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
• VIN decoding, vehicle profiles, and Mode 9 vehicle information

⚡ 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.

Graphics great. A lot of. Clear information. I really like the AI assistance.. all in all really user friendly

Have you ever wondered what's really happening under your car's hood? This app connects to your OBD2 system to provide valuable insights about your vehicle's health. It can alert you to potential issues like faulty sensors. Run a scan before your next service appointment and feel confident approving repairs because you will have a clear picture of what's truly needed.
