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

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. - Easy and intuitive navigation and UI - Quickly switch between building and publishing. - Huge range of customization options for beautiful documents - Share and open anywhere using links or html files - 2D and 3D views - Custom categories and structured properties - Custom connector types with directional arrows, labels, colors, weights - Local MCP connection and BYOK brings the power of AI to creating and understanding your work - Wikilink (Obsidian) and Mermaid compatibility - Insert any files of any type to link them into your project - Folder bridges jump between your spaces - All local. You set the terms. You choose where your data resides - not us. - Built-in help playground, feature suggestions, bug reporting and granular adjustments
