AI Mechanic

The problems that quietly add up.

Your AI Mechanic keeps an eye on your garage and speaks up before a small issue becomes an expensive one — when a repair doesn't hold, or when your fuel economy starts slipping. Not a chatbot. Just an early warning when something deserves a second look.

How OBD2 reading works on MyDIYGarage

Reading codes straight from your car runs in the MyDIYGarage mobile app over Bluetooth OBD2. Logging fault codes, descriptions, your diagnosis, and the full history works everywhere — web, tablet, or phone.

Native iOS and Android apps are coming soon. Today the mobile experience installs as a PWA from your browser; the App Store and Play Store builds are next.

It notices, so you don't have to.

When a repair doesn't hold or your fuel economy slips, the AI Mechanic puts it on your dashboard — in plain language, with one tap to act.

A second set of eyes on your whole garage.

The early warnings that matter most are the ones spread across months — exactly the ones a person forgets to look for.

A "fixed" problem that isn't

The problem: You cleared a code months ago and moved on. When it returns, you start the diagnosis over from scratch.

How MDG helps: The AI Mechanic recognizes the code is back and surfaces it with the history attached — so you pick up where you left off, not from zero.

Money leaking at the pump

The problem: A few percent off your mileage is invisible tank to tank — but over months it's real money, and it's often a fixable maintenance item you didn't know to check.

How MDG helps: The AI Mechanic compares your fuel economy to your vehicle's own baseline and only speaks up when there's a real, sustained drop — turning a slow, silent decline into a clear heads-up.

From alert to action in one tap

The problem: Knowing a problem is back doesn't help if it falls off your list before you do anything about it.

How MDG helps: Tap Add to Service Log and it creates a scheduled inspection on the right vehicle and opens it, ready for you to add detail and save.

Proactive by design — not another thing to ask

Two early warnings, drawn from your own garage

Most "smart" car tools wait for you to ask a question. The AI Mechanic works the other way around: it looks at the records already in your garage and tells you what you didn't know to look for. Today it gives you two early warnings.

A repair that didn't hold. When a fault code you'd already marked resolved shows up again on the same vehicle, that's a louder signal than the first time — the original repair may not have fully addressed the cause. By the time it reappears the fix is often weeks or months in the past, easy to forget; the AI Mechanic remembers and connects the two, with the history attached, so you pick up where you left off instead of from scratch.

Fuel economy that's slipping. When your gas mileage drops well below what's normal for your vehicle and stays down across recent fill-ups, it's often an early sign of something routine — low tire pressure, a tired air filter, worn spark plugs, or a lazy oxygen sensor. The AI Mechanic measures each fill-up against your own history and gives you a heads-up before it quietly costs you at the pump.

A heads-up, then a one-tap next step

When a recurrence is detected, an insight card appears on your dashboard, written in plain language — no codes-only wall, no jargon. It tells you which code came back and on which vehicle, so the situation is clear at a glance.

From there, a single tap on Add to Service Log turns the heads-up into a plan: MyDIYGarage creates a scheduled inspection for that exact vehicle and drops you straight onto the new service-log entry, already open in edit view. Add anything else you know — symptoms, a shop appointment, parts to check — and save. Nothing is recorded until you confirm, so the AI Mechanic suggests, and you decide.

It builds on the history you already keep

The AI Mechanic isn't a separate database or a new habit to maintain. It runs on top of the records you already keep per vehicle — your fault-code history and your fuel logs. The more history you keep, the sharper its early warnings become, because every one is measured against what actually happened on your car, not a generic average.

Everything stays per vehicle and private to your account. These two early warnings are where the AI Mechanic starts — and more are on the way.

Questions, answered.

Is the AI Mechanic free?
The AI Mechanic is free for a limited time, on every account — there's nothing to enable and no credit card required. It's a launch promotion, so it won't be free forever, but we'll give plenty of notice before that changes. MyDIYGarage itself is always free to start on your first vehicle.
Is the AI Mechanic a chatbot?
No. There's no chat box and nothing to type. The AI Mechanic works proactively — it watches your vehicles in the background and surfaces an insight on your dashboard only when something's worth your attention, like a fault code that's come back or fuel economy that's slipping.
What does the AI Mechanic watch for right now?
Two things today: fault codes that come back after you fixed them, and a sustained drop in your fuel economy versus your vehicle's own normal. Both are drawn from the history already in your garage — and more early warnings are on the way.
Where do the insights come from?
From your own records — your fault-code history and your fuel logs, per vehicle and private to your account. The AI Mechanic measures each vehicle against itself, not a generic average, so the heads-up fits your car. It doesn't need any new information from you.
What happens when I tap "Add to Service Log"?
It creates a scheduled inspection on the correct vehicle's service log and takes you straight to that entry, open and ready, so you can add anything else you know before you save. You stay in control — nothing is logged until you confirm.
