Inspect anything against its 3D twin — right from your iPad.
CutCheck overlays your CAD or BIM model onto the real object using LiDAR, then lets AI flag every deviation. No tripods, no point clouds, no office round-trip.
// no credit card required

// the problem
Inspections still run on paper drawings, tape measures, and trust.
A QA round takes a day. Mistakes propagate. Disputes happen because everyone reads the documentation differently. The tools that promise to fix it cost the price of a small car and need a specialist to run.
// the solution
CutCheck collapses the cycle into a single iPad pass.
The model snaps onto reality. AI marks deviations. The inspector signs off in minutes, not days. One device. One person. One signed report — auditable, repeatable, defensible.
// see it in action
A real inspection, in 60 seconds.
// core capabilities
Everything an inspector needs, in one device.
LiDAR-precision scanning
Apple's spatial hardware drives millimeter-grade tracking. No markers, no setup, no reflective targets.
Real-time AR overlay
Reference models snap onto the physical world the moment you raise the iPad — and stay locked.
AI deviation detection
Three specialized models compare geometry, surface every discrepancy, and auto-flag the points worth a second look.
CAD calculations
Surface area, volume, and cut length computed directly from STL, OBJ, GLB, PLY, DXF models. Instant material estimates.
Coating calculator
Polymer and galvanic coating: material mass, cost, and coverage for Zn, Ni, Cr, Cu — straight from the 3D model.
LiDAR measurement
Measure flat surface area and part volume directly through the iPad camera with LiDAR. No extra tools.
Apple Pencil markup
Annotate findings directly on the AR scene. Sketch over reality with the same fluency as paper.
Offline-first
Tunnels, basements, factories without WiFi — everything works. Sync the moment you're back online.
Audit-ready AR recordings
Every walkthrough is captured as an AR video. Repeatable, signed, defensible in disputes.
// process
Four steps. Roughly thirty minutes.
Import reference
Drag in a CAD, BIM, GLB, USDZ, FBX, IFC, or STEP file. Open formats only — no vendor lock-in.
Scan the object
Point the iPad. LiDAR + ARKit lock the model onto reality, accurate to the millimeter.
Review AI findings
Deviations are color-coded live. AI auto-flags inspection points. Confirm with Apple Pencil.
Export the report
Signed PDF, XLSX, deviation heatmap, and AR walkthrough video. Sent in one tap.
// who's using it
Built for the people doing the work.
Construction QA
Walk the floor with the BIM in hand. Compare what's built to what was designed — before the next trade closes the wall.
Manufacturing QC
Sweep the part. AI compares geometry to CAD, flags the deviations, signs the batch. Three times the throughput per inspector.
Insurance loss adjustment
Document a damaged property in a single visit. Evidence no one can argue with — measurements, photos, AR video.
Infrastructure maintenance
Run the same pass every month. Get a longitudinal record of how the structure is aging, with zero spreadsheet upkeep.
// how we compare
CutCheck vs. TwynView.
TwynView pioneered AR quality inspection on iPad — we respect the category they built. We're built differently: one iPad app instead of two, LiDAR-first tracking, and AI that surfaces the inspection points without an engineer setting them up.
// comparison based on publicly available product information, 2026
// what's underneath
Built on Apple's spatial stack and a small army of AI models.
Modern web tech where it matters, native code where it counts, and infrastructure that holds up for regulated industries.
ARKit + LiDAR
Native Swift integration with Apple's spatial framework. Depth maps drive millimeter-grade tracking — no markers, no reflective targets.
AI Vision Engine
Three specialized models in concert: deviation detection, inspection-point auto-suggestion, AR-frame analysis. On-device for offline.
Real-time 3D rendering
Three.js with @react-three/fiber renders complex CAD and BIM at 60fps on iPad Pro and Air M-series.
Offline-first storage
Local-first architecture. Inspections write to device, sync to cloud when online. Conflict resolution built in.
Open formats
GLB, USDZ, FBX, IFC, STEP, OBJ in. PDF, signed XLSX, and audit-grade AR video out. No vendor lock-in.
Enterprise-grade infra
AES-256 at rest, TLS 1.3 in transit. RBAC. Configurable EU / regional data residency. GDPR-aligned. SOC2 in progress.
// from the field
What inspectors are saying.
We cut our QA cycle on a 20-floor build from a week to two days. The dispute log went from twelve items to two.
The auto-flagged inspection points are uncanny — our quality engineers stopped briefing them after the first month.
AR video is the killer feature. Insurers stopped pushing back on our findings the moment we attached the walkthrough.
