Per-seat cost
Desktop licenses add up.
Every estimator who needs access needs a seat. For a two- or three-person estimating team, per-seat desktop pricing is a meaningful line item.
Free On-Screen Takeoff alternative
Try an On-Screen Takeoff alternative on your own plans first
If you are searching for a free alternative to On-Screen Takeoff, the real question is whether the tool earns its cost. Boon makes that easy to answer: email a plan set to plans@getboon.ai and the AI returns a bid-ready package on your actual drawings — so you can judge speed and accuracy before spending anything.
Why estimators look for a free alternative
On-Screen Takeoff is a per-seat Windows desktop license, and the quantities it produces still need a separate estimating step before they become a bid. For a small shop, that is real money tied up before the first estimate ships.
The hidden second tool
Takeoff alone does not bid.
On-Screen Takeoff produces quantities; assembling the bid happens somewhere else. The true cost is the license plus the hours to finish the estimate.
Try before you commit
Proof on your drawings.
Boon's async path runs your real plan set and returns the package — quantities, spec cross-check, flagged mismatches — so the evaluation is on evidence, not a sales deck.
What you get back from Boon
Boon is AI construction estimating software. It reads every sheet and every spec section as one document, does the takeoff automatically, and returns a bid-ready package in Slack.
Automatic takeoff
No manual measuring.
The Construction Vision Model reads the drawings and returns quantities across trades, with published per-trade F1 accuracy scores.
Spec cross-check
Mismatches flagged early.
Conflicts between the specs and the drawings are surfaced in the package, before they become change orders.
No install
Runs in the cloud.
Nothing to install, no seats to manage. Upload from a browser, results arrive in Slack.
