Check the site's pricing page for current tier limits and rates. ## 關鍵功能與能力 - **Natural language to diagram:** Describe actors, steps and relationships in a sentence and receive a structured, editable diagram instead of drawing boxes by hand. - **Broad diagram coverage:** Supports the notations software teams actually use — UML class and use-case diagrams, sequence diagrams, flowcharts, BPMN process maps, C4 architecture views and mindmaps. - **Text-based diagram source:** Diagrams are stored as readable text notation, which makes them easy to diff, review and keep in version control alongside the code. - **Iterative refinement:** Keep chatting with the assistant to add participants, split flows or restyle the render without starting the diagram over. - **Browser-based workspace:** Runs in the browser on a desktop machine, with a video walkthrough on the site for first-time users. ## 主要使用情境 - **Explain an API flow fast (Software developer):** Describe the request path between services, clients and queues to produce a sequence diagram for a pull request or design doc. - **Sketch C4 architecture views (Solution architect):** Draft context, container and component level diagrams to communicate a target architecture before detailed design begins. - **Map a process in BPMN (Business analyst):** Turn a written process description into a BPMN flow with lanes and gateways that stakeholders can review and correct. - **Build teaching diagrams (Student or teacher):** Generate class, use-case and flowchart examples for coursework, lecture slides or revision notes in seconds. ## 優勢 - Removes the manual shape-dragging step entirely — you type, it draws - Covers the diagram types engineering teams need, including sequence, BPMN and C4 - Text-based source makes diagrams diffable and suitable for version control - Editor loads quickly in a browser with no local installation ## 限制 - Desktop-only by design, so phones and tablets show a redirect notice - Generated diagrams often need a round or two of prompting before they match the exact convention you want - Complex enterprise-scale models may eventually need a dedicated modelling tool ## 常見問題 ### Do I need to know UML syntax? No. You describe the system or process in ordinary language and the assistant generates the diagram code for you, though you can still edit that code directly if you prefer. ### Why does the site say desktop only? The editor is designed for a larger screen and a physical keyboard, so visiting from a phone shows a notice directing you to a desktop device and to the informational site instead. ### Does it work offline? ChatUML describes itself as a lightweight web app rather than a local installation, so diagram generation depends on the service being reachable. ### Can I use the diagram code elsewhere? Yes. Generated diagrams are expressed in text-based diagram notation, so the source can be copied, version-controlled and rendered by compatible tools. ### ChatUML 的每月流量與成長趨勢為何？ ChatUML 目前每月有 1.48萬次造訪，月流量變化為 +991（成長率 +7.2%）。其主要來源市場為美國（佔比 18.3%），其中包含每月 5930 次直接造訪與每月 — 次自然搜尋造訪。 ### ChatUML 是免費的嗎？其定價模式為何？ ChatUML 採用免費增值定價模式。Freemium: a free tier provides basic use of the AI diagram generator, with paid options available for heavier usage.
