OBDAI OBD2 Scanner & ELM327 AI
AI Mechanic + Repair Videos
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Read factory Monitor Tests, track evidence across drives, spot recently cleared codes, and ask ARIA what your vehicle data means.
Turn any compatible Bluetooth or Wi-Fi ELM327 adapter into an intelligent vehicle diagnostic system.
OBDAI combines live OBD2 data with ARIA, an automotive reasoning agent that explains what the vehicle is reporting in plain English, remembers previous inspections, and creates professional diagnostic reports.
MONITOR TESTS — THE ENGINE'S OWN REPORT CARD
Read the Mode 6 self-tests run by the engine computer: catalyst efficiency, oxygen sensor response, EVAP, EGR, misfire, and more. OBDAI shows the vehicle's actual result and manufacturer limit, per ECU, without invented health scores.
TRENDS ACROSS DRIVES
ARIA preserves Monitor Test readings with each session. Ask whether a catalyst or sensor test is drifting toward its limit and ARIA compares the same evidence across recorded drives.
DRIVE-CYCLE INTELLIGENCE
OBDAI reads in-use performance counters and since-clear history so ARIA can explain whether the evidence represents one short drive or thousands of monitoring opportunities. When inspecting a used car, near-zero distance after codes were cleared is clearly identified.
TALK TO ARIA
Use hands-free conversation mode while working. ARIA listens, answers aloud, and listens again. Automotive speech recognition understands terms such as DTC, fuel trim, freeze frame, MAF, EVAP, and catalyst.
SHOW ARIA WHAT YOU SEE
Send photos of dash warnings, VIN plates, multimeter readings, scope waveforms, invoices, leaks, and components. ARIA combines images with live telematics, diagnostic history, and conversation context—and can ask for a photo when it would help.
ARIA REMEMBERS
Ask follow-up questions without starting over. Persistent vehicle memory keeps findings, declined work, and next steps available across sessions and supported devices.
FREEZE FRAME DATA
Read the sensor snapshot captured when a diagnostic code set. ARIA uses operating conditions such as engine speed, load, temperature, and fuel trim to provide useful context instead of simply repeating a code definition.
PROFESSIONAL REPORTS
Create AI-authored inspection documents with findings, recommendations, next steps, and vehicle identification. Share them with a mechanic, customer, buyer, or fleet record.

ARIA Reads the Evidence
• Monitor Tests (Mode 6): see the self-tests your engine runs on itself—catalyst, O2 sensors, EVAP, EGR and more—decoded with the manufacturer's own pass/fail limits. No fake health scores.
• Trends across drives: ARIA remembers every reading and can tell you whether a test is drifting toward its limit—before the check engine light.
• Drive-cycle intelligence: ARIA reads your car's in-use performance counters and since-clear history, so she knows whether results are mature evidence or a freshly cleared vehicle. Inspecting a used car? She'll tell you if the codes were wiped recently.
• Hands-free conversation mode: tap the headset button and just talk—ARIA listens, answers aloud, and listens again.
• ARIA can now ask for photos when a picture beats a description.
• Fixes: rock-steady subscription status on flaky networks, full conversation memory on the free tier, smarter web search.
