Chapter 01 · The Brief

Designing a job meant
four apps and a flashlight.

Landscape-lighting contractors were stitching together three or four separate apps to design a job, render it, and close a homeowner — all while standing in a dark backyard with no signal. CompanyCam for photos, a rendering tool, a BOM spreadsheet, a proposal app. Nothing talked to anything else.

Matt, of XOutdoorLighting in California, wanted one offline-first tool: capture the lighting design in the field, generate a photorealistic night rendering on the spot, and hand the homeowner a professional proposal before leaving the driveway.

Point, speak,
scene logged.

The contractor points their phone and says "Metro on the Oak." Whisper transcribes it, GPT-4o Vision identifies the surface, and the fixture SKU resolves from their personal nickname dictionary — logged hands-free, no typing in a dark backyard.

Daylight photo,
night render.

A daytime job-site photo transforms into a technically accurate night scene — exact fixtures in exact locations, driven by per-fixture metadata. No generic glow filters: the render reflects the real beam spread, colour temp, and placement of every logged fixture.

A Digital Twin
that sells it.

The contractor's avatar narrates a cinematic walkthrough of the rendered property — auto-scripted from the BOM via HeyGen — and it's shareable with the homeowner on the spot, before the contractor leaves the driveway.

I really value the technical depth you've shown so far — the app's structure needs to be ready to export that fixture data as a prompt.

Consolidation
Apps replaced
by one tool.

The CompanyCam workflow, the rendering tools, and BOM management are unified into a single offline-first app — one design surface, one source of truth.

Chapter 05 · Inside the app
