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

Napkin effortlessly converts your written ideas into visuals, making the process of sharing your thoughts both swift and efficient. Rather than relying on prompts, Napkin operates directly from your text input, generating visuals that are most pertinent to your content. You then have the opportunity to choose the image that best encapsulates your vision. The visuals produced by Napkin are completely customizable, allowing you to modify both the content and style for maximum effectiveness. You can enhance your visuals by adding or substituting icons from a vast collection, ensuring that the aesthetics align with your concept. With dynamic connectors capable of linking various elements, and colors that maintain appeal in both light and dark modes, Napkin's versatility truly stands out. The visuals you create can be applied across various platforms, capturing your audience's attention with auto-generated infographics, diagrams, flowcharts, and more. In essence, Napkin serves as your personal visual consultant, ready to transform your text into engaging visuals like charts, scenes, and images, thus helping you effectively communicate your ideas. This innovative tool not only simplifies the transition from text to visuals but also empowers you to present complex information in a clear and appealing manner.
