Maintenance truth, without the guesswork
Give every owner a calmer way to stay ahead of vehicle maintenance.
Keep It Correct is building a source-of-truth maintenance platform for modern vehicles, focused on the intervals that matter most for long life: fluids, transmission and driveline service, filters, ignition, brakes, and condition-based maintenance backed by real citations.

Quick entry points
Give users an obvious place to start instead of making them decode the system.
The first experience should feel like a guided lookup, not a research project. These top paths make the site easier to navigate for both casual owners and detail-oriented users.
Daily-driver flow
Find a vehicle, then move straight into the intervals that actually protect it.
The site should feel less like a data dump and more like a guided maintenance map: start with the car, then narrow to fluids, filters, transmission, brakes, and citations.
Trust-first flow
See where the information came from before you decide what to trust.
A user should be able to move from record to evidence to OEM source quickly, especially when they are comparing severe-use service advice or long-life fluid claims.

Trust layer
Keep the source quality visible so people know why the result is worth trusting.
The site should make OEM and government provenance feel tangible. That adds confidence for users and gives us a clearer path when a record still needs QA.
Toyota
Toyota Owner's Manuals and Warranty & Maintenance Guides
Use maintenance guide PDFs and owner manuals as the authoritative maintenance interval source.
Ford
Ford Owner Support and Scheduled Maintenance Guide PDFs
Primary source for normal and special operating schedules; scrape by make, model, and year.
Honda
Honda Owners Manuals and Maintenance Minder references
Use manuals plus Maintenance Minder guidance where schedules are usage-based instead of static mileage tables.
General Motors
GM Owner Center Manuals and Maintenance Schedules
GM manuals and warranty booklets include brand-specific scheduled service requirements.
Nissan
Nissan USA Owner Manuals
Owner manuals and supplemental maintenance guides are the source of inspection and replacement intervals.
Maintenance scope
Focus the experience on the service items that extend vehicle life.
The product gets more useful when it groups work the way owners think about it: fluids, filters, transmission and driveline service, and chassis wear items.
Fluids
Track replacement and inspection intervals for the fluids that directly affect engine, brake, cooling, and drivetrain life.
- Engine oil and filter
- Transmission fluid
- Brake fluid
- Coolant
Filters and ignition
Surface the wearable items that quietly reduce performance and efficiency long before a failure happens.
- Engine air filter
- Cabin air filter
- Fuel filter
- Spark plugs
Drivetrain and transmission
Separate lifetime-marketing language from practical service intervals for transmissions and driveline components.
- Automatic transmission service
- CVT fluid service
- Manual transmission fluid
- Rear differential service
Chassis and wear items
Keep recurring wear items visible so owners can prevent secondary damage and preserve safety.
- Brake pads and rotors
- Tires and alignment
- Serpentine belts
- Wiper blades
API-first foundation
Give other services a simple contract instead of making them scrape all over again.
Keep the public shape readable: a vehicle, a service item, an interval, a condition, and a citation. That makes the UI easier to understand too.
Authoritative source ingestion
Pull interval truth from OEM manuals, warranty booklets, and government APIs before trusting community or dealer content.
VIN-first normalization
Decode VINs to resolve platform, engine, drivetrain, and trim so interval guidance maps to the exact vehicle a user owns.
Interval-first product shape
Center the system on service items, mileage/month thresholds, severe-use conditions, and citations that other tools can reuse.
Human-friendly maintenance UX
Make the system understandable for non-mechanics with simple service intervals, severe-use warnings, and clearly sourced recommendations.

}Build sequence
Make the roadmap feel understandable, not buried.
The experience gets stronger when the work is legible: discover official sources, normalize intervals, QA them, and then publish them through the app and API.
1. Discover
Find OEM manuals, maintenance guides, and gateway-backed source catalogs.
2. Extract
Turn source text into usable interval records with evidence snippets and confidence.
3. Review
Expose QA status, warnings, and source-specific review queues before calling data finished.
4. Publish
Serve the final shape through a browsable explorer and a stable API for future services.
