RevvAI: Car Sound Scanner

Record a strange car sound and get an AI-powered diagnosis in seconds. Understand the likely cause, urgency level, affected area, and what to do next.

A strange knock, squeal, rattle, or hum can be difficult to explain — especially when you are not sure whether it is harmless or requires immediate attention.

RevvAI: Car Sound Scanner analyzes sounds from your vehicle and helps identify their likely source. Record the engine, brakes, suspension, transmission, or another area to receive a clear result in seconds.

Understand unusual car sounds

• Record sounds from 5 to 60 seconds • Select when and how the sound appears • View a live audio waveform while recording • Receive up to three possible causes • See the affected vehicle area • Check how urgently the issue should be inspected

Clear diagnostic results

Each analysis provides practical information without complicated mechanical terminology:

• Likely cause of the sound • Engine, suspension, brakes, transmission, exhaust, or another area • Critical, check soon, or low urgency status • Simple explanation of the possible issue • Recommended next steps • Estimated repair cost range • Quick access to nearby repair services

Better recordings, more useful results

RevvAI guides you through the recording process and helps detect excessive background noise, wind, music, or poor sound quality. Recording tips help you capture a clearer sample close to the suspected source.

Check a used car before buying

Follow a guided sound inspection for different vehicle areas, including:

• Engine at idle • Engine during acceleration • Suspension movement • Braking sounds • Multiple recordings from different zones

Review the results together to identify sounds that may deserve closer inspection before purchasing a vehicle.

Keep your diagnostics organized

• Save recordings and results • Reopen previous analyses • Add vehicle make, model, year, and mileage • Organize diagnostics by vehicle • Compare recurring sounds over time • Export results for further inspection

Whether you hear an unfamiliar engine noise, notice a sound while braking, or want additional information before visiting a mechanic, RevvAI helps you understand what your car may be trying to tell you.
