The problem
Your takeoff shouldn't live in three tools.
Ruler, PDF viewer, spreadsheet — every hand-off between them is a chance for a measurement to drift or a number to be retyped wrong.
Before — the manual way
- Scale rulers and squinting at printed PDFs
- Every quantity retyped into a spreadsheet
- Formula typos that surface after the bid goes out
- No link between the drawing and the estimate
After — one connected canvas
- Measure on a scale-calibrated canvas — lengths, areas, counts
- Walls and columns grouped by thickness and size
- Quantities flow straight into the BOQ
- One pipeline from drawing to exported estimate
How it works
Four steps from drawing to bid.
01
Upload your drawing
PDF, image, DXF, or DWG — DWG files convert automatically in a background job.

Calibrate scale & measure
Set the scale against a known dimension, then measure walls, columns, and areas directly on the canvas.

03
Confirm OCR suggestions
OCR reads text on the drawing and suggests element labels. You stay in control — confirm or dismiss each one.

Suggestions come from drawing text — nothing is applied until you confirm it.

BOQ, estimate, export
Generate a bill of quantities, apply material rates and usage norms, and export the estimate to PDF or Excel.

Material costing
A rate master plus material usage norms turn measured quantities into itemised costs.
BOQ & exports
An editable bill of quantities with manual line items, exported to PDF or Excel for clients.
