Drag-and-drop editing.
Move a task, extend a bar, rewire a dependency. The math catches up. No form dialogs in the way, no mode switches to remember. The chart is the editor.
Task shifts two days. Downstream slides with it.
Plan your project in minutes,
not weeks.
Ganttastic turns a messy project brief into an editable Gantt plan, with AI-generated tasks, timelines, dependencies, and resourcing you can share as a stakeholder-ready project plan.
Built by a PM, for PMs.
The problem
Let AI build the plan. You refine it.
Give Ganttastic a messy project brief. It uses the information you provide to draft the tasks, timeline, dependencies, and resourcing, so you can review and refine the plan instead of starting from a blank chart.
AI planning
Describe the project. Get a real plan back.
Tell Ganttastic what you’re building and who’s on the team. It drafts tasks, sets dependencies, and assigns owners — then you edit like any other Gantt. Not a blank canvas. Not a 40-row template. A draft you can push back on.

Re-plan when things slip
Ask it to shift the deadline or swap an owner. Downstream tasks move with the change.
Methodology-aware
PRINCE2, PMBOK, or plain-language — the draft follows the structure you ask for.
Your edits stick
Rename a task, drag a bar, rewire a dependency — Ganttastic won't overwrite it.
