Maintenance, mileage, registration and recalls in one place — plus an AI mechanic that knows your exact vehicle, and quote requests sent to nearby shops on your behalf.
Most car apps do one thing. KarHub is the one that remembers everything and actually does something with it.
Add your VIN once. KarHub decodes your exact year, make, model, trim and engine, and every answer it gives from then on is about your car specifically.
Log oil changes, brakes, tires — anything. Date, mileage, cost and notes, kept in one timeline instead of a glovebox full of receipts.
Oil change due dates calculated from your actual driving, not a guess. Registration renewals and monthly odometer prompts too.
Checked against NHTSA's live database for your vehicle. Recalls are free to fix and easy to miss entirely.
Find shops around you with addresses, distance and directions.
A step-by-step penny test, with what each result actually means and when replacement stops being optional.
Ask anything about your car. Otto can see your service history and mileage, searches the web for real specifications rather than guessing, and cites where the answer came from. Send a photo of a warning light or a leak and ask about that.
Pick a job and how many shops to ask. KarHub emails them, reads the replies, pulls out the prices and lays them side by side. You never write an email.
When a shop offers a time, book it in a tap. It goes on your calendar, you get a reminder the day before, and cancelling sends the shop a note.
The part most people put off: calling four shops to ask what something costs.
Confirm your mileage, pick the work from a list or describe it yourself, and choose how many shops to contact.
KarHub drafts the email with your vehicle details already in it. You read it, edit it, and decide whether it goes.
Prices, line items and available times are pulled out automatically — alongside the shop's actual words, so you can check them.
Shops often ask a question back. Answer it yourself, or have Otto draft a reply after asking you what only you would know.
If you run a repair shop and received a quote request from quotes@mail.karhub.app,
here is exactly what that is.
Someone using KarHub wants a price for work on their own car. We send the request on their behalf and pass your reply straight back to them.
Just hit reply. Your answer goes to the person who asked. There is no portal, no signup, and nothing to install.
We do not charge shops, take a commission, or rank anyone by payment. There is no fee of any kind.
Reply STOP and we will never email that address again for any customer. No reply needed beyond that word.
Questions or a problem with a message you received? Email 1challahadley@gmail.com and a person will read it.
Tracking your car is free, permanently. KarHub Plus covers the features that cost real money to run.

Subscriptions are billed through your Apple Account and renew until cancelled. You can cancel any time in your Apple subscription settings; cancelling stops the next renewal and access continues to the end of the period you have paid for. Full detail in the Terms of Use.
KarHub has no advertising, no analytics SDKs, and no third-party tracking. Your location is used on your device to find nearby shops and is never sent to our servers. Questions you ask Otto — and the vehicle records that give them context — go to Google's Gemini API to be answered; nothing else does. You can delete your account, and everything in it, from inside the app.
