As Diferenças visuais compara e mostra diferenças entre os documentos renderizados (ou exibidos), ao contrário de mostrar o texto (ou marcação) que é usado para formatar esses documentos.
Since 2017, the main approach for visual diffs in MediaWiki is the visual diffs system (pictured) provided by the VisualEditor extension, which compares the HTML of two documents. It provides visual diffs in VisualEditor's editing preview, as well as (still as a beta feature) in MediaWiki's standard diff display.
Previous attempts at visual diffs in MediaWiki include:
- Wiki Edit History Analyzer was another apparently-abandoned attempt at visual diffs; its development was discussed in the 2010 paper "What Did They Do? Deriving High-Level Edit Histories in Wikis".
- IBM's history flow as an alternative concept
- Replay edits tool shows some visual diffs
