What GanttTool is
GanttTool is a free web application for creating Gantt charts that plan and track tasks, milestones, and dependencies on a timeline. Its AI assistant can build or edit tasks, dates, dependencies, and milestones from natural-language instructions. Scheduling supports dates, offsets, non-working weekends and holidays, dependency relationships, and resource-allocation tracking. Dependency validation and automatic cycle detection help check task relationships. Users can reorder tasks by drag and drop and customize chart colors, fonts, and styling. Charts export as SVG, PNG, or PDF, while projects can be saved or loaded as JSON. Listed use cases include software development, marketing campaigns, event planning, and construction. The privacy policy says chart data is processed locally in the browser and is not stored on the maker’s servers. The free plan costs nothing and includes unlimited charts and projects, no account requirement, and no watermarks. Terms grant a free license for personal and commercial use, while providing the service as-is without a guarantee of security or uninterrupted access.
