## What is RedlineAi?

Your car just threw a check-engine light. RedlineAi tells you what's wrong, what it costs to fix, and whether you can do it yourself — before you ever set foot in a shop.

RedlineAi turns your phone into a professional-grade OBD-II scanner and pairs it with AI that actually explains what your codes mean. No mechanic markup. No guesswork.

LIVE OBD-II SCANNER
Plug in any Bluetooth LE OBD-II adapter and read your check-engine light in seconds:
- Stored, pending, and permanent trouble codes (P, B, C, and U)
- Live engine data — RPM, speed, coolant temp, engine load, throttle, intake air
- Your VIN, communication protocol, and battery voltage
- One-tap export or share, plus a demo mode to try with no adapter

INSTANT AI DIAGNOSIS
Every code is matched to a clear, plain-English diagnosis: the most likely cause, an honest repair-cost estimate, what to check first, and exactly where to buy the part.

RECALL CHECKER
Enter your VIN and instantly see open safety recalls for your exact vehicle — so you never miss a free factory fix.

YOUR GARAGE
Save every vehicle, track service history and mileage, and get reminders before maintenance is due. Never miss an oil change again.

COMPLETE CODE LIBRARY
Look up any OBD-II trouble code, explained in plain language — severity, symptoms, common causes, and typical fixes.

ASK AI ANYTHING
Chat with an AI mechanic about any noise, warning light, or repair quote and get a straight answer in seconds, day or night.

STEP-BY-STEP REPAIR GUIDES
For DIY fixes, follow clear instructions with the tools, parts, and time you'll need — and keep the labor cost in your pocket.

FAIR-PRICE ESTIMATES
See what a repair should actually cost in your area before you walk into a shop, so you never overpay again.

Works with common BLE OBD-II adapters (Vgate iCar Pro BLE 4.0, Veepeak BLE+, and similar). A Bluetooth Low Energy ("Bluetooth 4.0") OBD-II adapter is required for live scanning and is sold separately.

RedlineAi is built for everyday drivers. Diagnostic guidance is informational and doesn't replace a certified mechanic for safety-critical repairs.

Stop guessing. Start driving with confidence. Download RedlineAi today.

### 5/5 — Good diagnostics app

*2026-07-22*

I have been using this at my shop and it has been helping me diagnose cars and telling me codes that even my expensive OBD scanner does not even tell me.

### 5/5 — BEST APP FOR MY CAR

*2026-07-18*

Had a bunch of noises and random things coming from my car and I put them into redline and it told me exactly what to do to fix it and where to get the parts I needed. I was about to spend 700 at the dealership good thing I didn’t continue with them!!!
