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.

Obd2 and AI will be the future **Developer response:** Hi tinpardo! Thank you so much for recognizing the potential of OBDAI - you're absolutely right that OBD2 + AI is the future, and we're thrilled to be leading that revolution! I'm sorry you're experiencing connection issues with your adapter. OBD2 compatibility can be tricky since there are hundreds of different adapters with varying chip sets and protocols. A few quick things that often help: Try pairing the adapter in your phone's Bluetooth settings first, then connect through OBDAI. Make sure your vehicle is running since some adapters need power. Check if your adapter supports your vehicle's protocol as some older cars use different standards. We've actually helped thousands of users get connected successfully! If you'd like to share your adapter model and vehicle info, I'd be happy to provide specific troubleshooting steps. Also exciting news - we just launched Visual AI in our latest update with embedded repair videos and component photos. Once you get connected, you'll see why we believe OBDAI is already transforming how people understand their vehicles! Would love to help you get the full OBDAI experience. Feel free to reach out anytime at support@ontarioanalytics.com We're actually considering offering our own certified adapter soon to eliminate these compatibility headaches entirely! Best regards, Daniel and the OBDAI Team ### 1/5 — Won’t connect to interface *2025-05-20* This app will not connect to my VEEPEAK PRO WiFi OBD2 scanner. Other apps connect properly. **Developer response:** Hi XYZSamSXYZ, Thanks for reaching out about the VEEPEAK PRO WiFi connection issue. I'd like to help you get this resolved! Since other apps are connecting properly to your VEEPEAK PRO, this sounds like a configuration issue we can troubleshoot. Could you help me with a few details: 🔧 Technical Info Needed: What IP address is your VEEPEAK PRO using? (Usually 192.168.0.10 or similar) What port is it configured for? (Typically 35000) Are you connecting to the VEEPEAK's WiFi hotspot directly, or through your home WiFi network? What WiFi network name does the VEEPEAK create? (Usually something like "WiFi_OBDII" or "VEEPEAK_xxxx") 📋 Also Helpful: Which other apps successfully connect to it? Any error messages you see in OBDAI when attempting to connect? This will help me determine if it's a network configuration issue or something specific to OBDAI's connection handling. We've had great success with VEEPEAK devices, so let's get yours working! Daniel OBDAI Development Team ### 5/5 — Excellent Car Scanner *2025-03-10* Gives me all the features the others charge for free. The AI chat is very cool. It knows all the details of your current trip or scan. ### 5/5 — Know Your Car!!! *2025-02-08* I just started using this diagnostic tool, and I’m amazed at how intuitive it is—even for someone who isn’t mechanically inclined. The instructions are crystal clear, and you don’t need to be a pro to figure it out. Before your next trip to the mechanic, this tool empowers you with a clear understanding of your vehicle’s issues, so you’re never in the dark. Often, it detects simple fixes you can tackle yourself, saving time and money. If you’re unsure, download the app and try it—you’ll be hooked. Plus, the Pro Version unlocks AI-powered diagnostics for even deeper insights. Seriously, this is a game-changer for car owners! ## Frequently asked questions about OBDAI OBD2 Scanner & ELM327 AI ### What is OBDAI?

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. ### 2.40 — 2026-06-22 v2.4 — ARIA Can Talk, Listen, and See ARIA gained a voice. Push-to-talk input, spoken responses, photo capture, and a smarter chat experience. • NEW: Push-to-talk voice input — tap the mic and speak your question. Live transcription on screen, auto-sends after you pause. Speech recognition tuned for automotive vocabulary — DTCs, fuel trim, freeze frame, MAF, EVAP, catalyst. • NEW: ARIA speaks back — flip the voice toggle and ARIA reads her answers aloud in a natural voice. Tap the mic while she is speaking and she stops to listen. Real back-and-forth conversation. • NEW: Photo capture in ARIA chat — snap a photo of a multimeter reading, scope waveform, VIN plate, recall letter, repair invoice, or anything else. ARIA reads it and combines it with everything she already knows about the vehicle. Up to 5 photos per message. • NEW: Live progress indicator — see what ARIA is actually doing in real time: reviewing session data, checking codes, analyzing live data, searching the web. No more blank spinner. • FIXED: No more double-sends — input locks while ARIA is working and your draft text is preserved. • FIXED: Self-healing conversations — dropped connections no longer permanently break chat threads. • IMPROVED: ARIA can now reference up to 200 past inspections per vehicle (was 10). • FIXED: Screen rotation no longer forces dashboard view from other screens.

No more re-introducing herself every turn. No more starting over. • NEW: Freeze Frame Data — When a code sets, your car captures a snapshot of every important sensor at that exact moment. OBDAI 2.2 reads that snapshot — RPM, coolant temperature, fuel trims, throttle, mass airflow — and ARIA uses it to give you a real diagnosis instead of a generic guess. • NEW: Durable Session Capture — Force-close the app, lose Bluetooth, let your phone sleep mid-scan. OBDAI doesn't lose your data anymore. Every reading is written to your device as it happens and uploaded automatically when you reconnect. • NEW: ARIA on the Web (PRO) — Continue your conversation from any browser at dashboard.obdai.app. Start on your iPhone, finish on your Mac. • IMPROVED: The most advanced AI models available now powering Premium and PRO — faster reasoning, better edge cases, sharper diagnoses on older vehicles and intermittent gremlins.
