Construction Markups, made easy.

ContractorCounter (also written Contractor Counter) is browser-based construction drawing markup software. It gives contractors and reviewers one place to annotate PDFs, calibrate scale, measure accurately, place stamps, track counts, and export clean marked-up drawings without desktop-only tooling.

Yes. The demo at the top of the homepage is the real workspace running on a sample sheet — mark it up, calibrate it, and measure it without creating an account. When you want your work saved, create an account, choose Pro or Team, and add a card to start a 3-day free trial.

A card is required to start the 3-day free trial on Pro or Team. Stripe shows the first charge date before you confirm, you are not charged during the trial, and you can cancel before it ends. The trial includes uploads, markup, calibrated measurement, counts, clean exports, a trial AI allowance, and the bill of quantities.

Pro is for estimators who live in the drawings, and Team adds per-seat shared workspaces; both subscriptions start with the same card-required 3-day trial. Lifetime is the Pro feature set for a single one-time payment and does not include a trial. You can cancel a subscription or switch plans anytime from Settings.

No installs. ContractorCounter runs entirely in the browser, so your team can open drawings, add markups, and export annotated sheets without heavy desktop software. Because it's browser-based, the same workspace works on iPad, Android tablets, Mac, and Windows — on site or in the office, with no app-store download.

Your drawings are private by default and stored in a secure workspace with encrypted handling. Only people you invite to a shared workspace can see your projects, so office and field teams can review the same sheets together.

Yes. You can calibrate a drawing and then use measurement and count tools directly on the sheet. That makes ContractorCounter useful for preconstruction review, scope checks, field coordination, and markup preparation ahead of estimating.

Ask it in plain English — "count the doors on this sheet" or "measure the kitchen floor area" — and it places real markups, counts, and measurements on the drawing. Everything it places is a normal markup you can check, edit, or delete, so you stay the judge of the numbers. The assistant is included in Pro and above.

The platform is built around practical construction markup tools — text, callouts, arrows, highlights, clouds, stamps, counts, and calibrated measurements — to make plan review faster, clearer, and easier to share. It supports common construction drawing formats including PDF plus standard images such as PNG and JPG, covering most plan sets shared by architects, consultants, and clients.
