Low-risk artifacts are selected in text mode. Characters that can affect emoji, bidirectional text, line wrapping, or complex scripts remain unchanged for review.

Text editing boundary
Preserve wording during cleanup; review rewriting separately
Selective cleanup removes only chosen Unicode types. Rewriting changes visible language and needs editorial review; neither action can prove that Anthropic’s model-level mark is absent.
Substantive paraphrasing may reduce a detectable statistical signal, but it can change meaning and cannot guarantee watermark removal. No model provider is configured in this MVP.
Text cleanup that preserves visible wording
This page is designed for prose, notes, documentation, and publishing copy. The local inspector separates observable Unicode artifacts from visible language, so you can remove selected characters without automatically rewriting the draft.
Why selective cleanup matters for text
Not every invisible character is unwanted. Low-risk formatting fixes are selected in text mode, while direction controls, joiners, variation selectors, and other higher-risk findings remain unchanged for review.
When text rewriting becomes a different task
Anthropic says heavily edited, paraphrased, translated, or mixed text may not retain a detectable mark. A rewrite changes visible language and can introduce meaning, tone, or citation errors. It should therefore be reviewed as an editorial change—not presented as guaranteed watermark removal.
Clear answers, narrow claims
Frequently asked questions
Can I clean Claude text without changing the wording?
Yes, when you use selective character cleanup. The cleaner removes only the exact code point types you choose and does not paraphrase visible words.
Which invisible characters need extra review?
Direction controls, zero-width joiners, variation selectors, and some spaces can affect emoji, multilingual scripts, display order, or wrapping. They are flagged for review rather than silently selected.
Is the pasted text uploaded?
Current Analyze and Clean operations run in the browser. Rewrite is unavailable because no model provider or server endpoint is configured.
Will cleaned text pass an AI detector?
This tool makes no such promise. Unicode cleanup does not remove model-level statistical signals, and general AI detectors are not the same as Anthropic’s forthcoming mark detection mechanism.
