Birdog vs GanttAI

Birdog is construction scheduling and communication software for builders coordinating subcontractors. Its Gantt schedule calculates dependencies, float, and the critical path, with resource planning and schedule templates. Publishing a schedule queues reminders for subcontractor tasks, with follow-ups continuing while work is underway. Subcontractors can reply by text without installing an app or creating a login. Birdog says its AI reads replies in English and Spanish, including questions and reported delays. A delay can prompt a proposed schedule change for contractor approval or rejection; the downstream schedule recalculates after approval. A 6 AM digest summarizes confirmations, active work, schedule changes, and upcoming tasks. Birdog runs on Android, iOS, and the web. The Project license costs $150 a month per project license, with the whole team included at no extra cost. New customers may be offered a 30-day trial for one project; it requires a payment method and renews as a paid monthly subscription unless canceled before the trial ends.

GanttAI is a web tool for specialty contractors and subcontractors who need to locate their work in a general contractor’s construction schedule and understand the effects of revisions. It opens PDF, MPP, XER, XML, and Excel schedules as searchable schedules, identifies activities within a contractor’s scope, and compares revisions across dates, durations, logic, and sequence. Comparisons can be shared through report links that recipients can view without an account. 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 schedule questions in plain English 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. A free trial is available, with one project, two reviews, and one comparison; no card is required. Paid plans start at $250/month for Single, with other plan prices listed separately.
