AI diagnostics for techs & serious DIYers
Diagnose faster. Fix it right the first time.
Describe the fault the way you'd tell a technician. Fixiom works the problem with you — real specs, real diagrams, recalls and TSBs — and tells you straight when it isn't sure. Plug in a Bluetooth OBD2 adapter and it reads the car live, too.

Less time chasing faultsOne directed next step at a time — not forum spelunking.

More jobs out the doorFrom symptom to a confirmed, documented fix.
Two ways to use it
Just your phone. Or plug in and read the car live.
Most of Fixiom needs no hardware at all. Add an adapter only when you want it to measure the car in real time.
Ask it anything
Symptoms, trouble codes, factory specs, fuse legends, wiring diagrams, recalls — even a photo of a part. It reasons it through and answers.
Read the car live
Pair any Bluetooth OBD2 adapter and Fixiom measures the vehicle itself — live data, codes off the car, freeze frames, and monitoring while you work.
It reasons from real data — and won't bluff.
When the data doesn't support a firm call, Fixiom says so and gives you the next test — instead of sending you after the wrong part. Fewer wrong-part orders. Fewer comebacks. Your call stays the final one.

A shop's worth of reference, reasoned on demand.
Everything here works with nothing but the phone in your hand.
Symptom → cause
Describe what the car's doing; Fixiom reasons it down to likely causes and what to check first.
Trouble codes explained
Paste a code and get the plain-English cause and the usual suspects — including manufacturer-specific meanings.
Specs, cross-checked
Oil, coolant, torque, capacities — cross-checked before they're stated, with a flagged range when sources disagree.
Fuse legends & diagrams
Pulls real fuse-box legends and wiring or component diagrams for the vehicle in front of you — never AI-drawn.
Recalls & TSBs
Checks NHTSA safety recalls and service bulletins for your exact year, make, and model — automatically.
Read a part from a photo
Snap a connector, a sensor, a worn component — Fixiom reasons over the picture with you.
With an OBD2 adapter
Plug in and it reads the car live.
Pair any Bluetooth adapter (~$20–30) and Fixiom stops guessing and starts measuring — watching the exact signals a fault needs and catching the moment it happens.
Why the answers hold up
Any AI will answer confidently. Fixiom earns it first.
A wrong answer costs you parts, hours, and comebacks — so Fixiom is engineered to verify before it speaks, and to say so when it can't.
Specs are cross-checked before they're stated
Every number — capacities, torque values, fluids — is checked against live sources and attributed to your exact engine and generation. When sources agree, you get the number. When they don't, you get the honest range. When it can't verify, it says so and points to the OEM source.
No single-source guess dressed up as a fact.
Diagrams are real documents
Fuse legends and wiring diagrams are retrieved originals, verified for your generation. If the right-year document can't be verified, you get a search lead instead of a look-alike.
Fixiom never draws a diagram with AI — a plausible-looking fake fuse map is worse than none.
Bulletins come from the source
TSBs and recalls are looked up in NHTSA's own data for your exact year, make, and model — on the server, every vehicle question, automatically.
Never recalled from AI memory — it can't cite a bulletin that doesn't exist.
Honest about the hardware ceiling
Generic OBD2 reads engine-side data on any 1996+ vehicle — and no generic adapter can pull factory-locked ABS/airbag codes or run bidirectional tests. Fixiom tells you where the ceiling is and what tool the job actually needs.
When it can't measure something, it says so — instead of pretending.
How it works
Ask. Diagnose. Fix.
Ask it
Describe the symptom the way you'd tell a technician, paste a code, snap a photo, or just talk — no account, no setup.
Work it
Fixiom reasons from real data to likely causes — one directed next step at a time, evidence for and against, honest confidence.
Go live Optional
Plug in a Bluetooth OBD2 adapter and it measures the car itself — and watches live data for the exact moment a fault shows.
Good to know
Questions techs ask first.
Do I need an OBD2 adapter?+
No. On your phone alone, Fixiom handles symptoms, trouble codes, factory specs, fuse legends, wiring diagrams, recalls, even a photo of a part. Add any Bluetooth OBD2 adapter (~$20–30) and it also reads the car live — codes, live data, freeze frames, readiness, Mode 06.
Does it just make things up like other AI?+
That failure mode is exactly what Fixiom is built against. Specs are cross-checked against live sources before they're stated; diagrams are retrieved real documents, never AI-generated; recalls and TSBs come from NHTSA data, not AI memory. When it can't verify something, it tells you — and gives you the next test instead of a guess.
Do I need an account?+
No account, no email — ever. The app works the moment it's installed. Purchases go through the App Store or Google Play.
Which adapters work?+
Any standard ELM327 Bluetooth adapter. Bluetooth LE works on iPhone and Android; classic Bluetooth works on Android. Don't have one? The app includes a plain-English buying guide.
Which vehicles does it cover?+
The AI side helps with almost anything on wheels. Live scanning works on OBD2 vehicles — 1996 and newer in the US. Coverage of extra signals (like ABS/chassis data) varies by model, and the app is upfront about what your vehicle supports.
Does it replace a factory scan tool?+
It reads everything generic OBD2 exposes and reasons on top of it. It won't actuate components, reprogram modules, or read factory-locked body codes — and it tells you where its coverage ends. Think diagnostic thinking alongside your existing tools.
What does it cost?+
