About BPMN Studio
BPMN Studio (bpmnstudio.com) is an AI-powered BPMN 2.0 diagram generator built by Emilis Mikalajūnas as a 2026 university capstone project. It lets anyone describe a business process in plain English and get back a standards-compliant, editable BPMN diagram — no modelling experience required.
Why it exists
Business process modelling has a learning-curve problem. BPMN is a precise, useful standard, but drawing a correct diagram by hand means knowing dozens of symbols and their rules. Meanwhile, most people who need a process diagram — analysts, founders, students, operations staff — already know their process perfectly well in words. BPMN Studio was built to close that gap: let the human supply the domain knowledge in plain language, and let the AI do the mechanical translation into notation.
The research angle
The project set out to test a specific question: can AI meaningfully reduce the effort of business process modelling? The working conclusion is that the mechanical translation from a described process into BPMN notation is a task current models handle well; the judgment that remains genuinely human is deciding which steps matter, where the decisions live, and what the process is for. Those are modelling decisions, not drawing decisions — and the tool is designed to keep the human in charge of them while removing the drawing toil.
This connects the tool to a small but growing body of academic work on LLMs and process models, including research on process-model representations for LLMs and BPMN generation assistants.
Who builds it
BPMN Studio is designed, built and maintained by Emilis Mikalajūnas. It is an independent project, not affiliated with the OMG, Camunda, or the similarly named tools bpmn.studio (ELMA), bpmnstudio.online, or bmate.app. See the disambiguation guide if you arrived here looking for one of those.
The stack
- Frontend: React, Vite, Tailwind CSS, and bpmn-js (the same rendering engine used by Camunda Modeler and bpmn.io).
- Backend: Express on Vercel serverless functions.
- AI: leading large language models for the conversation wizard and diagram generation.
- Data & auth: Supabase (PostgreSQL with Row-Level Security).
- Payments: Stripe.
