Know what’s wrong with your car — before you get charged.
WrenchLogic learns from real-world faults, across real vehicles, and gets smarter every time someone uses it.

WrenchLogic isn’t just for mechanics.
It’s for people who own vehicles.
Mechanics are contributors, validators, and custodians of the knowledge — but the beneficiary is the public.
What WrenchLogic really is.
WrenchLogic exists because most people rely on a machine every day that they don’t understand, but are completely dependent on.
For most Kiwis & Australians a vehicle isn’t a luxury — it’s how they get to work, take their kids to school, access healthcare, and live their lives. Yet when something goes wrong, they’re forced to hand over trust blindly. They don’t know what’s wrong, what parts are involved, what’s urgent, what’s safe, or what’s fair.
That imbalance is where people get taken advantage off ( ripped off )
WrenchLogic was created to close that gap.
WrenchLogic doesn’t tell people how to repair a car.
It doesn’t replace mechanics.
What WrenchLogic does,
What it does is translate mechanical experience into understandable logic.
By guiding a vehicle owner through simple yes/no questions — the same questions an experienced mechanic asks in their head — WrenchLogic narrows a problem down to likely fault areas, the parts involved, and the systems affected.
It gives the owner:
context
language
confidence
and an understanding of what they’re dealing with
Not certainty — clarity.
When a vehicle owner understands:
whether a problem is brake-related or suspension-related
whether it’s urgent or something that can wait
whether it’s likely a sensor, a wear item, or a mechanical failure
They walk into a workshop differently.
They ask better questions.
They understand estimates.
They can spot when something doesn’t add up.
That alone changes the entire dynamic.
The bigger picture
We license people to operate multi-tonne machines at highway speeds, yet we don’t require them to understand:
how brakes actually work
what a worn tyre looks like
what wheel bearings sound like
what overheating really means
why fuel, temperature, and lubrication matter
WrenchLogic isn’t trying to turn owners into mechanics.
It’s trying to make them mechanically literate.
Just enough to be safe.
Just enough to be informed.
Just enough to not be taken advantage of.
Where mechanics fit in
Mechanics are not the target audience — they are the source of truth.
Their lived experience:
common failures
recurring patterns
real-world symptoms
what fails silently vs catastrophically
That knowledge is captured, reviewed, and structured so it can be shared responsibly with the public.
WrenchLogic doesn’t dilute the trade.
It preserves it.
WrenchLogic exists because vehicle ownership shouldn’t require blind trust.
People deserve to understand the machines they depend on — not to fix them, but to protect themselves, their families, and their finances.
That’s where experience becomes logic.
WrenchLogic is currently under development.
A mechanic-built diagnostic system app for your phone designed to isolate faults through structured questioning and probability.
