Your check-engine light just came on. Is it safe to keep driving — or should you stop? Cavox gives you a plain-language read in minutes, right in your car, without a $80–300 dealer visit.
Most code readers just show you "P0301" and leave you Googling. Cavox reads the fault, then hands you an AI-written verdict in human language — what it is, likely causes, what to check first, and how urgent it is — so you can make the call yourself.
WHAT YOU GET
• A plain-language verdict — "Looks OK to drive", "Worth a look", or "There's a problem" — never just a raw code.
• AI explanations — every trouble code decoded into what it means and what to do next.
• Live monitoring — real sensor readings (RPM, coolant temp, battery, engine load and more), with AI that flags anomalies even when there's no code but the car "feels off".
• Your car's history — every scan saved and searchable, so you can see what changed and when.
• A garage for several cars — each with its own history. Histories are never merged.
• Easy VIN — read it straight from the adapter or scan it from your documents. No typing, no typos.
• Demo mode — walk through the whole app on a sample car before you even own an adapter.
WORKS WITH YOUR ADAPTER
Cavox connects over Bluetooth to a standard OBD-II / ELM327 adapter — the common kind you may already own. No proprietary hardware, no locked ecosystem.
HONEST BY DESIGN
Cavox never fakes an "all clear". When a reading isn't certain, it tells you and points you to a mechanic instead of guessing. The core verdict is free; Premium unlocks full AI diagnosis, live monitoring and saved history.
Safety: always stop your vehicle before running diagnostics. Do not use while driving.
Cavox is a diagnostic aid, not a substitute for a professional inspection. It does not guarantee your vehicle is safe — always consult a qualified mechanic before making repair decisions.
