About this keyword
Inspect AI paste artifacts with complete transparency
When text is generated by LLMs or copied across modern web interfaces, it frequently carries invisible Unicode markers and distinctive Markdown formatting. Our AI Text Watermark Detector provides an instant inspection view to highlight these artifacts.
This tool checks against a curated catalog of 60 code points, flagging non-breaking spaces, zero-width joiners, and unexpected whitespace anomalies. It lists exact findings so you can verify text hygiene before publishing.
Please note: this is a structural and character-level inspection tool. It is NOT a plagiarism detector, does NOT calculate an "AI probability score" like GPTZero, and does not claim inside knowledge of proprietary model watermarking algorithms.
FAQ
FAQ
How does the AI Text Watermark Detector work?+
It analyzes your text locally against a database of 60 known invisible Unicode characters, control codes, and formatting artifacts, providing a breakdown of every hidden marker discovered.
Does this tool calculate an AI detection score or percentage?+
No. This tool detects inspectable Unicode characters and formatting residue. It is not an AI classifier, does not assign probability percentages, and is not a replacement for statistical detectors.
Is my inspected text kept private?+
Yes. All detection logic executes locally within your browser. Your draft is neither uploaded nor logged on our servers.
What should I do if the detector finds hidden characters?+
You can strip them immediately with our free one-click cleaner. If you also need to address repetitive phrasing or structural AI patterns, you can switch to Pro rewrite to regenerate the wording.
