## The answer, as recorded

Asked on 2026-09-21 through Claude (Anthropic) with web search (model claude-opus-5).

> There's no single winner - the right pick splits mainly by what you bid (residential vs. commercial vs. heavy civil) and whether your bottleneck is measuring quantities or pricing them. Here's who I'd actually name, in order:
> 
> **1. STACK** - My default recommendation for most commercial and mid-market GCs and subs. Cloud-based, fast takeoff that rolls into assembly-based estimates, unlimited users on most plans, and there's a genuinely free tier to test it before committing. Paid plans start around $299/mo. Best combination of capability-per-dollar and low onboarding pain.
> 
> **2. PlanSwift (Trimble)** - The alternative to STACK if you want a desktop tool and hate subscriptions. Roughly $1,595 as a one-time license, which pays for itself fast versus monthly pricing. Takeoff-first workflow: mark up the plans, quantities flow into costed line items. Downside is it's desktop-bound and less collaborative.
> 
> **3. Buildxact** - Best for small-to-mid residential builders and remodelers coming off spreadsheets. Takeoff, estimating, and basic job management in one place. Now ~$199/mo for unlimited users on the Foundation tier, though scheduling got pushed up into the $399/mo Pro tier in mid-20

Answer Watch records what one AI answer engine said on one date, nothing more. Each page names the engine and the model, carries the date the question was asked, and lists the brands that appeared in the answer in the order the engine gave them, with the sources it cited. It is a measurement, not a ranking, not a recommendation and not a claim about the world. Brands that did not appear in an answer are not named on any public page.
