BPMN diagram generator

Generate BPMN 2.0 Diagrams with AI — in Seconds

Describe any business process in plain language and get a standards-compliant BPMN 2.0 diagram with proper pools, lanes, gateways, and events. Every element is editable; export to SVG, PNG, or JSON when you're done.

What makes a real BPMN diagram

BPMN 2.0 (ISO/IEC 19510) is the international standard for process modeling. It defines precise semantics for each element — circle events, rounded-rectangle tasks, diamond gateways, and rectangular pools divided into lanes. A compliant BPMN diagram can be imported into automation engines like Camunda, jBPM, or Flowable. A generic flowchart cannot.

flow-chart.io generates typed BPMN 2.0 objects, not freeform shapes. The AI applies correct notation automatically: start events are thin circles, exclusive gateways are diamonds with an X, tasks follow verb + noun naming. A built-in audit pass checks compliance before delivery.

  4. Edit and export — click any node to rename or restyle; export as SVG, PNG, or JSON.

Frequently asked questions

Do I need to know BPMN notation to use this?
No. You describe the process in plain language; the AI maps it to correct BPMN 2.0 elements automatically. The audit advisor highlights any compliance issues and explains how to fix them.
Can I edit the generated diagram?
Yes. Every element is a live scene-graph object. Click to rename, drag to reposition, or double-click a connector to add a label. Nothing is a static image.
What export formats are available?
SVG, PNG, and JSON. The JSON export captures the full typed structure so you can reimport the diagram into flow-chart.io later.
How does flow-chart.io differ from a generic AI diagram tool?
Generic tools generate freeform shapes that look like BPMN. flow-chart.io generates typed BPMN 2.0 objects — gateways, events, and tasks with correct notation and an audit pass to verify compliance.
