AI-assisted OBD2 diagnostics
Real car data. Clear AI guidance. Built for the driveway.
Revzy reads live OBD2 signals and fault codes, then turns them into plain-language diagnostic guidance you can review before deciding what to do next.
Use the simulator for a no-car demo. Use Chrome or Edge for real USB/Bluetooth ELM327 adapters.

AI summary
The pattern suggests an EGR flow issue. Check vacuum lines, valve response, and related sensor readings before replacing parts.
Why it matters
Data first, AI second.
Revzy starts with decoded engineering-unit readings from the vehicle, not a generic symptom checklist. The AI report is useful because it has RPM, coolant, fuel trim, EGR, fault codes, and session context to reason from.
Open simulator scan →How it works
A practical workflow for owners who want to understand the car before buying parts.
Connect
Use simulator mode instantly, or connect a compatible ELM327 adapter in Chrome or Edge.
Scan
Watch live gauges, read fault codes, and capture decoded OBD2 signals.
Understand
Generate AI-assisted diagnostic guidance from the same vehicle data.
Live OBD2 dashboard
Monitor engine, fuel, EGR, temperature, and voltage readings in real time.
Fault-code workflow
Read codes and keep DTC clearing behind the existing pre-clear evidence flow.
AI report context
Use decoded signals and session context to produce clearer diagnostic explanations.
Simulator-first demo
Try the product safely without a vehicle or adapter before real hardware testing.
Safety boundary
Diagnostic guidance is not a substitute for safe repair judgment.
Revzy explains what the data suggests, but vehicle repair decisions still need safe inspection and qualified judgment. Do not test while driving. Do not clear fault codes unless you understand what evidence you are preserving.
