The AI mechanic for DIYers & working techs
Know what's wrong before you spend a dime on parts.
Describe the problem the way you'd tell a mechanic and Fixiom works it with you — cross-checked specs, real diagrams, recalls and TSBs. Plug in a Bluetooth LE adapter ($20–30) and it stops reasoning about cars in general and starts reading yours: live sensor data, watched while the fault happens. Nothing else in the category does that.

Talk to Fixiom
Hold the button. Say it. Hands stay on the wrench.
Hold the F button on the home screen — or any mic — and just say it. Commands run on the spot, questions go to the AI, and the answer comes back out loud in a natural voice. Your first spoken answer is on the house; Hobbyist and Pro keep the voice on.
How far it goes
Starts on your phone. Gets sharper with an adapter.
Most of Fixiom needs no hardware at all. Plug one in and the same diagnosis stops reasoning about cars in general and starts measuring yours.
Ask it anything
Symptoms, trouble codes, factory specs, fuse-box and wiring diagrams, recalls — even a photo of a part. It reasons it through and answers.
Read the car live
Pair a compatible 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 parts. No doing the job twice. Your call stays the final one.
For context: a diagnostic at an independent US shop typically runs $131–209, per published industry averages from RepairPal. Ask Fixiom first.
Ask it your first question — freeOn your phone
Everything a good mechanic keeps in their head — on demand.
Fixiom opens to a home screen for your vehicle — code lookup, recalls & bulletins, diagrams, live monitoring, and the scan tool each one tap away, with the AI behind all of it. 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.
Code lookup
Type any check-engine code — or scan it off the car — and get the plain-English cause and the usual suspects, free. Manufacturer-specific meanings included.
Specs, cross-checked
Oil, coolant, torque, capacities — cross-checked before they're stated, with a flagged range when sources disagree. Wheel-end torque — axle nut, hub, lug — comes straight from SKF's published torque guide: a verified number with a source, not a web consensus.
Fuse boxes & diagrams
Pulls real fuse-box and component diagrams for the vehicle in front of you — never AI-drawn — plus a search lead when you need a wiring diagram.
Recalls & Bulletins
Your vehicle's NHTSA safety recalls and service bulletins, checked live — browsable and searchable from the home screen, and checked automatically during a diagnosis.
Read a part from a photo
Snap a connector, a sensor, a worn component — Fixiom reasons over the picture with you.
Talk to Fixiom
Hold the F button and just say it — “pull my codes”, “test my battery”, or any question — and hear the answer back in a natural voice. Your first spoken answer is on the house.
With an OBD2 adapter
Plug in and it reads the car live.
Pair a compatible 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
Fewer wrong parts. That's what verifying first actually buys you.
A wrong answer costs you parts, hours, and doing the job twice — 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. Wheel-end torque specs — axle nut, hub, lug — are answered from SKF's published torque guide, matched to your exact year and model.
No single-source guess dressed up as a fact.
Diagrams are real documents
Fuse-box and component diagrams are retrieved originals, verified for your generation. If the right-year document can't be verified — or when you need a wiring diagram — 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 Fixiom's all-module scan reaches further — ABS, airbag and body-module codes on vehicles that speak the modern UDS protocol. Fixiom itself is read-only by design — it never runs bidirectional tests or actuations — and plenty of older modules answer only factory tools. 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
The questions everyone asks first.
Do I need an OBD2 adapter?+
No. On your phone alone, Fixiom handles symptoms, trouble codes, factory specs, fuse-box and wiring diagrams, recalls, even a photo of a part. Add a compatible Bluetooth OBD2 adapter (~$20–30) and it also reads the car live — codes, live data, freeze frames, emissions readiness and self-tests.
What does it cost?+
Free to download. The scan tool is free forever — read and clear codes, live data, freeze frames, emissions checks, the battery test, and the trip computer. Credits only cover the AI reasoning on top: 25 free AI credits to start — then one-time credit packs or plans from $11.99/month when you need more. Full pricing →
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?+
Most standard ELM327 Bluetooth adapters — the common ~$25 kind. Bluetooth LE works on iPhone and Android; classic Bluetooth works on Android. Avoid store-shelf units locked to their own app (FIXD, BlueDriver and similar) — the adapter buying guide has the full honest list.
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 — plus chassis and body-module codes on newer vehicles through the all-module scan — and reasons on top of it. It won't actuate components, program keys, or reprogram anything, and it tells you where its coverage ends. Think of it as diagnostic thinking alongside whatever tools you have.
