GanttAI
Toronto, Canada
What it is
GanttAI is a web service for specialty contractors reviewing construction schedules and planning crews. It opens PDF, MPP, XER, XML and Excel files as searchable schedules, then identifies activities within a subcontractor’s scope. Revision comparison covers dates, durations, logic and sequence, with a shareable report link that recipients can open without an account. Users enter hours by scope and person-day so GanttAI can estimate staffing and show crew peaks against available headcount. Its AI Agent answers plain-English schedule questions and can create look-aheads or summaries as Excel files. The Portfolio plan adds cross-project trade manpower views by day, week, month, quarter or year. Listed formats and exports include Microsoft Project, Primavera P6, Excel and PDF. GanttAI says schedules, drawings and contracts remain in the customer workspace and are not used to train another customer’s model. A free trial includes one project, two reviews and one comparison, requires no card, and does not charge automatically. Plans begin at $250 a month.
