Where ZapSketch fits
Bluebeam, Drawer AI and Accubid are established tools with far more breadth. ZapSketch starts from the home run: measure it, size it, then price it and hand it off, for a lot less.

|---|---|---|---|---|
| Built for | Measuring and sizing home runs on a plan | Marking up and measuring drawings for any trade | Counting devices and routing branch circuits for bids | Full estimates with labor units and supplier pricing |
| Voltage drop and conductor sizing | Per run, as you draw, with the EGC upsized to match | Not built in. Measure, then calculate elsewhere | Through estimating assemblies | |

Keep it for markup and RFIs. Bring the plan into ZapSketch when you need the wire and conduit for each home run.
Let it count devices. Use ZapSketch to check the long runs it routes before you order the copper.
Size the runs in ZapSketch, then carry the lengths and conductor sizes into your estimate. For smaller jobs, estimate in ZapSketch and export to Excel.
Questions
The marked-up plan exports with a watermark, and the commercial pull and calculation details are redacted. Planning, sizing and checks are not limited.
Yes. Monthly plans stop at the end of the month. Yearly plans run to the end of the year you paid for.
ZapSketch checks your design against NEC 2023 tables and shows the inputs and code section behind every result, so you can stand behind it. Compliance is decided on the job, so follow all applicable codes and regulations.
Yes. Most houses have no plan, so sketch the rooms with typed wall lengths and place the devices. The estimate turns the sketch into a material list, labor and a price, and a customer proposal PDF.
Free during beta. Estimates, the Device Library, the library workbook and proposals are included on the Free plan while they are in beta. They may become a paid feature later, and we'll say so before that changes.
They are starting points. The starter catalog's prices and labor units are placeholders, not market prices or published labor units. Type your own prices and hours, or import a distributor's price file, before an estimate goes to a customer.
Your devices, the parts they install with, and your prices. Edit the built-in devices, make your own with a symbol and a recipe of parts, and every placed copy and estimate follows. Move it all through an Excel workbook, or update prices from a distributor's .xlsx or .csv file.
NEC 2023. The code profile is shown on every project.
No. Import a PDF if you have one, sketch the walls and rooms if you don't, or draw freeform on a blank sheet and type in the run lengths you know.
