How the workflows compare
ScopeSift drafts siding polygons, duct paths and electrical counts/routes for one chosen trade. STACK creates editable floor-plan areas, wall segments and door/window counts, alongside manual trade tools and Pro estimating. Floor Plan AI runs one sheet at a time; separate STACK IQ workflows have different capabilities.
Detailed workflow comparison
- Area geometry
- ScopeSift: AI draws editable siding-surface and opening polygons on source PDF sheets.
- STACK: Floor Plan AI creates room/gross areas and shows room boundaries on the drawing; measurements use standard editable takeoff objects.
- Line geometry
- ScopeSift: AI traces duct paths and siding trim. Electrical lengths use explicitly drawn routes, not inferred installed wiring.
- STACK: Floor Plan AI generates linear measurements for interior/exterior wall segments. This documented scope does not establish duct-network tracing.
- Siding elevation workflow
- ScopeSift: AI reads elevation material labels and produces siding areas, opening deductions and trim drafts.
- STACK: STACK's siding workflow uses area and surface measurements on plans. Floor Plan AI detects room boundaries and wall segments on floor plans.
- HVAC duct workflow
- ScopeSift: AI produces editable duct paths and lengths, with quantities grouped by recorded size and system.
- STACK: STACK's ductwork workflow measures lengths and assigns items or assemblies for estimating. Floor Plan AI's automatic line objects are interior and exterior wall segments.
- Edit results on the drawing
- ScopeSift: Edit vertices, redraw runs, adjust count markers or remove shapes; saved quantities update with the geometry.
- STACK: AI measurements can be refined with normal tools: drag/add/remove anchors, merge/split shapes and subtract cutouts.
- Object counting
- ScopeSift: AI counts HVAC equipment and air devices, electrical devices and other objects in the selected trade scope.
- STACK: Floor Plan AI counts doors/windows. Separate preset electrical Symbol Counting AI is experimental; sample-based Autocount finds reviewed matches.
- Where you work
- ScopeSift: In your browser. No desktop installation.
- STACK: Cloud-based takeoff and estimating.
- From quantities to estimate
- ScopeSift: Edit the drawing, add your prices, and export CSV, Excel or an estimate PDF.
- STACK: Editable takeoffs, items and assemblies, cost estimates and reports.
- Paid options
- ScopeSift: Buy a single takeoff or choose a monthly subscription.
- STACK: Pro is $349/user/month billed annually ($4,188/year) or $399/user/month paid monthly ($4,788/year). Both require a twelve-month commitment; totals are rate × 12 before taxes and add-ons.
STACK’s pricing and AI product pages list AI Takeoff in Premium and Pro. Its licensing help still describes Floor Plan AI as a separately assigned add-on. The matrix identifies the documented tool; these sources do not establish one consistent inclusion rule for every account.
ScopeSift full-PDF runs are subject to file, page and processing limits.
