Maintenance Tracking

Never miss a service interval again

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

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.

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 Bluetooth 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
