AI Text Cleaner
Free cleanup of invisible characters and Markdown formatting in text, plus paid Pro Rewrite, watermark removal, and AI Humanizer features.
About AI Text Cleaner
AI Text Cleaner offers two categories of features. The first is a set of free tools, including invisible character cleanup and Markdown stripping. Invisible character cleanup can remove more than 60 non-printing characters, such as zero-width spaces, ZWNJ, and non-breaking spaces, and according to the official website it runs entirely in the browser. The second is the paid Pro Rewrite feature, used for capabilities that require credits, such as text watermark removal and AI Humanizer. The free scan can only list leftover Unicode characters and cannot remove official statistical watermarks; the latter requires the paid Pro Rewrite to reconstruct the relevant wording.
