What GanttTool is
GanttTool is a free web app for planning and tracking project tasks, milestones, and dependencies on a Gantt chart timeline. Its AI assistant can create or edit tasks, dates, dependencies, and milestones from natural-language instructions. Scheduling options include dates, offsets, non-working weekends and holidays, and resource allocation tracking; dependencies include validation and automatic cycle detection. Users can reorder tasks with drag and drop, customize chart colors, fonts, and styling, and export charts as SVG, PNG, or PDF. Projects can be saved or loaded as JSON. The site lists software development, marketing campaigns, event planning, and construction as use cases. Its Free plan costs nothing and includes unlimited charts and projects, no account requirement, and no watermarks. The privacy policy says chart data is processed locally in the browser and is not stored on the maker’s servers. The terms allow personal and commercial use under a free license, while stating the service is provided as-is without a guarantee of secure or uninterrupted access.
