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

PatentQuill is a software tool for preparing patent-application drawings from the text of a patent specification. It converts written procedures into USPTO-style black-and-white method flowcharts and turns described components and relationships into system block diagrams. Users can inspect diagram boxes and reference numerals, with each box linked to the sentence in the source specification and numerals checked against its description. A separate browser-based checker reviews finished sheets against the formatting requirements of 37 CFR 1.84. The workflow is intended for patent attorneys, patent agents and inventors assembling drawings for USPTO applications. PatentQuill supports diagram preparation and checking; it does not replace professional review or provide legal advice.
