Dr Underhood Live Assist

Stop guessing what's wrong with your car. Stop paying $150 just to "have it looked at."

Dr. Underhood Live Assist gives you two ways to get a real diagnosis — fast and on your terms.

PICK YOUR TIER

$20 — BASIC AI DIAGNOSIS
Powered by the Wrench Brain — thousands of real cases from a working mechanic's shop. Snap a photo or video, describe the symptoms, answer a few questions. Get a written diagnosis report you can take to ANY shop. No appointment. No bay fee. No upsell. The AI does the work; the case data behind it is real, not made up.

$99 — ADVANCED + LIVE
Everything in Basic, plus a live video session with Doc or a vetted master mechanic. Point your camera at the problem. Get answers in real time. Walk away with the same written report — but with the human in the loop.

HOW IT WORKS
1. Open the app, tell us your vehicle
2. Pick your tier — $20 AI, or $99 with the live call
3. Snap photos, send video, or hop on the live session
4. Get your diagnosis report by email

WHO THIS IS FOR
- You hear a noise and don't know if it's serious
- Your check-engine light is on and you want a real answer before a shop quotes you
- You're a DIY mechanic stuck on a job
- You're traveling and your car is acting up
- You don't trust the shop that's quoting you $3,000

WHAT YOU GET
- AI-powered diagnostic backed by a real mechanic's case data
- Written diagnosis report sent to your email
- Plain-English explanation of what's wrong, how urgent it is, and what a fair repair price looks like
- Optional live video upgrade when you want a human in the chair

SPECIALTIES
- GM AFM/DOD lifter diagnostics (5.3L and 6.2L V8 trucks and SUVs)
- LS/LT cam-related ticks and misfires
- Check Engine Light diagnostics on any make or model
- Drivability issues — stalling, hesitation, rough idle
- Strange noises — knocks, ticks, grinds, squeals
- Pre-purchase inspections, done over video

WHY THE PRICE
The local shop charges $150 to $200 for a "diagnostic fee" before they'll even tell you what's wrong. We charge $20 because the AI does 60% of the work using real shop case data. The live upgrade is $99 — still far less than what a shop charges for the same answer.

WHO'S BEHIND IT
Dr. Underhood Automotive — independent shop in Fort Smith, Arkansas. Owner Robert "Doc" Holmes has been turning wrenches for two decades. AFM and DOD lifter specialist. HP Tuners certified.
