Ask in plain English, get markups on the drawing
Say "count every power outlet" or "measure the wall lengths on level 2" and the assistant places the counts and calibrated measurements directly on the sheet. No tool-by-tool clicking to start.
AI takeoff
AI Construction Takeoff Software
ContractorCounter pairs a browser-based markup workspace with an AI assistant: tell it what to count or measure in plain English and it places the counts, draws the markups, and sets the scale on the real drawing, then you confirm before anything counts.

- AI counts and markups from a chat
- Calibrated measurement + scale detection
- Human review on every result
- Runs in the browser, nothing to install
You stay in control
AI proposes; you decide. Every count and markup lands in the same review workflow you already use (accept, reject, or refine), so the quantities you price from are ones you checked.
From takeoff to a priced quote
Quantities flow into a live bill of quantities and into a takeoff that becomes a quote, so the AI's work connects to the number you actually send.
Common questions
Short answers for contractors
Is the AI takeoff fully automatic?
No, and that is deliberate. ContractorCounter's assistant does the heavy lifting (placing counts, drawing markups, setting the scale) but every result drops into a review step you control. A takeoff you cannot check is a takeoff you cannot trust, so the contractor confirms before quantities are final. US$14/month on the Pro plan.
Which AI model does it use?
It runs on Google's Gemini models, with a Pro tier tuned for reading drawings and a forced higher-accuracy model for scale detection, because a wrong scale would corrupt every measurement downstream.
Is ContractorCounter only for estimating?
ContractorCounter is focused on drawing markup, PDF annotation, calibrated measurement, counts, stamps, comments, and clean exports. Estimating can happen after the markup work is clear.
Does it work in the browser?
Yes: ContractorCounter is fully browser-based, which means it runs on Windows, macOS, and iPad without an installer, a Windows-only desktop dependency, or a virtual-machine workaround for Mac users. Upload PDF or image drawings, calibrate the scale once per sheet, and the full markup, measurement, and counting workflow runs in the tab, at the desk or on site. Because the workspace lives in the browser, the same drawing opens identically on every machine, so the office and the field are always looking at the same markups without anyone syncing files or matching software versions. If your team has been locked out of desktop-first tools on Mac or iPad, this is the structural difference to test first.
