## What is Auto AI Diagnostics?

Your check engine light is on. Now what?

Auto AI Diagnostics turns your iPhone into an AI-powered car diagnostic tool. Plug a Bluetooth OBD2 adapter into the port under your dash, tap scan, and AXEL — your AI shop foreman — reads the fault codes straight from your car's computer and explains what's going on in plain English or Spanish: what's happening, how serious it is, whether it's a DIY fix or a shop job, and what to do next.

FEATURES:
• Real fault codes pulled straight from your car's computer — engine and control modules
• Automatic VIN read directly from your vehicle's ECU
• AI-powered diagnosis with evidence and an action plan — not just a code definition
• Fault code descriptions verified against the web for accuracy
• View Conditions: see the mileage, battery voltage, and speed recorded when each fault set
• Live engine data — RPM, coolant temp, battery voltage, throttle, and more
• Odometer tracking with every scan
• Scan history so you can track issues over time
• DIY repair guidance and YouTube repair video suggestions for your exact vehicle
• Ask AXEL follow-up questions about your specific car
• Works with older, pre-2008 (K-line) vehicles too
• The entire app in English or Spanish — including AXEL's AI diagnosis. Switch anytime.

WHAT YOU NEED:
A Bluetooth OBD2 adapter (ELM327-compatible, sold separately). It plugs into the OBD port under the dashboard on the driver's side — and on iPhone there's no pairing needed, the app finds it automatically.

Works with most gas-powered cars and light trucks sold since 1996 (OBD2), including many pre-2008 K-line vehicles.

Auto AI Diagnostics helps you understand your car and make informed decisions — it's information and guidance, not a substitute for a professional inspection when safety is on the line.


## Version history (last 5 releases)

### 1.3.1 — 2026-08-06

AXEL AI is still FREE during launch.

• Enter fault codes by hand — no adapter required. Type the codes off a shop quote, an AutoZone printout, or a dealer estimate, and AXEL diagnoses them like a real scan
• Repair videos linked right on the report, matched to your car and the job
• Snap a photo of your VIN to add a car, instead of typing 17 characters
• Garage artwork now covers 215 vehicles
• AXEL's module answers come back noticeably faster

Still want live scanning? On iPhone you need a Bluetooth 4.0 (BLE) OBD2 adapter — about $60. Pair it in the app, not in iOS Settings.

### 1.2.1 — 2026-07-20

AXEL AI is still FREE during launch — and this is our biggest polish update yet.

• Completely redesigned diagnostic report — cleaner fault cards, a smarter layout, and AXEL right where you need him
• Your garage now shows real artwork for 19 more popular vehicles, from F-150s to RAV4s
• Refreshed Home and Setup screens, with a new how-to video to help you get connected
• The keyboard no longer covers the chat box, plus a handful of small fixes
• Enhanced scans on VW, Audi, and Porsche now show honest evidence instead of misread codes

### 1.2.0 — 2026-07-09

The biggest diagnostic upgrade yet — and AXEL AI is FREE during launch.

• Deep module scanning validated on real BMW, Toyota, VW/Audi, Hyundai/Kia — reads airbag, ABS, transmission, cluster and more
• New "Modules Checked" card shows every system scanned and its result
• Smarter AXEL: freeze-frame evidence, Live Data guidance, shorter answers
• Fault-code accuracy fixes across all makes

### 1.1.1 — 2026-07-08

What's fixed in 1.1.1:
• Your scan reports are now protected if saving fails — you'll see a clear message and a one-tap retry instead of losing the report.
• "View report" on the Home screen's Last Scan card now opens your report correctly.
• Spanish: error and connection messages now display fully in Spanish.
• Deeper module scanning support for more vehicle brands, plus faster scans on pre-2008 vehicles.

### 1.1 — 2026-07-05

What's new in 1.1:
• Full Spanish support — the entire app, including AXEL's AI diagnosis, now speaks Spanish. Switch anytime right from the connect screen, Home, or Settings.
• More accurate fault code descriptions, verified against the web.
• See the conditions when each fault set — mileage, battery voltage, and speed — with the new View Conditions button.
• Track your odometer with every scan.
• Better support for older, pre-2008 (K-line) vehicles, including a fix for misread fault codes.
• Clearer Bluetooth setup steps for iPhone — your adapter connects from inside the app, no pairing needed.
• Fixed the Contact Us email link.
