AAI Text Watermark Checker
Free AI text watermark checker : scan and strip hidden Unicode in the browser
About this tool
The AI Text Watermark Checker is a free web-based tool designed to help you identify and remove invisible characters from your text. Many AI writing tools or text exports can inadvertently insert hidden Unicode characters, such as zero-width spaces or byte-order marks, which can cause formatting issues, break code, or fail validation checks in various platforms. This tool scans your pasted text directly in your browser to reveal these characters.
It solves the problem of unexpected text behavior caused by these hidden elements. Instead of guessing why your text isn't working correctly, you can use this checker to pinpoint and then remove the problematic invisible characters. It's important to note that this tool focuses on visible Unicode characters and does not detect statistical watermarks like those from TextGrain or SynthID, which rely on word choice patterns.
Best for: Users who encounter formatting errors or validation failures when pasting text from AI writers or other sources into different applications.
