Relationships, not folders
Directory layout tells you where someone decided to put a file. A graph tells you what that file actually talks to — which is rarely the same thing.
Point Understand at your project, right-click anything, and the diagram draws itself from the parsed model.
Works on code that doesn't compile · No build system required · Windows, macOS and Linux

Directory layout tells you where someone decided to put a file. A graph tells you what that file actually talks to — which is rarely the same thing.
The diagram is generated from the parse, not maintained by a person. Nobody has to remember to update it, so nobody can forget.
Export the picture instead of describing the problem in a meeting. PNG, SVG and JPEG for slides; Visio and Graphviz when it has to be edited afterwards.
Real-world software is rarely simple. Thousands of files, interconnected components, and years of development make it difficult to understand how everything fits together.
Understand turns those relationships into interactive graphs, helping you explore dependencies, identify important components, and uncover structure that would otherwise be buried in the source code.
Cluster by file or architecture, show every path between two functions, or diff against a previous version — all from the same graph.
Node options, depth limits and legends decide how much of the truth you want on screen at once.
JPEG, PNG, SVG or print. Visio (vdx, vsdx) and Graphviz (dot) when the picture needs editing after it leaves.
“What would have previously taken me several days (or weeks) can now be accomplished in a matter of hours… It's the Swiss army knife of static analysis tools.”

“[Understand] is good for discovering the structure of the code dependencies and call-paths… it would have taken me hours to generate the same thing on my own.”

The trial enables every feature. Point it at your own repository and you will have a call graph on screen before the coffee is cold.
