- Full traceability linking use cases to requirements, scenarios, and downstream diagrams like activity or sequence.
- Integration into larger UML/SysML projects with version control and team collaboration support.
Imagine starting with a textual description of your system — VP Desktop’s AI generates an initial use case diagram, then you leverage its professional tools to add details, export to code, or generate reports. Unlike basic online sketchers, VP Desktop ensures your diagrams are production-ready, scalable for enterprise teams, and fully traceable — making it ideal for serious architects and developers who need more than one-off generation.
How to Generate a Use Case Diagram with AI in VP Desktop
- From the main menu, select Tools > AI Diagram Generation. This opens the AI Diagram Generation window.
- In the window, choose your desired diagram type from the dropdown list. In this case, Use Case Diagram.
- In the text area, describe your project, problem, system, or scenario.
- Click OK to start the generation.
- The AI will create the diagram automatically.
It appears as a fully editable, native Visual Paradigm diagram (not just an image). You can now:
- Edit elements, relationships, layout, or properties
- Add more details manually
- Export as image (PNG, SVG, etc.), PDF, or use in reports
- Generate code or documentation if applicable
- Edit elements, relationships, layout, or properties
OpenDocs – Embed and Collaborate with Dynamic Use Case Diagrams
OpenDocs redefines knowledge sharing by combining document creation with AI-assisted diagramming. Think of it as a smart wiki or Notion-like platform where use case diagrams become living, editable elements within your content.
Benefits for Use Case Modeling
- Embed AI-generated or custom use case diagrams directly into reports, wikis, or strategy documents.
- Inline refinement keeps diagrams dynamic — update them without switching tools.
- Foster team alignment with interactive content for requirements reviews and stakeholder discussions.
- Support for collaborative knowledge bases where visuals illustrate processes seamlessly.
For teams prioritizing documentation and alignment, OpenDocs eliminates static images. Generate a use case diagram via AI, embed it in a project brief, and let colleagues refine it collaboratively. This platform bridges the gap between modeling and communication, ensuring your visual models remain relevant and accessible.
How to Insert an AI Generated Use Case Diagram into Your OpenDocs Page
- Open or create a page in OpenDocs: Log in to your Visual Paradigm Online workspace, navigate to OpenDocs, and either open an existing page or create a new one (via + New Document Page or similar).
- Insert a diagram: In the page editor, look at the top toolbar (or floating toolbar) and click Insert. From the popup window, select Diagram > Use Case Diagram.
- Start creating the diagram with AI: This opens the diagram editor window. You can build it manually by dragging and dropping elements if you prefer. To use AI instead: Look for Create with AI in the top-right corner of the editor window and click it.
- Describe your use case and generate: In the text input area that appears, type a clear, detailed description of your system or scenario. Click Generate.
- Review, refine, and embed the diagram: The AI generates a professional use case diagram instantly.
Use the intuitive drag-and-drop editor to touch up anything: move elements, adjust labels, add notes, change styles, etc. When you’re happy with it, click Save. Then click Close. The diagram is now embedded directly into your OpenDocs page as a live, editable visual block. You can view it inline without leaving the document.
AI Visual Modeling Chatbot – Conversational Generation and Refinement
The AI Visual Modeling Chatbot turns diagramming into an interactive conversation. Available standalone or integrated with other platforms, it’s perfect for brainstorming, quick prototyping, and iterative design.
How It Transforms Use Case Diagram Creation
- Natural language input: Describe your system (“Create a use case diagram for an online banking app with customer and admin actors”), and get an instant diagram.
- Refinement through dialogue: Ask to “add extend relationships for error handling” or “explain this use case.”
- Export options: Save diagrams, generate reports, or open in VP Desktop for deeper work.
- Ideal for overcoming blank-canvas syndrome in agile teams.
Picture chatting with your AI co-pilot: “Generate a use case diagram for a library management system,” then “Refine it to include optional renewals.” The chatbot handles explanations, iterations, and even analysis — bridging novices to expert-level results fast, without sacrificing quality. This flexibility makes it a game-changer for fast-paced environments.
How to Generate a Use Case Diagram with AI Chatbot
-
Open the AI Chatbot:
- Web access: Go to https://chat.visual-paradigm.com/ (or https://ai-toolbox.visual-paradigm.com/app/chatbot/ as an alternative entry point).
- VP Desktop access: In Visual Paradigm Desktop, select Tools > Chatbot from the main menu. (This opens the same AI assistant integrated within your desktop environment.)
-
Start a new chat session: Click New Chat (on the left sidebar or as a prominent button) to begin a fresh conversation.
-
Describe what you want: In the text input area at the bottom, type a clear description of your project, system, or scenario (e.g. “Generate a UML Use Case Diagram for an online grocery store”). Press Enter (or click the send icon) to submit your message.
-
View and refine the diagram: The AI generates the diagram almost instantly.
This is where the chatbot shines: keep the conversation going! Follow-up examples:
