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
Tagsight serves as the authoritative repository for engineering data, efficiently processing your entire set of drawings to compile essential elements such as the instrument index, I/O list, equipment list, line list, and valve list necessary for project execution. It can interpret various documents including P&IDs, single-line diagrams, loop diagrams, datasheets, and cable and junction-box schedules, regardless of whether they are scanned sheets or CAD-exported PDFs. Each tag is systematically categorized according to the standards already utilized in the drawings, which may include ISA 5.1, KKS, IEC 81346, NORSOK, DIN 19227, or specific conventions set by the operating house. An engineer meticulously verifies or amends each entry before any data is finalized, ensuring that the register is thoroughly reviewed rather than taken for granted. Tagsight has the capability to export data in multiple formats including Excel, CSV, TIA Portal XML for Siemens S7, Rockwell L5X for Studio 5000, PLCCreator, DEXPI, JSON, and annotated PDF, facilitating smooth data transitions. Additionally, it offers revision comparison features to ensure that change management reviews highlight only the modifications made. A REST API and an MCP server enable seamless integration with the broader toolchain, enhancing workflows and fostering collaboration across teams. This interconnected approach not only streamlines processes but also improves accuracy and efficiency in data management.
