What is Whimsical?

The workspace focused on iterative product development has a playful quality. We assist teams in overcoming product-related challenges more efficiently by offering documentation tools that foster a collective understanding and enhance clarity among team members. This approach not only streamlines the problem-solving process but also encourages collaboration and innovation.

What is Astah Professional?

Astah Professional is a desktop modeling application from Change Vision, Inc. for organizations that design software and systems. It brings UML 2.x, ER diagrams, data flow diagrams, flowcharts, requirement diagrams, CRUD, and mind maps together in one product, which reduces the number of tools a team needs to license and learn. Because Astah stores designs as models rather than drawings, an update made in one place carries through to every related diagram. This keeps design documentation consistent as projects change. Version 12.0, released in July 2026, brings AI into the modeling workflow. AI Chat Copilot and AI-assisted code reverse engineering run on your organization's own API key for OpenAI, Azure OpenAI, Claude, or Gemini, or for an OpenAI-compatible service, so AI usage stays under the contracts you already manage. Local MCP server integration lets AI agents connect to your Astah models. Licenses are available monthly, annually, or as a perpetual license, starting at $11.99 per month. Astah Professional runs on Windows, macOS, and Linux without a separate Java installation, and a 20-day free trial is available.
