Understand the relationships
ARIA connects monitor results, operating conditions and parameter behavior.
Bring ARIA the symptom on your next problem car. She can choose the readings, watch for relevant changes and schedule follow-ups while you work through the evidence. Reopen the recorded drive and keep the findings with your Pro reporting tools.
Tell ARIA what the car is doing. She can choose available readings, set a timed follow-up and watch for the change that matters, so you can follow a diagnostic plan without building one yourself.
Ask ARIA what changed, how the readings fit together and what deserves a closer look. Explore Mode 6, live parameters, Freeze Frame and your vehicle’s history.
Connect your J2534 VCI on Windows and put ARIA to work on the next problem car. She selects the readings, follows the evidence and directs the next test. As soon as you get your license key, download the Windows app and fire it up.
For Shops & Mobile Mechanics
Let ARIA coordinate a diagnostic plan with five simultaneous watches and check-ins.

Bring ARIA the symptom on your next problem car. She can choose the readings, watch for relevant changes and schedule follow-ups while you work through the evidence. Reopen the recorded drive and keep the findings with your Pro reporting tools.
An intermittent-hesitation plan might watch speed entering a test range, coolant reaching a needed condition, one supported fuel-trim threshold and two timed reviews. That uses five combined slots; conditions depend on the vehicle and test.
2015 Chevrolet Express 2500 4.8L — P0101 / P0171 / P0174 / P0449
ARIA — after drive test
“Both banks are affected almost equally. Under load, LTFT climbed to ~29.7% on both banks. That makes a bank-specific intake gasket leak less likely and points more toward a shared cause — unmetered air after the MAF.“
TECH
“I found an intake leak.”
ARIA
“That fits the data perfectly. A leak after the MAF lets in unmetered air — both banks go lean. That explains P0171 + P0174 together and a likely false P0101.“
ARIA — final clean test verdict
“The intake leak repair worked.” LTFT dropped from ~+29.7% to +8–10% on both banks.
Before
+29.7%
LTFT both banks
After
+8–10%
LTFT both banks
TECH
“Very good. I manually tested the vent solenoid and it was in fact faulty so I am confident this fixed it. Awesome, thank you!“
Real OBDAI PRO session. The tech almost replaced a MAF sensor — ARIA’s fuel-trim analysis sent him to the actual leak instead.
✨ Now Available
ARIA now generates customer-ready service documents — not just diagnostic reports. Every PRO report can include:
🔧
Repair Estimates
Real pricing for identified issues — parts & labor ranges your customer can understand
📋
Maintenance Schedule
Mileage-based service items injected automatically — 100K service, timing belt, fluid changes
✍️
AI Edit & Print
Tell ARIA to adjust estimates, add notes, remove items — then print from any computer
Scan from your phone. Edit and print customer reports from your computer.
One signed estimate covers your entire year of PRO. Everything after that is yours.
📄 Branded Diagnostic Reports
Your logo. Your shop name. Your phone number. On every report you generate. Hand a customer a professional PDF and they understand why the diagnostic fee exists. This isn’t cosmetic — it’s a revenue tool. You look organized, serious, and trustworthy. That’s how you justify $100+ diagnostic fees.
🌐 Web Dashboard
PRO is not an app upgrade. It’s cloud-backed infrastructure. View every vehicle, every session, every second-by-second chart from any browser. Generate and edit reports from your desk. Search your diagnostic history. Compare vehicles side by side. Capture in the field. Reason later at your leisure. That philosophy scales to fleets, multi-vehicle shops, and long diagnostic sessions.
💬 ARIA Web Chat with Memory
Talk to ARIA from any browser — not just the app. Start a conversation on your phone in the field, pick it up on your laptop at the desk. ARIA remembers every prior conversation about the vehicle: what was asked, what was answered, what you told it, what it already diagnosed. No repeating yourself. No lost context. Your entire diagnostic history with that vehicle is always at ARIA’s fingertips, layered on top of the real-time telemetry data. This is continuity no scan tool offers.
✍️ AI Report Editor
Generate reports from the web with a full markdown editor and live preview. Tell the AI to make changes — “add the customer’s complaint,” “emphasize the safety concern,” “rewrite the recommendation.” ARIA builds the narrative from your real diagnostic data. You edit and polish. The result is a professional report no scan tool printout can match.
🔍 Vehicle Intelligence
Go beyond the scan. PRO includes full vehicle intelligence — market value (trade-in, private party, dealer retail), title checks, auction history with photos and damage details, warranty status, maintenance schedules, common repairs, and sales history. Opt in per report and ARIA weaves the data into your diagnostic narrative. Know what the vehicle is worth. Know what it’s been through. Know what it needs.
♾️ Unlimited PDF Reports
No caps. No counting. Scan 10 cars a day, generate 10 reports. Every report is branded with your shop identity and backed by real telemetry data and AI analysis. Premium users get reports too — but PRO removes the limits because this is how you run a business, not a hobby.
Long, fat diagnostic sessions. Full telemetry. Second-by-second data streaming across every parameter the vehicle reports.
Then ARIA goes to work — AI reasoning, pattern spotting, cross-referencing historical sessions, building charts, telling a story. The mechanic doesn’t stare at numbers. ARIA tells you what you need to know.
That’s AI done right. Not a chatbot bolted onto a code reader. An agent that captures everything, reasons autonomously, and presents conclusions you can act on — and hand to a customer.
Everything in Premium, plus the professional toolkit:
Free shipping to the lower 48 U.S. states. International shipping available for a flat $14.99.
🔧 Mobile Mechanics
Show up with a wireless OBD-II interface and a phone. Leave with a branded diagnostic report the customer can hold. “Here’s what I found, here’s what it means, here’s what I recommend.” That report is why they pay you $100+ for the visit instead of Googling the code themselves.
🏪 Independent Shops
You’re competing against dealerships with $8,000 Snap-on rigs. OBDAI PRO gives you AI-powered diagnostics, professional documentation, and vehicle intelligence at a fraction of the cost. Your reports look better than their scan tool printouts.
🚗 Pre-Purchase Inspectors
Auction history. Title check. Market value. Full diagnostic telemetry. All woven into one branded report. Hand it to the buyer and they know exactly what they’re getting. That report pays for your entire annual PRO subscription on the first job.
🚙 Car Flippers
Know what you’re buying before you bid. Know what’s wrong before you price. Generate a clean diagnostic report for the buyer that builds trust and moves inventory faster. Three or four flips and PRO has paid for itself ten times over.
OBDAI is built by someone with 28 years in emissions testing and automotive diagnostics. Not a Silicon Valley team guessing what mechanics need. Someone who understands the workflows, the compliance headaches, the edge cases, and the technicians who deal with them every day. PRO is priced for seriousness — powerful capability at a fair price. No rent extraction. No legacy gouging. Just the right tool at the right cost.
Professional scan tools cost $300–$12,000 for hardware alone — then $129–$795/year for software subscriptions. Shop management SaaS runs $179–$300/month. CARFAX for shops is $300/month.
OBDAI PRO is a fraction of that. AI-powered diagnostics, branded reports, vehicle intelligence, and a web dashboard — all for less than one month of the software you’re probably already paying for. The GEN 2 scanner is included.

