Free tier analyses the first 30 seconds of any clip. AI diagnosis isn't always 100% accurate — treat it as a starting point, not a final answer. For brakes, steering, or fuel issues, stop driving and see a mechanic regardless of what this says.
Ticking Noise
A light, rapid tap-tap-tap — often from lifters, injectors, or valvetrain.
Diagnose this →Knocking Noise
A deeper, heavier knock — can be fuel-related or a more serious bearing issue.
Diagnose this →Rattling Noise
A loose, metallic rattle — often a mount, heat shield, or timing component.
Diagnose this →Not sure which one matches? The recorder above handles any engine sound — you don't have to pick a category first.
An experienced mechanic can often tell what's wrong with a car before they even open the bonnet, just from the engine sound. This tool does the same thing with AI: record or upload a clip of the noise your car is making, and it analyses the acoustic pattern against thousands of known fault signatures to tell you the likely cause.
It works for any unusual car engine sound — not just the three symptoms above. Whining, squealing, grinding, humming, clicking — if you can record it, the AI can attempt a diagnosis. Add a short text description and your vehicle's brand, model, and year for a more precise result.
Engine noise rarely appears out of nowhere. A new tick, knock, or rattle is almost always a sign that something has changed — a component wearing down, a fluid running low, or a part working loose. Some engine sounds are harmless and just need monitoring; others mean you should stop driving immediately. The tricky part is telling the difference without specialist knowledge, which is exactly the gap this tool is built to close.
Recording the sound and getting an early read on it costs you nothing and takes under a minute — often far cheaper than waiting until a minor issue becomes an expensive one.
Searching a symptom online usually turns up a long, generic list of everything that could theoretically cause a noise — useful for background reading, not so useful for figuring out what's actually happening with your specific car. This tool takes the opposite approach: it listens to the actual sound your engine is making, plus any details you add about your vehicle, and narrows that long list down to a ranked, specific answer rather than leaving you to guess which of ten possible causes applies to you.
That said, it's not a replacement for a hands-on inspection — think of it as the fast, free first step that tells you how urgent the issue is and what to check or ask about next, before you spend time or money acting on a guess.
A tool that listens to a recording of your engine noise and identifies the likely cause using AI — the same way a mechanic diagnoses by ear before opening the bonnet.
Ticking, knocking, rattling, squealing, grinding, whining, and most other unusual sounds. If you can record it, the AI can attempt a diagnosis.
The free tier analyses the first 30 seconds of any clip — normally enough for a clear diagnosis.
No — it's a strong starting point, not a final answer. It can miss things a hands-on inspection would catch. Stop driving immediately for brake, steering, or fuel issues regardless of what it says.
Yes, free with no login. Longer recordings beyond 30 seconds are planned as a future paid option.
