Windows-only desktop
No native Mac client.
On-Screen Takeoff installs per Windows PC. Mac-based estimators end up on virtual machines, remote desktops, or a shared Windows box — all slower than the work.
On-Screen Takeoff Mac alternative
An On-Screen Takeoff alternative that runs on your Mac
On-Screen Takeoff is a Windows desktop application. If your estimating team works on Macs — or splits time between the office, the job site, and home — a per-PC install is a hard wall. Boon runs in the cloud: upload a plan set from any browser, and the AI does the takeoff, reads the specs with the drawings, and returns a bid-ready package in Slack.
Why Mac teams switch from On-Screen Takeoff
On-Screen Takeoff is capable desktop software with a long track record. The friction is the platform: Windows-only, licensed per seat, and quantities still have to travel to a separate estimating package before a bid comes together.
Per-seat licensing
Every estimator is another seat.
Desktop licensing ties cost to headcount. Boon runs in the cloud, so the whole team works from the same plan set without another install.
The handoff
Takeoff is only half the job.
Quantities out of On-Screen Takeoff still need bid assembly elsewhere. Boon reads drawings and specs together and returns the bid-ready package, not a quantity file.
What Boon does differently
Boon is an AI estimator, not a measuring tool. You upload the plan set; the system does the takeoff across trades, cross-checks the specs against the drawings, and flags mismatches before they turn into change orders.
AI takeoff
The measuring is done for you.
Boon's Construction Vision Model reads every sheet and returns quantities across trades — published per-trade F1 scores included, so you can check the accuracy claim yourself.
Specs + drawings together
One read, not two.
Spec requirements are checked against what is actually drawn, and conflicts surface in the package instead of in the field.
Slack-native delivery
The package comes to you.
Results land in your Slack channel as a bid-ready package. No software to install, no file to import, works the same on a MacBook as on a site PC.
See Boon on your own plans
Book a 20-minute call, or skip the call entirely: email a plan set to plans@getboon.ai and the bid-ready package comes back to you.