Some questions can’t be settled from a search snippet: which pin is which on a connector, what a sensor should read unplugged, or the factory test procedure for a code. For those, open Research a question in the OBDAI app, type your question with the year, make, model and engine, and confirm. ARIA searches, opens and reads factory and other primary service sources, then returns a cited report with what she found and where she found it. A job usually takes a few minutes.
Research works from the question you type. It does not read your recorded session on its own, so include the readings you want checked, such as a voltage, a fuel trim or a code.
A shop technician chasing a power-loss complaint on a 2015 Chevrolet Cruze 1.4T asked ARIA for the upstream O2 sensor connector pinout. Quick search only turned up parts-store snippets, so she wouldn’t guess which pin was which. With the sensor unplugged he saw 1.275 V and spent the night treating it as a shorted sensor. GM’s factory procedure puts the unplugged bias at 1.5 to 3.0 V, more than a generic O2 reading can display, so that reading was normal. With deep research, ARIA found GM’s factory test procedure, gave the connector cavities with their tests, explained the 1.275 V reading and flagged that a parts-store pinout had the signal pins reversed.
Your Pro plan includes 3 completed research jobs per month (Ultra includes 10). One job runs at a time per account. A job that fails or returns no cited report does not count. Research usually takes a few minutes and needs internet. Your normal ARIA questions and quick search keep their usual access. Source availability and applicability vary; research cannot guarantee a pinout, procedure or repair result.
You describe the problem; ARIA plans the readings, conditions and follow-ups. Check-ins and condition watches share one active-slot pool in any mixture.
| Allowance or capability | Premium | Pro | Ultra |
|---|---|---|---|
| Active watches and check-ins, combined | 2 | 5 | 10 |
| Optional automatic follow-ups per connected session | 8 | 20 | 40 |
| Optional automatic follow-ups per account/month | 100 | 300 | 600 |
| ARIA deep research: completed jobs per account/month | Not included | 3; one job at a time | 10; one job at a time |

| Supported Windows J2534 connection | Not included | Not included | One transferable Windows seat |
| Hardware in these GEN2 bundles | GEN2 | GEN2 | GEN2; J2534 interface, PC and tablet excluded |
Watches and check-ins require the app to remain open and connected. Cloud features require internet. Vehicle, ECU, adapter and sampling support determine the readings available; a slot is not a faster polling rate.

