GanttTool is a free Gantt chart maker that runs entirely in your browser. Build tasks, phases, milestones and dependencies visually, then generate the chart in one click. The AI assistant edits your plan in plain language: "add a 'Beta release' milestone 2 days after testing". Use it and your plan goes to the model, like any AI chat — skip it and nothing leaves your browser. No account, no database, no limits. Save projects as JSON to reopen or share, and export to PNG, SVG or PlantUML.
