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
Diagram AI is an online diagramming tool that utilizes natural language inputs to create customizable diagrams. Users have the ability to generate various types of diagrams including flowcharts, sequence diagrams, cloud architecture maps, class diagrams, and runbooks, while also being able to modify labels, hierarchy, and layout on an interactive canvas or by directing the AI to reorganize drafts. The platform accommodates PDFs, images, and text as contextual references, facilitates automatic layout adjustments, and maintains a version history for easy restoration. Diagrams can be exported in multiple formats such as XML, SVG, or PNG, making them suitable for use in documentation and presentations. The free tier allows one usage per day and does not permit file uploads, while the Pro and Plus subscriptions provide additional monthly credits and the option to upload files, with the Plus plan offering a greater credit limit. This service is particularly designed to assist product, engineering, and operations teams in documenting their workflows, systems, and architectural designs effectively. With its user-friendly interface and intelligent features, Diagram AI enhances collaborative efforts in visualizing complex concepts.
