Extension:Acrolinx

The Acrolinx MediaWiki extension provides integration with Acrolinx, a (paid, proprietary) service that provides spell- and grammar-checking for text. This extension supplies a side window - which can be minimized - in edit pages, which in turn calls Acrolinx to check the text currently being edited.

The Acrolinx extension can be used when a page is being edited with VisualEditor - though, to have it actually make the changes that it suggests, you will need to apply a small patch to the VisualEditor code; this patch is included in the Acrolinx extension code. This extension can also be used for text and textarea inputs in forms defined by the Page Forms extension. It can also work on VisualEditor-based textareas within such forms (which additionally require the VEForAll extension).
