Description

Astah Professional helps software teams design systems visually, before and while they write code. One application covers UML 2.x, entity-relationship diagrams, data flow diagrams, flowcharts, requirement diagrams, CRUD matrices, and mind maps, so architects and developers do not have to switch tools between notations. Diagrams in Astah are views of a shared model. When you rename a class or change a relationship, every diagram that contains it is updated automatically. For AI-assisted work, Astah Professional 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 work with your Astah models. Conventional reverse engineering of Java, C#, and C++ code works without an AI service. The tool runs locally on Windows, macOS, and Linux and ships with its own Java runtime. Developer: Change Vision, Inc. Current version: 12.0 (July 2026). A 20-day free trial is available.

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.
