About MECH AI: OBD2 Car Diagnostics
One app. Every job.
MECH AI is the automotive multitool: AI Mechanic chat, OBD2 code reading, step-by-step repair guides, wiring diagrams, and parts search in one app. Whether you're a DIYer in your driveway or a pro running a shop, get clear answers and step-by-step guidance for your exact vehicle.
AI MECHANIC
Ask in plain English — or Spanish, Portuguese, Russian, German, French, or Italian. Describe the symptom ("check engine light is on", "grinding noise when I brake") and get the most-likely cause, an estimated repair cost, and a DIY difficulty rating. And when a job needs a lift or special tools, it says so.
OBD2 SCANNING
Pair a Bluetooth LE or WiFi ELM327 adapter and read stored, pending, and permanent trouble codes — free, with plain-English descriptions from a 9,415-code offline catalog. Live sensor data, emissions readiness, and VIN reading included from DIY up. Read-only: it never clears codes or flashes your ECU.
GUIDED DIAGNOSTICS
Resumable sessions that walk you through the tests in the order that rules out the cheap causes first, so you don't replace a converter when the problem was an exhaust leak.
DIGITAL GARAGE
A Vehicle Health score and service timeline per car, built around your year, make, model and mileage.
PARTS FINDER
Fitment-checked parts from Amazon and eBay, searchable by symptom or part name.
TSBs & RECALLS
Manufacturer service bulletins and NHTSA recall campaigns by model and year. Confirm VIN applicability and unrepaired status through the official lookup or your dealer.
WIRING DIAGRAMS
AI-rendered electrical, vacuum, cooling and fuel-system schematics (MECHANIC and up). OEM repair and wiring diagrams with real part numbers on AUTOSHOP.
PLANS
- FREE — with ads. 3 AI text messages and 3 photo analyses per day, OBD2 code reading, 1 saved vehicle.
- DIY — ad-free. 100 AI text messages per day, guided diagnostics, repair guides, service history, 5 saved vehicles.
- MECHANIC — 300 AI text messages and 10 AI diagrams per day, full TSB library, unlimited saved vehicles.
- AUTOSHOP — 1000 AI text messages and 100 AI diagrams per day, plus OEM repair and wiring diagrams where coverage is available. Daily usage limits apply.
- SHOP MANAGER — guided pilot for repair shops. Request onboarding to discuss team workflows and availability; not a self-service purchase.
Trial availability varies by platform and plan; check the in-app subscription screen for the current offer. Cancel anytime.
SEVEN LANGUAGES
English, Spanish, Portuguese, Russian, German, French, and Italian. The AI Mechanic answers in your language. Technical identifiers (VIN, OBD2, RPM, TSB) stay universal.
