Browser-based drawing takeoff, markup, and bill of quantities for contractors and estimators
ContractorCounter is a browser-based construction takeoff and estimating platform. Users upload drawings (PDF or images), mark them up, measure at a calibrated scale, count quantities, and export a bill of quantities and priced marked-up sets without installing desktop software.
Why This Tool Exists
Solo estimators and small contractor teams need to review drawings, take off quantities, and produce a bill of quantities and marked-up export, but installing and licensing desktop takeoff software is heavy for their scale.
ContractorCounter runs takeoff, markup, calibrated measurement, and bill-of-quantities generation entirely in the browser, with an AI assistant (Google Gemini) that can place counts and measurements from plain-English requests, all remaining editable and traceable.
