FAQ

Questions about pert / gantt templates

What is an activity on node diagram?

An activity on node (AON) diagram is a project management tool that uses nodes to represent activities and arrows to show dependencies, helping you visualize the critical path and task order.

How is an AON diagram different from an AOA diagram?

In AON, activities are on nodes with arrows indicating dependencies. In activity-on-arrow (AOA), activities are on arrows and nodes represent milestones.

Can I calculate the critical path with this tool?

Our online maker allows you to manually define durations and dependencies; for automatic critical path calculations, consider dedicated project management software.

Is this free to use?

Yes, it is free with a free account. No credit card is needed.

What formats can I export?

You can export your AON diagram as an image (PNG), vector (SVG), PDF, or share a live link.
