Our Vision

We analyze project source code to provide a comprehensive and intuitive view of application components making it easy to learn, support and transfer source code knowledge in your project.


account_tree Visual Representation We present majority of code information as a set of interactive diagrams making it more convenient and effective than conventional methods.

insights Automated Code Analysis We analyze source code to give you a comprehensive view of your current code base. All objects, modules and build scripts will be available in your documents.

view_in_ar Integrated View We present an integrated view of the application components adding source code, HTML, documents and build scripts to the diagram, ensuring a comprehensive picture of your system.

tips_and_updates Always Up To Date Our system collects information directly from code base ensuring that whenever you change your source code or scripts, the changes are automatically reflected in the documents.

draw Capture Knowledge Your Way You can not only view the diagrams but also create new once capturing your knowledge or modeling modification scenarios.

Hey there! I'm an experienced software engineer turned technology director.

Over the years, I've seen my fair share of poorly documented or complex applications that take weeks to learn. And let's be real, the best tool helping you is still a whiteboard and the code editor in your IDE.

But I believe there's a better way. A way where the computer not only helps you explore the application structure, but also assess its complexity and plan changes. I'm on a mission to make this a reality and give developers more time to write code and less time staring at it.

Join me on this journey and make a real difference in your development process.
