MarkuClean – Remove AI Artifacts, Unicode & Copy-Paste Characters
MarkuClean automatically cleans WordPress post titles, content, and excerpts by removing AI-generated artifacts, broken Unicode characters, invisible characters, copy-and-paste leftovers, and malformed markup before they are saved.
It detects and removes common issues introduced by AI writing tools, office documents, web pages, PDFs, and other external sources. This includes smart quotes, em dashes, ellipses, zero-width characters, non-breaking spaces, broken encoding sequences, and unwanted editor metadata.
The plugin helps keep content consistent and clean where cleanup is supported. It works with standard WordPress content edited in Gutenberg and TinyMCE-based workflows.
For safety, builder-managed content is skipped. Elementor, WPBakery / Visual Composer, Beaver Builder, Divi Builder, Oxygen, Bricks, SiteOrigin, and similar editors often store structured markup, shortcode trees, JSON-like payloads, or hidden metadata. The plugin returns that content unchanged.
