VisualDiff is integrated in the history page of every article. Users can compare versions directly in the flow text in addition to the standard comparison view.

Usage / features


There are three diff views:

  • Visual: The differences are shown in the flow text.
  • WikiText: The output is shown in Wikitext in an integrated view.
  • Classic: The output is in WikiCode.

Tabs allow to switch between the three views.
