can't wait
When MechanicAI detects a fault in a safety-critical system, it overrides everything else with a clear warning.
Do Not Drive
ABS Module Fault
Brake system may not function correctly under emergency braking. Have your vehicle towed to a qualified mechanic immediately.
This report is an informational aid generated from your vehicle’s on-board diagnostics during a short drive. It is NOT a substitute for a professional pre-purchase inspection by a licensed mechanic. OBD2 cannot detect many serious problems — including frame/structural damage, rust, accident history, odometer fraud, and many transmission and suspension faults. Do not make a purchase decision on this report alone.
Stop guessing. Start knowing.
Works with most popular ELM327-compatible Bluetooth adapters and most 1996+ vehicles with an OBD-II port. Download MechanicAI and understand your car.
