BPMN (Business Process Model and Notation) is an international standard (ISO 19510) for visualising business processes. It uses standardised symbols — events, tasks, gateways, and flows — to represent how a process works. BPMN diagrams are widely used for documentation, process improvement, and as input for workflow automation engines like Camunda and Flowable.

Do I need to know BPMN to use BPMN Studio?

No. You describe the process in plain English and the AI handles the notation. BPMN Studio is designed for people who need BPMN diagrams without wanting to learn a modelling tool.

Can I import generated diagrams into Camunda or other tools?

Yes. Max plan users can export the raw BPMN 2.0 XML file, which is directly importable into Camunda Modeler, Flowable, Activiti, and any other BPMN 2.0 compatible tool.

How accurate is the AI-generated BPMN?

BPMN Studio uses a structured conversation to gather process details before generating, and the generation prompt includes explicit BPMN validity rules. The output is valid BPMN 2.0 XML in the vast majority of cases. Complex processes with many exception paths may benefit from one or two refinement rounds.

What AI model does BPMN Studio use?

Free users get GPT-4o mini for both conversation and generation. Pro and Max subscribers get GPT-4o for diagram generation, which produces more accurate and complete diagrams for complex processes.

Process descriptions and diagrams are stored in a Supabase PostgreSQL database with Row-Level Security — each user can only access their own data. The server uses OpenAI's API; conversations are not used to train OpenAI models under the API usage policy.
