Software Ideas Modeler is a CASE tool for designing software and processes with diagrams. It supports more than 110 diagram types, including UML, BPMN, SysML, ERD, and flowcharts. A project keeps diagram elements in a connected model, so an element can appear in several diagrams and edits carry across them. The software can generate and parse source code, reverse engineer code into models, and create SQL creation and change scripts from ER diagrams. Editions range from basic diagrams to documentation and diagram generation, project comparison, cooperation tools, and model versioning. Ultimate lists AI support through the OpenAI API; SVN and XMI import and export are also supported. It can work offline except for downloading, obtaining a license key, and internet-dependent features such as AI tools. Setup and portable packages are available for x64, x86, and Arm64. The maker is based in Bratislava, Slovakia, and was founded in 2009. The product has a free plan for non-commercial use and a 30-day trial.
