Carithm cross-references a vehicle's sound recording against its OBD-II fault code — narrowing down mechanical issues faster than either signal gives you alone. Built for teams triaging more than one car a day, anywhere in the world.
Record or upload the sound, add an OBD-II code if you have one, and get a ranked read on likely causes.
Not a consumer app — a triage tool for teams handling more than one vehicle at a time.
Drivers or dispatch record a noise the moment it's noticed. No app rollout — it runs in the browser they already have.
Give advisors a quick starting point on a noise complaint before committing a bay and a technician's hour to it.
Check trade-ins and incoming inventory for developing mechanical noise before a car goes on the lot.
Spot developing issues on high-turnover vehicles before the next customer does.
Each signal covers a different blind spot. Together, they narrow the range faster.
Three steps, done from a phone or a service desk.
Capture the noise close to its source. Add an OBD-II code too, if one's available — it's optional but sharpens the read.
The recording is compared against known mechanical sound patterns, alongside the code if one was provided.
Likely causes, an urgency read, and what to check first — before shop time gets committed to it.
Yes. Since it runs in any browser with no installation, dispatch staff, drivers, or technicians at any location can record and submit a sound the same way — wherever your operation is based.
It narrows the range of likely causes. Many mechanical noises — worn belts, bearing wear, suspension knock — never trigger a fault code, so sound alone often has to do the work. When a code is available, cross-referencing it against the sound gives a tighter, more specific read than either signal on its own.
No. The diagnoser runs directly in a browser on any phone, tablet, or desktop — nothing to install or roll out across a team.
The underlying tool works for either, but this page and workflow are set up for teams — fleets, workshops, dealerships, and rental operators — who are triaging noise complaints across more than one vehicle.
It's built around mainstream makes and models used worldwide. If you run a specific fleet mix and want to check fit before rolling it out, reach out and we'll take a look.
The diagnoser is currently free to use. If you're looking at consistent, higher-volume use across a fleet or multiple branches, contact us directly and we'll talk through what that looks like.
