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

Filamental allows you to place your thoughts, connect them and present them in a way that is both intuitive and has depth. Limited only by your imagination, add anything, link to anything, share to anyone. Work in 3D or 2D, use physics to keep control, switch between an infinite space and publishing. Add themes, colors, tables, columns, images and backgrounds to enhance your work and make it land. We don't hold your data, IP, documents and personal info hostage. Your data stays on your machine, under your control and you decide where it goes. It is literally impossible for us to gather or see. AI on your terms. Connect your own, we don't force you to use a knock-off we rebranded. It's easy and it's your choice. Free forever and paid options.
