Frequently asked questions
Is Great Gantt free?
Yes — the Free plan allows 1 active project with all the essentials: business days, predecessors, subtasks and exports. The Pro plan unlocks unlimited projects and team sharing.
How does AI generation work?
You describe the project in plain text (goal, deliverables, deadlines, team) and AI drafts groups, tasks, efforts and predecessors. The result opens right in the editor for you to refine.
Do I need to install anything?
No. Great Gantt runs in the browser, on desktop and mobile, with automatic cloud saving. Just sign in with your Google account.
How does team sharing work?
You invite people by e-mail with edit or view permission. Everyone sees changes in real time, can comment on tasks with @mentions, and the history records who changed what.
Can I take the schedule to Excel or PDF?
Yes — one-click export to Excel (with chart, notes and holidays), PNG for presentations and PDF, plus an executive status report ready to print.
Does the math consider weekends and holidays?
Yes. Deadlines are computed in business days, and you can add holidays so dates reflect the project's real calendar.
