Your car, explained. Carnivo is an OBD2 car scanner and AI car assistant that tells you what's going on with your car in plain language, whether it's the check engine light, another warning light, a fault code or a strange noise: what happened, how serious it is, whether you can drive, and what to do next. Buying a used car? Carnivo's pre-purchase inspection checks it with you before you pay.

OBD2 SCANNER FOR EVERYDAY DRIVERS
Plug in a Bluetooth or Wi-Fi ELM327 OBD2 adapter, tap Scan, and Carnivo reads your car's diagnostic trouble codes (DTCs). It checks the engine and, where your car answers, other control units such as ABS, airbags and body electronics. Systems it couldn't read are labelled unchecked, so an empty list never pretends to be "all clear".

CAR DIAGNOSTICS IN PLAIN LANGUAGE
Every fault code comes with a clear explanation from a built-in, offline code database. For each finding Carnivo shows:
• What happened
• How serious it is
• Can I drive?
• What to do next
While it scans, you see live readings such as RPM, coolant temperature, engine load and battery voltage. Freeze-frame data (the readings when the fault was stored, including fuel trim) is one tap away.

USED CAR INSPECTION BEFORE YOU BUY
A step-by-step pre-purchase inspection you do yourself, at the seller's:
• Guided photos of every angle, the tyres, the engine bay, the inside and the boot floor, plus close-ups of the spots where past repairs show
• The engine's sound, recorded on your phone
• A guided test drive
• The papers: does the VIN on the car match the registration, and is there a service history?
With an OBD2 adapter, Carnivo also reads the fault codes, checks for new ones during the test drive, compares the mileage you were given with the odometer readings stored in the car's control units, and flags codes that were cleared recently. The purchase report lists what it found, how much it matters and what to ask the seller, and exports as a PDF. Steps you skipped are named as unchecked, never as fine. Each report uses AI credits, shown before you create it.

CLEAR WARNING LIGHTS — HONESTLY
Carnivo can clear stored codes and turn the check engine light off, but it tells you first: clearing doesn't fix the fault, the light comes back if the problem is still there, and emissions readiness checks reset. The codes stay in your history as evidence.

AI CAR ASSISTANT
Ask about a warning light, a strange noise or a smell. Type it, record a voice note or the noise itself, send up to four photos or a short video. The assistant knows your car, its mileage and its latest scan, and helps you decide what to check and what to tell the mechanic. Your first AI questions are free; more AI credits come in one-time packs, no subscription. AI guidance is clearly marked and does not replace a qualified mechanic.

NO OBD2 ADAPTER? START ANYWAY
Add your car by VIN and use the AI assistant, maintenance log and service reminders straight away. Fault codes need an adapter, and Carnivo tells you that before you choose.

MAINTENANCE LOG AND SERVICE REMINDERS
• Record oil changes, brakes, tyres, repairs and notes for each car
• Service reminders by mileage or date, whichever comes first
• Keep every scan and cleared code as part of the car's history
• Manage several cars in one place

WORKS WITH
• ELM327-compatible OBD2 adapters over Bluetooth or Wi-Fi
• Cars with an OBD2 / EOBD diagnostic port, usually under the steering wheel. Which control units respond and which codes they report depend on the car.
