Review the structure behind a code change

Overview Diff organizes Git changes around the declarations they touch, rather than leaving you to work through a long sequence of changed lines.

Use the compact tree in the Commit view to inspect affected classes, methods, constructors, and fields. When details matter, open IntelliJ IDEA's familiar side-by-side diff directly from the selected item.

Built for practical Git reviews

• Explore local changes against HEAD in a declaration-level outline.
• Compare a commit with your working tree, or compare two revisions selected in the Git Log.
• Use the standard IntelliJ diff whenever you want to examine the exact code.

The public beta supports Java for daily work and includes experimental Kotlin support. It requires IntelliJ IDEA 2022.3 or newer.
