WHAT IT DOES

Checks zero-width characters, direction controls, soft hyphens, variation selectors, em dashes, and en dashes.

Hidden artifacts are removed and long dashes become standard hyphens. Your wording and safe formatting remain intact.

Analysis happens locally in your browser. There is no server processing or saved text.

UnmarkAI is a text-cleaning utility—not an AI detector or a guarantee of authorship.

* Your pasted text stays in your browser. It is not sent to UnmarkAI, Google Analytics, or a text-processing server.
* Optional analytics: after consent, Google Analytics may receive page views, coarse text-length ranges, and button-click events. It never receives pasted or cleaned text.
* Detection scope: the tool finds selected Unicode controls and long dashes. It cannot detect or remove every watermark, including provider-specific statistical watermarks such as SynthID.
* No authorship verdict: long dashes and hidden characters can occur in human writing and ordinary software. A finding does not prove that text was generated by AI.
* Review before use: normalization can affect legitimate punctuation or language-specific formatting.

By using UnmarkAI, you remain responsible for reviewing the output and following any applicable publication, academic, employment, or platform rules.