Real analysis from recorded vehicle sessions.
ARIA connects monitor results, operating conditions and parameter behavior.
Compare sessions and check the distance from the ECU’s reported limits.
Keep the analysis with the vehicle and share a clear report.
In this recorded example, ARIA compares 0.583 V with 0.132 V against a 0.050 V minimum. She explains the remaining margin and why a single monitor snapshot does not establish deterioration.
ARIA considers coolant temperature, load, manifold pressure, throttle and fuel trims together. The explanation ties the measurements to the vehicle’s operating state.
ARIA compares monitor trends with past fuel trims and drive-cycle context. In this example, she identifies a catalyst ratio worth watching while explaining that it remains below the failure threshold.
Continue the analysis with interactive ARIA Web Chat, choose the source session and turn the findings into an editable, shop-branded report with repair and maintenance context.
See the vehicle at the moment the fault set, then check the monitor evidence manufacturers use to judge component performance.
Selectable parameter graphs, six fixed dashboard gauges, emissions readiness and complete parameter coverage—presented as the actual product, not caption art.
The OBD BLE GEN2 adapter connects the vehicle to OBDAI and enables SAE J1979-2 support. It arrives protected in its own case.
Ask ARIA for connector pinouts, wiring tests, specifications or factory diagnostic procedures. She digs through factory and primary service sources and returns a cited report with a practical next test.
Give her the vehicle, your question and any readings you want checked, then approve the research in chat.

OBDAI Ultra on Windows
Autel, TOPDON, THINKCAR and MUCAR tablets make you drill down: make, model, year, system, module, data list. Then back out and do it again for the next module. Ultra puts ARIA on the J2534 VCI you already own, and you just ask.
Read it, back out, pick the next module, start over. Then figure out what it all means on your own.
"Aria, how many systems do you see on this Ford?"
One question. ARIA finds the modules, pulls the readings and tells you what matters.
Example: one real session on a 2017 Ford Explorer with a Bosch VCI. Your numbers depend on the vehicle and your interface.
ARIA sweeps the vehicle and comes back with 25 responding control modules, sorted by area: powertrain and battery, ABS and steering, airbags, body and doors, climate, seats, infotainment, cluster and parking aid.
She also tells you 14 more didn't answer, and that no answer doesn't mean a dead module. Some are options this truck doesn't have.
74 readings from all 25 modules in one answer. Brakes, doors, seats, liftgate, airbags, power steering, battery control, rear climate, radio. Three from every module, two from the gateway because that's all it exposes.
When three requests came back unavailable, she swapped in readable ones on her own. Nobody had to pick a single item from a list.
Every value ARIA pulls lands on the Following ARIA screen, labeled by module with a timestamp. Power steering key state, belt tension sensor, occupant weight, liftgate latch, rear blower, module voltages.
No black box. You watch the evidence come in, and it's saved with the session.
A scan tool hands you a wall of values and leaves you to guess. ARIA flags what needs context before anybody calls it a fault: an airbag occupant state of "Forbid", a radio reset counter at 255, a shift-type label that doesn't match the gear display.
That's the difference between data and a diagnosis.
Same 2017 Explorer, same questions. The Bluetooth GEN2 that ships with every Ultra sees 5 modules. Plug in a J2534 VCI and ARIA sees 25, then pulls readings from every one of them.
Modules and readings vary by vehicle, interface and supported systems. Device scenes are illustrations; every screen shown is a real OBDAI screen from a 2017 Ford Explorer session on November 4, 2026. Use your Windows J2534-compatible interface with its manufacturer's driver. The VCI and Windows PC are not included; the GEN2 wireless adapter is.
OBDAI Ultra works with Windows J2534-compatible interfaces. OBDAI implements the J2534 04.04 and 05.00 standards, so compatibility extends across manufacturers. Common interfaces include the devices below.

| Manufacturer-specific data | ARIA goes past the engine computer into modules like body control, brakes, airbags, power steering, parking aid, trailer brake, transfer case, climate, seats and EV battery. Available modules and readings vary by vehicle and adapter type. |
| OBD-II — J1979-1 & J1979-2 (OBDonUDS) | Check supported fault codes, live data, freeze frame, Mode 6 and readiness. Includes OBDonUDS through GEN2 or Windows J2534. |
| Keep the evidence together | Bring recorded standard OBD-II data into the diagnostic review. |
| Finish the customer work | Turn the session into a shop-branded repair estimate, diagnostic, emissions or pre-purchase report. |
| Work offline where supported | Windows diagnostics can work offline after activation. ARIA and cloud services require internet. |
| GEN2 is included too | The first-year bundle includes a shipped GEN2 adapter. |
Use a compatible Windows J2534 interface and its manufacturer’s driver. The VCI, Windows PC and manufacturer software or subscriptions are not included. Factory-information research runs on request in ARIA chat.
Emissions reports are pre-check documents, not official inspection certificates.
Every plan puts ARIA in charge of the scan tool: tell her the symptom, talk or send a photo, and let her choose readings, schedule check-ins and watch for changes. She reviews the recorded drive second by second and remembers the vehicle. Choose the tools you need to turn that evidence into your next step.
