What GanttAI is
GanttAI is a web product for specialty contractors and subcontractors who need to find their work in a general contractor’s construction schedule and follow how revisions affect it. It can open PDF, MPP, XER, XML, or Excel schedules as searchable schedules and identify activities within a contractor’s scope. Its revision comparison covers dates, durations, logic, and sequence, and produces a report link recipients can open without an account. The site says Compare is more than 99% accurate across those areas.
For crew planning, users enter hours by scope and person-day. GanttAI estimates staffing for activities and shows crew peaks against available headcount. Its AI Agent answers plain-English questions about schedules and can create look-aheads or summaries as Excel files. The Portfolio plan adds a cross-project view of trade-level manpower by day, week, month, quarter, or year. GanttAI describes exports for Excel, Primavera P6, Microsoft Project, and PDF. Paid plans include onboarding and support; Team and Portfolio include dedicated support with an account lead. A free trial covers one project, two schedule reviews, and one comparison, requires no card, and does not charge automatically when it ends. The company says customer schedules, drawings, and contracts stay in the customer’s workspace and are not used to train another customer’s model.
Who it suits
GanttAI suits specialty contractors and subcontractors working from general contractors’ schedules who need to locate scoped activities, compare schedule revisions, or plan crews. Teams managing several projects may find the Portfolio plan’s cross-project manpower view relevant.
