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.
What flow-chart.io generates for BPMN
- Pools and named swimlanes — one pool per participant, lanes per role or department
- All gateway types — exclusive (XOR), parallel (+), and inclusive (O) with labeled exit paths
- Start, intermediate, and end events — plain, message, timer, and error variants
- Task types — user, service, script, send, and receive tasks with correct icons
- Sequence flows within pools and message flows between pools
- Sub-process boundaries and exception paths routed downward from the happy path
How to generate a BPMN diagram
- Sign up free — 5 diagrams, no credit card required.
- Select the BPMN 2.0 domain in the diagram type picker.
- Describe your process — e.g. "Invoice approval: finance receives, manager approves or escalates, accounting pays and archives."
- 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.
