About this app

An AI-powered OBD2 scanner — turn any Bluetooth or Wi-Fi ELM327 adapter into an intelligent diagnostic system that produces professional inspection reports. OBDAI combines live vehicle data with advanced AI to deliver real-time automotive intelligence and shareable documentation.

OBDAI includes ARIA (Automotive Reasoning & Intelligence Agent), an AI system that analyzes live vehicle data, selects relevant diagnostic tests, explains results in plain English, and now produces professional reports you can hand to a mechanic, customer, or buyer.

📄 PROFESSIONAL DIAGNOSTIC REPORTS (NEW)

ARIA now produces professional inspection documents — not screenshots, not copy-paste, real deliverables:

• "Powered by ARIA" appears on page one — AI authorship, not a chatbot response
• Includes VIN, Year, Make, Model identification
• Full diagnostic findings with recommendations
• Shareable with mechanics, customers, or buyers
• Perfect for pre-purchase inspections, selling your car, or fleet records

🧠 AI-POWERED DIAGNOSTICS

• Vehicle-aware intelligence grounded in live OBD2 sensor data
• Smart VIN decoding — ARIA asks for your VIN and identifies your exact vehicle automatically
• Plain-language explanations for check-engine lights and symptoms
• Tap any diagnostic trouble code (DTC) to instantly see causes, severity, and next steps
• Predictive maintenance by identifying trends before failures occur
• Visual repair guidance with step-by-step videos and component photos
• Mechanic-grade answers to questions like "Is this safe to drive?" or "What part do I need?"

Works across multiple vehicles with cloud history and cross-platform sync (Android, iOS, Windows).

🔧 FULL OBD2 SCANNER FEATURES (FREE)

• Read and clear diagnostic trouble codes (DTCs) — Stored, Pending, and Permanent
• Live data streaming for 150+ parameters with gauges and graphs
• Custom dashboards for driving, towing, racing, or troubleshooting
• Emissions readiness checks for smog and inspection prep

⚡ WHY OBDAI IS DIFFERENT

• ARIA produces professional deliverables — not just answers, documents
• Smart VIN identification — US, European, even partial chassis numbers
• AI answers grounded in real vehicle sensor data
• Works with standard ELM327 adapters — no proprietary hardware required
• Designed by automotive diagnostics professionals using modern AI systems
• Constant updates — OBDAI improves with every scan and conversation

There are two categories now: scan tools with AI features, and AI agents that produce professional deliverables. OBDAI with ARIA is the only product in the second category.

Ratings and reviews

I must admit I never thought about adding an ai system to the app, very innovative. App is well thought out, graphically pleasing, and easy to use by non-automotively inclined users. I recommend this app for all cars. However there is 1 little graphical design issue. I recommend hiding the navigation and notification bars while the app is open. I had this issue with some of my early apps. It is an easy fix.

a long waist of time. I can't change from Celsius to fahrenheit and connection issues are frequent.

Tech dept earned their money with me, my inexperience. works good very interesting Thanks Again
