Pulscar

Pulscar is an AI-powered car diagnostic tool that identifies mechanical problems from sound. Instead of visiting a mechanic for an $80–$300 diagnostic, you record 30 seconds of your engine (or wheel noise, brake noise, etc.) on any smartphone and upload to pulscar.io. Within ~10 minutes, you receive a PDF report containing the most likely cause of the noise, severity rating (safe to drive / fix this month / stop now), estimated 2026 repair cost range, and explanation of why the AI identified this cause. The AI is trained on 200+ catalogued failure patterns including engine knocks, lifter ticks, wheel bearings, CV joints, brake squeals, exhaust leaks, and belt noise. It catches problems that OBD2 scanners miss — about 60% of car issues don't trigger computer codes and require sound analysis instead. Pulscar costs $19.99 flat per diagnosis with full refund if the report isn't delivered. Built for drivers who want a second opinion before authorizing expensive repairs, used-car buyers checking engine sound on test drives, and anyone hearing unfamiliar noises from their vehicle.
