Source-aware schedule
A supported vehicle starts with documented maintenance semantics instead of a generic reminder list.

Know what your car needs next.
One calm place for confirmed history and an explainable next action.
Start with your vehicle and what you know. VehicleOS keeps service evidence reviewable, applies source-aware rules, and leaves the final decision with you.
Five maintenance decisions, built deeply.

Features
One owner-controlled maintenance loop
A narrow early-access product: evidence, a source-aware recommendation, and your decision.
One next action
Home keeps the most relevant maintenance work visible without pretending notification delivery exists.
Confirmed history
Service evidence stays editable and reviewable. A correction immediately updates the next action.
Five focused policies
Engine oil and filter, cabin filter, brakes, tire rotation, and tire replacement — each with its own evidence boundary.
Correct, then recalculate
The assistant does not silently rewrite your history or maintenance interval.
Capture for review
Photos, PDFs, and notes remain evidence for owner review; they are not automatic maintenance truth.
You decide. Record it, fix the evidence, or act when you are ready.
Get started
Three steps to a clearer next action

History reports are a snapshot. General AI can explain once. Neither preserves your confirmed maintenance evidence and next action together.

Scope
Built deeply, not broadly
Owner appNow · early access
Five-policy delivery
Tire rotation is the implemented reference. The remaining four policies are in progress against the same owner-controlled loop.
- Engine oil and filter
- Cabin filter and brakes
- Tire rotation and replacement
ResearchSeparate, consented study
10-PDF CARFAX evaluation
A small paired evaluation measures document extraction without writing into owner history.
- No product event-store writes
- Owner correction is the label source
- No production claim from ten PDFs
How it works
Evidence first. Decision stays yours.
VehicleOS keeps the evidence, source-aware policy, and owner action separate so every next step is explainable.

Built to explain itself
Event-sourced domain · source-aware policy · owner correction. The public architecture shows one focused decision loop, not an unneeded worker or agent platform.
evidence → event → policy → owner

EvidenceOwner-confirmed service facts and attached review evidence02

PolicySource-aware deterministic assessment for one maintenance item04
OwnerSchedule, complete, correct, or decline; then recalculateEvents preserve evidence. Deterministic policies own due decisions. The owner controls every history change. AI extraction, if ever promoted, is measured separately first.
