A Ganttastic project plan showing tasks laid out across ten weeks with dependency arrows and a today-marker
The problem

If you plan projects in a spreadsheet, you’re doing it twice.

First when you type the dates. Again when someone asks what moves if a task slips. Ganttastic keeps the structure of a spreadsheet and adds the one thing it can’t do: show you the plan.

A spreadsheet of tasks with Start, Finish, and Dependencies columns
Monday morning. The plan’s in the dates — but you have to imagine it.
The same tasks as a Gantt chart with dependency arrows and a today marker
Friday afternoon. Same data. Drag a task, everything downstream moves.

Paste an Excel plan in and Ganttastic keeps your columns. Keep the spreadsheet if you want — export back anytime.

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.

Try the AI planner

Around 50 AI plans per month on Professional. No usage throttling for normal teams.

Project Planning Simplified.

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.

“We were drowning in spreadsheets and Slack threads. Ganttastic gave us one source of truth for the whole team. Dependencies just work.”

Sarah ChenProduct Lead, SaaS startupLed 5-person cross-functional team.

“Our steering committee wanted a timeline we could actually maintain. This beats redrawing in Excel every Friday. The drag-to-edit is game-changing.”

Marcus JohnsonInfrastructure PM, mid-size firmManaging 40+ concurrent projects.

“Sent stakeholders a read-only link instead of a PDF deck. They could see the actual plan, ask questions, and we didn't need to re-export. Saved hours.”
