Inspect and change text locally
Try the prepared word changes against Declawd’s public detector, or see exactly which listed Unicode characters your text contains before deciding to remove any. Your text is not sent over the network.
This page does not detect or remove Claude’s watermark.
Anthropic says hidden characters are not its text-mark carrier. Unicode cleaning does not directly target that carrier, and neither it nor rewriting here can certify an Anthropic detector result.
This page tests Declawd’s published watermark and changes only the characters or words you select.
The separate SynthID-Text fixture explains a public token-scoring profile without accepting text.
Do not use these results to judge a person.
The cleaning controls need JavaScript because every inspection and change runs in your browser rather than on a server. With it switched off, the explanations remain available but no text is processed.
Prepared word changes
The marked passage begins at 0.77. Each of the 6 changes below is pinned to a scalar offset in the original passage, which keeps repeated words from being confused with one another. Applied together they move the full-passage score to -0.21, which is below threshold at the 2.30 cut-off.
The source passage already starts below the cut-off. These edits measure a further score reduction, with no threshold crossing.
One green context is worth about 0.12 on this passage. The registered procedure tries up to six changes, choosing the largest available score reduction each time from the reviewed template candidates. It reports the result even if it remains above the cut-off.

Replace words one at a time
Paste text to inspect the counted contexts in Declawd’s public test. Until the text reaches 200 distinct pairs, this mode shows only the count and how many more are needed. It does not show a score, verdict or editing table for shorter text.
Once there is enough text, select a counted green context, enter one replacement word and preview the full-passage result. Nothing changes until you approve that exact word.

Listed Unicode characters
Finding or removing a listed character does not show that AI was involved. Joiners, direction controls, variation selectors and spaces can carry meaning.
This inspector uses a fixed, disjoint registry. It selects nothing by default and performs no Unicode normalisation, homoglyph folding or automatic replacement.
This browser mode removes listed characters only. The public command-line tool also supports exact, user-requested code-point replacements; this page does not replace or normalise spaces.
Language warning: joiners and direction controls can shape Persian, Arabic, Urdu, Hebrew and Indic text, or make it readable, so stripping them can damage that writing. Variation selectors can change how an emoji or ideograph renders.
