ContractorCounter
ContractorCounter is browser-based construction takeoff and PDF markup software with an AI assistant that runs takeoffs as visible, checkable markups. Calibrate scale once, then measure lengths, areas, and volumes, count fixtures symbol by symbol, and mark up sheets with clouds, callouts, and text. Measurements flow into a live bill of quantities you can price and export. Runs on Mac, Windows, and iPad with nothing to install. Includes a genuinely free, no-signup PDF markup tool.
FenceTracer
Fence estimating, takeoff, quoting, and crew scheduling software. Draw the fence, get materials takeoff, send branded quotes. Next Aura Labs Inc.
Quotr.ai
Quotr.ai is an AI-powered construction technology platform designed to modernize the pre-construction workflow for subcontractors, general contractors, and developers. It serves as an all-in-one workspace that replaces manual spreadsheets and fragmented documents with a streamlined, automated system, transforming static construction drawings into actionable data so firms can move from uncertainty to execution in minutes.
ReadMyBlueprint
ReadMyBlueprint is AI takeoff software for drywall, framing, metal stud, insulation and CMU contractors. Upload a PDF plan set and it reads the wall legend and floor plans, then returns linear feet per wall type plus studs, track, drywall sheets, insulation and block counts. Every number is traced to the sheet it came from, and anything uncertain is flagged instead of guessed. First plan set is free; no card needed.
Rooftops AI
Rooftops AI is roofing contractor software: instant satellite + 3D roof reports (area, pitch, facets, waste, cost estimate), verified NWS hail/storm history, Shingle ID from a photo, Roofy AI assistant, and one-click proposals. Free: 3 full reports, no card. Pro $48/mo.
Size The Job
SizeTheJob builds fast, accurate construction-materials calculators that answer one question before you spend money: how much do I need? Free, no sign-up, and every page shows the math. Every calculator runs on one shared, unit-tested math engine. For bulk materials it computes the volume of your area (length × width × depth, with shape options for circles, triangles, and L-shapes), converts to cubic yards (1 yd³ = 27 ft³), and applies the material’s density to estimate tons and bags.
SlabCalc
Free browser concrete calculator: volume, bag counts (40/50/60/80 lb), weight and installed cost for slabs, cylinders, curbs and stairs, imperial or metric, with an adjustable waste factor. No account. Caveat you should weigh before listing it: the calculator itself is deterministic, not AI - only our companion crack analyzer at /analyze is. And our cost figures come from state DOT bid records reprojected onto residential jobs, not contractor quotes, so the ranges are wide.
