Every vehicle has a story.
We keep the record.
CarTethra is the permanent, verified, AI-powered service history that follows a car from its first oil change to its final sale — built for owners, dealerships, and manufacturers alike.
Issued 2026
One VIN. One passport. A record that never gets lost.
Link a vehicle to its VIN
Every passport is anchored to the vehicle's VIN — not an account, an app, or a single owner — so the record survives every sale and transfer.
Capture service records automatically
Snap a photo of any receipt and CarTethra's AI extracts the service type, date, mileage, and cost — no manual entry required.
Verify through certified shop partners
Records logged by a certified CarTethra partner shop are marked "Verified" — giving buyers and dealers data they can actually trust.
Get predictive maintenance & cost-to-own insight
CarTethra cross-references OEM-recommended schedules with real history to flag upcoming service and compare cost-to-own across vehicles.
Protect the resale value of every car you own.
Your maintenance history is one of the most valuable things you own — and the easiest to lose. Build your passport in minutes and never lose a record again.
- Scan receipts in seconds — AI does the data entry
- Get reminders based on OEM service intervals
- Share verified history instantly at sale time
Appraise with confidence. Sell with proof.
Pull a verified passport at trade-in to spot deferred maintenance before you take on risk, and merchandise inventory with a "Verified History" badge buyers trust. Manufacturers get aggregated, privacy-respecting maintenance trends by make and model.
Partner with CarTethraMaintenance records are scattered — and everyone pays for it.
Service history lives across dealerships, shops, paper receipts, and glove boxes. CarTethra brings it all under one VIN-linked record.
Owners
Lose track of 60–70% of service records over a car's life, and sell well-maintained vehicles for the same price as neglected ones.
Buyers
40M+ used vehicles change hands yearly with no verified maintenance history — only seller claims that can't be checked.
Mechanics
Repeat diagnostics that a documented history would answer instantly, wasting time on every new vehicle that comes through the bay.
Dealers & OEMs
Can't accurately appraise trade-ins or understand fleet health without a trusted, verifiable service record tied to the VIN.
Accident history and maintenance history are different problems.
Carfax tells you what happened to a car. CarTethra tells you how a car has been cared for — and what it needs next.
