About

Keep your favorite diagram views and UML tools at your fingertips to improve efficiency and productivity. Everything is customizable in the UML diagrams you create with UModel – size, position, color, typeface characteristics, and line styles. Use case diagrams are often considered separately from other software architecture diagrams because they capture project requirements and can define the scope of an application under development. It’s not likely any project will use all UML diagram types – software modeling allows flexibility in preferences and styles, and various tasks require different diagram types. Regardless which diagrams you create, UModel provides an unmatched visual interface and convenient features to make UML modeling easy and fun. Each diagram type has its own toolbar, so the screen won’t be crowded with irrelevant icons. You can turn toolbar text labels on or off and you can display or hide any toolbar.

About

Arialine is an AI diagram generator and Mermaid diagram editor built for engineering and product teams working in Slack. Create flowcharts, architecture diagrams, sequence diagrams, UML, ERD, C4, swimlanes and other technical diagrams from plain language, Slack discussions, or Mermaid code.

Arialine includes history, undo, rewind, branching, decision context, PNG/SVG/PDF/.mmd exports, interactive HTML diagrams, Markdown-to-Slack-Canvas rendering, Mermaid 12 + ZenUML support, and an MCP server for Slack AI.
