What it does

Engineering, not just drawing

neuralcanvas isn't a generic CAD tool — it understands ductwork. It sizes, routes and checks compliance as you go, so the design that leaves your screen is one you can actually install and price.

AI room detection

Drop in a floor-plan image and it finds the rooms and walls automatically — or draw them yourself.

Auto-routed ductwork

Supply and return trunks, branches, diffusers and grilles — routed and drawn for you in seconds.

Live compliance

Region-aware duct sizing and code checks run as you design, flagging issues before you commit.

Multi-zone systems

Zone dampers, per-zone loads and balanced airflow across a whole building, not just one room.

PDF & bill of materials

Export a client-ready PDF report and a priced bill of materials straight from the design.

Turn a design into a quote

One click sends the takeoff to a priced quote — the start of winning the job, not the finish line.

How it works

A design in three steps

1

Upload a floor plan

Drop in a plan image or PDF, or sketch the rooms directly on the canvas. Set your scale and go.

2

Let it design the ductwork

neuralcanvas detects the rooms, sizes the loads, and draws a routed, code-checked duct system — supply, return and diffusers.

3

Export or quote it

Download a PDF and bill of materials, or turn the design into a priced quote and schedule the install.

neuralcanvas is the design layer of neuralduct — one login that also runs scheduling, invoicing and a branded customer portal. When a design becomes a quote, it becomes a scheduled install, an invoice, and a report your customer can see — no re-keying between tools.
