About

Astah Professional is an all-in-one modeling tool for software and system design, developed by Change Vision, Inc. It supports UML 2.x, ER diagrams, data flow diagrams (DFD), flowcharts, requirement diagrams, CRUD, and mind maps in a single tool. Unlike drawing tools, Astah creates models: a change to a model element is reflected in every diagram that uses it, so your diagrams stay consistent. AI features include AI Chat Copilot and AI-assisted code reverse engineering, which use your own API key for OpenAI, Azure OpenAI, Claude, Gemini, or an OpenAI-compatible service. A local MCP server lets external AI agents work with your Astah models. Conventional reverse engineering of Java, C#, and C++ code is also included. Astah Professional is a desktop application for Windows, macOS, and Linux, with a bundled Java runtime, so no separate Java installation is required. A 20-day free trial is available. Latest version: 12.0 (released July 15, 2026).

About

Diagram AI is a browser-based diagramming application that turns natural-language prompts into editable diagrams. Users can create flowcharts, sequence diagrams, cloud architecture maps, class diagrams and runbooks, then revise labels, hierarchy and layout in an interactive canvas or prompt the AI to restructure a draft. The editor accepts PDFs, images and text as context, supports automatic layout adjustments, and keeps version history that can be restored. Diagrams can be exported as XML, SVG or PNG for documentation and presentations. The free plan includes one use per day and excludes file uploads. Pro and Plus plans add monthly credits and contextual file uploads, with higher credit allowances on Plus. The service is intended for product, engineering and operations teams documenting workflows, systems and architecture.
