MarkuClean – AI Markup Cleaner

MarkuClean Markup Cleaner cleans and normalizes post content in supported WordPress editing contexts.

It removes unwanted characters, markup artifacts, and copy-and-paste leftovers from post title, content, and excerpt values. This includes known special characters and malformed sequences commonly introduced by AI-generated content and external copy tools, such as mis-encoded quotes, dashes, ellipses, non-breaking spaces, zero-width characters, and numeric data-start/data-end markers.

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.
