A man posted on TikTok asking if other mechanics are using online resources to save time.

On Jan. 26, a man (@leninfavrico) asked about the digital tools used by mechanics in a video he posted on TikTok.

“Why do I feel like most mechanics use YouTube, or ChatGPT their way into a job?” he asks. 

“Whether it’s changing up oil pressure sensors or whatever it is, something complicated, they YouTube their way in,” he speculates. 

He mentions that this makes him feel like he should just learn to make the repairs himself: “I’m not mad about it, but I do feel some type of way because I’m basically being lazy because I can do my own research and do it myself.”

He then speculates that there must be an app that makes the process easier for mechanics. “But I feel like they have an app where it tells them what tool to use, it tells them exactly where it’s located, or something like that,” he says.

Do Mechanics Use Digital Resources Like YouTube Or AI?

Many mechanics do use YouTube, AI tools, and digital databases, as can be seen in this Reddit thread with mechanics discussing the very topic.

Modern auto repair is far more information-dense than it was even 15 years ago. Vehicles now come with complex electronics, software-controlled systems, and model-specific quirks that even experienced technicians can’t reasonably memorize. 

Watching a YouTube walk-through for a specific vehicle or problem is often faster than trial and error, especially for uncommon repairs or newly released models. Trade publications and training programs have long encouraged technicians to consult reference materials rather than rely on memory alone, as accuracy and safety matter more than pride.

AI can help explain fault codes, outline diagnostic steps, or summarize service procedures, but it can’t always replace manufacturer-approved repair data or hands-on diagnostics. A Reddit thread on the topic even shows that many shops restrict AI use to background research, since incorrect information could create liability issues.

Do Mechanics Use Apps To Guide The Repair Process?

Some apps do almost exactly what the TikTok creator described. Professional mechanics commonly use platforms like ALLDATA, which provide step-by-step repair procedures, factory service manuals, wiring diagrams, torque specs, and recommended tools based on the vehicle’s VIN. 

Automakers themselves also offer proprietary service software to licensed repair facilities. These tools aren’t considered shortcuts, but are industry-standard references designed to reduce mistakes, save time, and ensure repairs meet manufacturer specifications.
