Our Verdict
Togal.AI and STACK are both cloud takeoff platforms that use AI to cut the time estimators spend measuring drawings, and their entry prices are close: $299 per user per month on Togal's Growth plan (billed yearly) and from $299 per user per month for STACK's Takeoff & Estimate. Where they differ is scope.
Togal.AI is takeoff-first and AI-first. Its AI detects, measures and labels spaces and features on drawings, and the company claims up to 98% detection accuracy and takeoffs about five times faster than manual work. One-click drawing comparison quantifies changes between versions, Togal Chat answers questions about a plan set, image search finds matching symbols across sheets, and sheets are named automatically. It is cloud-only with real-time collaboration and exports to Excel or other estimating tools. Its trades list covers doors and hardware, drywall, electrical, flooring, framing, glazing and painting. The caveats: it does not include an estimating module, there is no free trial or tier, and accuracy claims should be tested on your own drawings.
STACK is a broader preconstruction and field platform. Its takeoff auto-counts symbols, suggests scope and measurements, auto-names pages and flags revisions, and Version Compare overlays drawing versions. Estimating is built in, with items and assemblies, and AI flags risk, gaps and pricing drift. A Build & Operate tier from $49 per user per month covers plan viewing, markup, punch lists and daily reports, and the full platform starts at $348 per user per month. A free version of Takeoff & Estimate is available for new users. The caveats: it has no chat over plans, and its estimating is worksheet-style rather than an enterprise cost database.
Choose Togal.AI if takeoff speed is the bottleneck and you already price work in another estimating tool. Choose STACK if you want takeoff, estimating and jobsite tools from one vendor, or want to start on a free version before paying.
