Description
Astah UML gives software teams and students a focused tool for UML 2.x modeling. Class, use case, sequence, activity, state machine, component, and deployment diagrams are all available, together with mind maps for early brainstorming.
Every diagram is a view of a shared model, so renaming a class or changing a relationship updates it everywhere it appears.
For AI-assisted work, Astah UML offers AI Chat Copilot and AI-assisted code reverse engineering, both of which connect to OpenAI, Azure OpenAI, Claude, Gemini, or any OpenAI-compatible endpoint through your own API key. A local MCP server lets external AI agents read and work with your models, and conventional reverse engineering turns existing Java, C#, and C++ code into diagrams without an AI service.
Astah UML runs locally on Windows, macOS, and Linux.
Developer: Change Vision, Inc.
Current version: 12.0 (July 2026).
Students can use it free of charge, and a 20-day trial is available for everyone else.
Description
Mermaid is an AI-powered diagram creation and collaboration platform developed by the team behind the open-source Mermaid.js diagramming library. The software enables users to generate diagrams from natural language descriptions, uploaded documents, screenshots, meeting transcripts, and code snippets. Its AI assistant interprets user instructions and creates editable visualizations such as flowcharts, sequence diagrams, entity relationship diagrams, timelines, Gantt charts, and organizational charts. Users can refine diagrams through conversational prompts, direct manipulation in the visual editor, or modifications to the underlying Mermaid syntax. The platform provides a synchronized code editor and graphical canvas, allowing users to switch between text-based and visual editing workflows. Real-time collaboration features include shared team workspaces, simultaneous editing, comments, and diagram sharing through accessible links. Mermaid integrates with developer tools and productivity applications such as Visual Studio Code, GitHub Copilot, Confluence, Jira, and Google Docs. Its Model Context Protocol server allows compatible AI assistants, including Claude and Cursor, to generate, validate, and render diagrams within existing development workflows. Enterprise features include single sign-on, access controls, encrypted diagram storage, administrative capabilities, and SOC 2 compliance.
