Ganttastic
AI project planning

The AI Gantt chart generator.

Describe your project in plain English and Ganttastic builds a real, editable Gantt chart — tasks, milestones, dependencies, and dates. Not a static image. A plan you can drag, refine, share, and export.

The basics

What is an AI Gantt chart generator?

An AI Gantt chart generator turns a plain-English description of your project into a structured Gantt chart — automatically drafting the tasks, phases, milestones, dependencies, and dates. Instead of starting from a blank chart or a fixed template, you describe what you’re building and the AI creates the plan for you to edit. Ganttastic is an AI Gantt chart generator built for solo PMs and small teams: the output is a real, editable plan you can refine, share with a live link, and export to PDF, Excel, PNG, or CSV.

How it works

Prompt in, plan out.

1

Describe your project

Type or paste a plain-English description — what you're building, roughly how long, and who's on the team. No template or format required.

2

The AI generates the Gantt chart

Ganttastic drafts a structured Gantt chart: tasks and phases, milestones, dependencies, estimated dates, and resource assignments — a working plan, not a blank chart.

3

Edit, share and export

Drag bars, rewire dependencies, rename tasks, assign owners. Then share a live link or export to PDF, Excel, PNG, or CSV.

Generated, not templated

A real plan you can push back on.

Generated, not drawn

The output is a real, editable Gantt — draggable bars, live dependencies, movable milestones — not a flat image or a screenshot you can't change.

Your edits stick

Rename a task, drag a bar, rewire a dependency — the generator won't overwrite your changes. The AI drafts; you stay in control.

Methodology-aware

Ask for PRINCE2, PMBOK, or plain-language structure and the generated plan follows it — a credible first cut, not generic filler.
