Ganttastic

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.

Generate a plan from your briefSee an example plan

From Brief to Baseline in minutes.

A Ganttastic project plan with progress bars, dependency arrows, a milestone, and a today marker

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.

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.

1 AI plan/month on Free. Generate on demand from Project Manager.

Easy to use. Hard to outgrow.

Everything you need to plan, track, and share work. Nothing you’d need to train a team to use.

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.

Critical path & baselines.

See what actually moves the deadline and what’s slack. Snapshot the plan to track drift.

Share the plan, not a PDF.

Invite stakeholders as viewers. They see the live plan, and viewers never cost a paid seat.

Every project on one timeline when leadership asks what the team is actually doing this quarter.
