## What is MECH AI?

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 — powered by AI trained for cars. Whether you're a DIYer in your driveway or a pro running a shop, get clear answers, accurate fitment, and step-by-step guidance for your exact vehicle.

AI MECHANIC
Ask in plain English (or Español, Français, Português, Deutsch, Русский). Describe the symptom — "check engine light is on" or "grinding noise when I brake" — and get the most-likely cause, an estimated fix cost, and a DIY difficulty rating. Built for cars: knows TSBs, recalls, and exact part numbers.

GUIDED DIAGNOSTICS
Hit a fault code? Run a guided OBD2 session. MECH AI walks you through symptom-narrowing questions, suggests the most-likely component, and gives you the next test to confirm — like having a seasoned technician on speakerphone.

VEHICLE HEALTH SCORE
A live score for every car in your garage. Critical issues flagged the moment they appear. Maintenance on a clock. Built around your year/make/model — not generic intervals.

PARTS CENTER
AI-verified fitment from Amazon, eBay, RockAuto, and more. Skip the "will this fit my car?" forum thread. Search by symptom or by part name, see options across stores, side-by-side.

MECH MODS
AI-curated upgrade and modification ideas for your exact year, make, and model — from intake to suspension — each with parts that actually fit.

TSBs & RECALLS
Manufacturer service bulletins matched to your exact year, make, and model. Live recall lookup. Never miss the OEM-known fix for your car.

MULTI-VEHICLE GARAGE
Add unlimited vehicles with VIN scanning. Switch instantly. Per-vehicle history, maintenance, and AI context that remembers your specific car.

WIRING DIAGRAMS (Mechanic tier+)
AI-rendered electrical schematics. Look up any system, trace any wire. OEM-level coverage at indie-shop prices.

MECH ACADEMY (early access)
Learn how your car works and how to fix it — bite-size, gamified lessons with clear diagrams and hands-on exercises. New this release: learning diagrams, sound effects, and a refreshed look.

### 1/5 — 5 Free messages

*2026-07-04*

5 free messages daily then you have to pay more corporate greed slop, messes up most of the common issues anyway absolutely trash.

### 1/5 — Dismal!

*2026-06-29, version 1.3.10*

Dismal failure unfortunately!  I had high hopes for this app but even if signing up presents major issues then what other problems will emerge? Sorry but it’s a no  from me. 😬

### 1/5 — Shonky garbage

*2026-06-22*

This is the shonkiest app on the planet. It’s clunky. When you try and ask a question you immediately hit a paywall. 

Horrible

### 4/5 — Good but a little slow

*2026-06-20*

This program is accurate and has helped me a lot so far

### 5/5 — Mech AI is truly a life changing app

*2026-06-18*

It really a helps the newer generation of techs that are just learning to diagnose a car properly based on the customers words and descriptions of symptoms, also it makes me feel more independent in my own work letting me attempt to figure out the underlying issue based on my own educated guess’s

**Developer response:** Thank you so much for the 5-star review — it genuinely makes our day. Glad MECH AI is working for you! — The MECH AI Team

### 3/5 — Content

*2026-06-17, version 1.3.10*

Was really helpful, the detailed repair guide for my 2014 WRX was quick and easy

### 1/5 — ZERO stars

*2026-06-04, version 1.3.0*

Every suggestion or repair was wrong

### 5/5 — Best Ai Mechanic app out there

*2026-05-31*

Guys, this is the best app I’ve ever used it gives you everything. Repair guides, parts suggestions, OEM Part numbers, Diagnostic codes break down, and many more. This is a must have for beginners, moderates, and experienced mechanics.

**Developer response:** What a review — thank you! Repair guides, parts, OEM numbers, and code breakdowns all in one place is exactly what we set out to build, for beginners and pros alike. Grateful to have you with us. — The MECH AI Team

## Version history (last 5 releases)

### 1.3.42 — 2026-08-28

Bug fixes and stability improvements — more reliable garage, VIN scanning, maintenance reminders, and subscription/billing.

### 1.3.41 — 2026-08-27

Diagnostics got smarter and more honest: see the evidence for each likely cause, the single best test to run next, and log its result with one tap. Get an early answer when confidence is high, and pick up an unfinished diagnosis exactly where you left off — the resume card now shows your current question and next test. Also: a permanent Garage tab, direct vehicle editing, accurate bonus-credit balances, faster paid-plan recognition, and a failed diagnostic never costs a credit.

### 1.3.40 — 2026-08-15

Improved subscription purchase reliability, clearer billing status, and general stability fixes.

### 1.3.39 — 2026-07-30

Repair Guides go deeper this release: jump between sections with the new guide navigator, review a Before You Start safety block, and ask the AI Mechanic about any individual step. Guides now lead with diagnosis, flag engine/trim variants, and say when to stop and see a pro. Also fixed: the app screen could pinch-zoom out of alignment, and subscription messages now make clear whether a feature needs an upgrade or you've hit a daily limit. Plus checkout and stability fixes.

### 1.3.38 — 2026-07-22

Fixed: AI Wiring Diagrams, Repair Guides, and long AI Mechanic answers could fail with 'connection lost' while still counting against your daily limit. Long generations now complete reliably, slow networks retry automatically, and error messages are clearer. Plus subscription sync fixes and stability improvements.
