About this app

Decode your check engine light in seconds. OBD2AI is the AI-powered OBD2 scanner and car code reader that turns any ELM327 Bluetooth adapter into a complete car diagnostic tool — read fault codes, get plain-English explanations, and get repair guidance for your specific vehicle

No mechanic jargon. No shop diagnostic fees. Just clear answers for your car.

▸ KEY FEATURES
• OBD2 Code Reader – Scan stored, pending, and permanent DTC fault codes from any OBD2-compliant car, truck, or SUV (1996+ in the US, 2001+ in the EU).
• AI Diagnosis – Every code is translated into a plain-language explanation tailored to your year, make, and model. Severity, likely causes, and typical repair costs included.
• AI Repair Guides – Get custom repair guidance.
• Live OBD2 Data – Stream real-time sensor readings: RPM, coolant temp, fuel trims, O2 sensors, MAF, throttle, vehicle speed, and more. Save live data snapshots for later review.
• Freeze Frame Capture – Save the exact sensor snapshot from when a fault triggered, so intermittent issues don't slip through.
• Multi-Vehicle Garage – Track every vehicle you own. Each car has its own scan history, mileage log, and active code list with severity badges.
• Scan History & DTC Search – Every diagnosis is saved offline. Search past scans, compare results over time, or look up any standard DTC in the built-in code library.
• Import & Export – Bring scans in from other OBD2 tools, back up your data, or share results with your mechanic in one tap.

▸ WHY OBD2AI BEATS A REGULAR OBD2 SCANNER
Most OBD2 apps dump cryptic codes on you and stop there. OBD2AI uses advanced AI to translate raw OBD-II data into a real diagnosis — like having a knowledgeable mechanic in your pocket. Every explanation is specific to your vehicle, not a generic web copy-paste.

▸ WORKS WITH ANY ELM327 BLUETOOTH ADAPTER
OBD2AI is compatible with the affordable ELM327 Bluetooth OBD2 dongles you can buy online for under $20. No proprietary or expensive scan tool required.

▸ PRIVACY FIRST
• No account required
• Scans are stored locally on your device
• We don't collect, track, or sell your data.
• Only minimal diagnostic context is sent to the AI backend to generate an explanation

▸ PERFECT FOR
• DIY mechanics and weekend wrench-turners
• Drivers who want answers before visiting the shop
• Used-car buyers running pre-purchase inspections
• Owners tracking multiple vehicles in one garage
• Anyone tired of paying $100+ for a basic diagnostic scan

▸ GET STARTED IN UNDER 60 SECONDS
1. Plug an ELM327 Bluetooth OBD2 adapter into your car's OBD2 port (usually under the dashboard).
2. Pair it in your Android Bluetooth settings.
3. Open OBD2AI, add your vehicle, and tap Scan.

Your first AI car diagnosis is ready in seconds.
▸ REQUIREMENTS
• Android 8.0 or higher
• Bluetooth ELM327-compatible OBD2 adapter (sold separately)
