What Content Polisher does
Content Polisher scans the text of your posts, pages and public custom post types for small mistakes that are easy to miss: double spaces, spaces before punctuation, missing spaces after punctuation, wrong dashes, empty paragraphs and duplicate line breaks.
Each issue comes with a Before / After preview. Clear-cut mistakes are safe fixes that you can apply one by one or for a whole post at once. Anything that could be intentional is a suggestion and waits for your review. Every change is backed up and can be undone.
Everything runs on your server. The free plugin needs no account and no API key, and it never sends your content to an external service.
