AI car diagnosis that doesn't guess
Tell WrenchPulse what your vehicle is doing — a noise, a warning light, a behavior — and get a structured diagnosis with the most likely causes, the tests to run, and the safety risks to watch for.
Who it's for
- Car owners who want to understand a problem before paying a shop
- DIY mechanics who want a second opinion before swapping parts
- Small independent garages handling unfamiliar makes
Why it matters
- Most check-engine codes have several possible causes — random part swaps cost hundreds
- Forum threads are inconsistent and rarely vehicle-specific
- Some symptoms point to safety-critical systems and need professional attention immediately
How it helps
Structured output, not a chatbot
Every diagnosis follows the same 11-block format: symptoms, likely causes, tests, parts, time, cost, safety, and escalation.
Vehicle-aware
Answers reflect your year/make/model, mileage, and recent repairs — not generic advice.
Safety-first
Anything involving brakes, steering, fuel, or airbags is escalated to a professional. No reckless DIY suggestions.
Saves the work
Every session is saved so you can compare results, share with a mechanic, or revisit later.
Run your first diagnosis
No credit card. 1 vehicle and 3 diagnostic sessions on the free tier.
