GanttTool review
A capable free Gantt editor with AI assistance, exports, and no-account access.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
GanttTool is a web-based Gantt chart maker for planning tasks, dates, dependencies, milestones, project phases, and resource allocations. It suits individuals and teams working on software development, marketing campaigns, event planning, construction projects, and other timeline-based plans. The visual editor is backed by PlantUML, while task completion percentages, custom styling, and cycle detection support detailed schedule editing without requiring an account.
The Free plan costs 0 and includes unlimited projects, no watermarks, and no account required. Its feature set covers visual Gantt editing, task dependencies, milestones, resource allocation tracking, project phases, and completion percentages. Natural-language AI chart editing is a notable addition for users who want to modify a chart through plain-language instructions. Charts can be exported as SVG, PNG, PDF, or PlantUML code, while JSON import and export support project portability. Local browser auto-save provides a way to retain work in the browser, and custom colors, fonts, and styling offer presentation control.
GanttTool is most suitable for free users who need a focused browser tool for building and sharing timeline charts, especially when AI-assisted editing and flexible exports matter. Its scope is narrower for teams that require verified critical-path analysis, baseline tracking, workload management, or integrations with other platforms. Users seeking those capabilities should consider a Gantt product built around deeper project controls or a broader integration ecosystem instead. For straightforward planning with dependencies, milestones, resource allocation, and local saving, GanttTool keeps the entry point simple and avoids account setup.
