What WrenchPulse is
WrenchPulse is a web application that uses AI to help vehicle owners understand what is wrong with a car or light truck before spending money on parts. The user describes symptoms or enters OBD2 diagnostic trouble codes; WrenchPulse responds with likely causes ordered by probability, safe checks the user can perform, and a clear signal when the problem should go to a professional.
Who it is for
- Everyday car owners who want to understand a check engine light.
- DIY beginners who need step-by-step, safety-first guidance.
- Light mechanics and small garages tracking repairs across several vehicles.
Features
- AI diagnostic sessions — guided question-and-answer flow that narrows the cause of a symptom.
- OBD2 helper — explains diagnostic trouble codes in plain language, including what a code does not prove.
- Copilot chat — follow-up questions about an ongoing diagnosis or repair.
- Part identification — upload a photo of a component to identify it.
- Maintenance tracking — service intervals and records per vehicle.
- Repair log — history of what was replaced, when, and at what cost.
- Community cases — public repair cases other owners have documented.
- Editorial guides — OBD2 code explainers, symptom guides, used-car reliability guides and scanner comparisons.

- When available data is insufficient, it says so instead of guessing at a part.
