What is Vexlio?

Boost your drawing efficiency with cutting-edge auto-snap capabilities and smart tools tailored for maximum productivity. You can effortlessly export your creations in high-quality PDF and SVG formats without incurring any subscription costs or monthly fees. The auto-snap function guarantees that objects align flawlessly, resulting in accurate and professional outcomes, while the incorporation of LaTeX equations directly into your diagrams adds a touch of elegance. With innovative tools at your fingertips, routine tasks are simplified, allowing you to dedicate more time to your creative pursuits. Take advantage of powerful Bezier curves and boolean path operations to easily produce detailed illustrations. Vexlio enables you to export your artwork as high-quality PDF diagrams with remarkable simplicity. Just like SVG files, PDFs retain their clarity and smoothness at any scale, making it easy to incorporate compact diagrams in the margins of a paper or showcase larger designs as the focal point of a poster. Additionally, Vexlio’s flexible export system smartly crops your PDF to match the exact dimensions of your artwork, removing any extra hassle for you. You can also choose to export only specific elements, further streamlining your workflow. With these remarkable features, you can elevate both your productivity and creative possibilities to unprecedented levels while enjoying the process.

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.
