# DiagnoseMycar — Full Reference

> DiagnoseMycar is a free, AI-powered vehicle diagnostic tool. Users describe a car problem in plain language, optionally upload photos, audio, or video, and receive a complete diagnostic report in under 30 seconds. No mechanic visit, no sign-up, no app download required.

## Overview

DiagnoseMycar is designed for car owners who want to understand what is wrong with their vehicle before visiting a mechanic. The tool:

- Analyzes text descriptions of vehicle symptoms
- Accepts photo uploads (e.g. dashboard warning lights, visible damage, leaks)
- Accepts audio uploads of unusual sounds (e.g. engine knocking, brake squealing) — the AI transcribes and analyzes the audio
- Accepts short video uploads showing the problem in action
- Generates a detailed AI diagnostic report including possible causes, severity, cost estimate, and next steps
- Allows unlimited follow-up questions to the AI mechanic after the report is unlocked

## How the Diagnosis Works (Step by Step)

**Step 1 — Vehicle Details (optional)**
The user enters their vehicle's year, make, and model. This is optional but improves accuracy by allowing the AI to account for known issues, recalls, and common failures specific to that vehicle.

**Step 2 — Problem Description (required)**
The user describes the problem in plain language. The more specific the description — when the problem occurs, what it sounds or feels like, how long it has been happening — the more accurate the diagnosis.

**Step 3 — Media Uploads (all optional)**
- Photos: dashboard warning lights, visible damage, leaks, worn components
- Audio: a recording of engine knocking, brakes squealing, rattling, or any unusual sound. The AI transcribes the audio and incorporates it into the analysis.
- Video: a short clip showing the issue (stalling, vibration, smoke, etc.)

After submission, the AI analyzes all inputs and generates the report. The user enters their email address to unlock the full report.
