EstimatorAI is cloud-based construction estimating software that analyzes PDF bid packages, including plans, specifications, scopes, and addenda. Estimators, general contractors, subcontractors, and trade contractors can organize documents by project and ask plain-language questions about quantities, materials, assemblies, exclusions, and scope conditions. Uploads can be up to 1 GB. The software produces a first-pass material takeoff and links answers to source documents for review. Users can check and adjust extracted quantities, then export material and quantity information to Excel or PDF for their estimating workflow. Unlimited projects keep bids organized, and persistent project context lets teams revisit bid details and ask follow-up questions without starting over. Trade-specific workflows cover concrete, masonry, metals, wood, plumbing, HVAC, and electrical. EstimatorAI supports document review while construction professionals verify scope, pricing, and final estimates.
