ORGANIZATION

Maintenance Tracking

Never miss a service interval again

Build a complete service history for every vehicle you own. Log oil changes, brake jobs, tire rotations, or any repair — with date, mileage, cost, and notes. The app tracks upcoming intervals and flags overdue maintenance so nothing slips through the cracks. Manual logging is free forever with unlimited records.

  • Upcoming interval reminders
  • Overdue maintenance alerts
  • Unlimited service records on every plan

AI VISION

Document Scanning

Point, scan, done

Point your camera at any service receipt, repair estimate, or maintenance sticker. AI vision reads it and files the details — shop, date, mileage, work performed, parts, cost — directly into your vehicle’s service history. No manual entry.

  • Service receipts, invoices, and repair estimates
  • Maintenance reminder stickers
  • Dealer inspection reports
  • Warranty and recall documents
  • Uses AI credits (5 per scan) — available on every plan

AI VISION

Photo Analysis

Show the AI. Get an honest assessment.

Sometimes a picture is worth a thousand words. Photograph worn tires, rust, a leaking hose, or brake pad wear — and let AI vision identify the component, assess the severity, and tell you what to do next. No guessing. No jargon.

  • Tire tread and sidewall assessment
  • Rust and corrosion severity
  • Brake pad and rotor inspection
  • Engine bay fluid levels and hose condition
  • Body damage assessment

OPTIONAL HARDWARE

Tune & Flash History

Has this ECU been flashed?

Every tune and dealer reflash leaves a fingerprint in the ECU. Kaiju Mechanic compares that fingerprint against factory baselines and flags when it’s changed — so you can verify "stock" claims, track your own tune history, and catch unauthorized flashes between service visits. Requires an ELM327 OBD-II adapter and a 1996+ vehicle.

  • Verify "completely stock" claims before buying a used car
  • Track your own tune version history across Stage 1, Stage 2, or dealer updates
  • Catch unauthorized flashes between service visits
  • Detect aftermarket tunes, dealer reflashes, and TSB updates

ORGANIZATION

Vehicle Media Library

Your glovebox, digitized and searchable

An organized digital archive for every vehicle. Store photos, scanned documents, modification records, and service receipts in one structured library — and AI categorizes each upload automatically. Browse by category, timeline, or shop, and search to surface any record in seconds. When you sell a car or file a warranty claim, everything is already organized and in one place.

  • Photos, receipts, and scanned documents for every vehicle
  • AI auto-categorizes every upload
  • Browse by Smart, Grid, Timeline, or List view
  • Search and filter to find any record fast
  • Proof of service ready for resale or warranty claims
Premium

GARAGE

Modifications Tracking

Document your build, part by part

Log every modification to your vehicle — intake, exhaust, suspension, ECU tunes, and more — with parts, costs, install dates, and photos. Note the impact on horsepower or fuel economy, and keep a detailed build record that protects warranty, insurance, and resale value.

  • Track parts, costs, and install dates for every mod
  • Document intake, exhaust, suspension, tunes, and more
  • Record performance impact on horsepower and fuel economy
  • Photo documentation for each modification
  • A build record that protects resale and warranty value
