Use this text operation when its stated character encoding, token boundaries, normalization, case handling, and output format match the surrounding workflow.

Text

Required string.

The cited overview of Text processing supplies background for the terminology and domain context used by this tool.^[1]

Check whether any whitespace-delimited word appears more than once, ignoring case. Inputs are interpreted exactly in the displayed units and the calculation returns the following fields without presentation rounding.

Has duplicates result

Returned boolean.

• Unicode normalization, locale, grapheme clusters, malformed input, ambiguous syntax, and implementation-specific conventions can change text-processing results.
• Use finite inputs in the displayed units, preserve source measurements and assumptions, and independently verify consequential decisions.

Preserve the original text, test representative non-ASCII and malformed cases, and use a standards-aware parser or serializer when interoperability matters.

• Isogram Checker

  Check whether no letter repeats in text, case-insensitively, ignoring non-letter characters.

• Stopword Counter

  Count whitespace-delimited words that match common English stopwords, ignoring case.

• Anagram Checker

  Check whether two texts are anagrams by comparing sorted character multisets (case, spaces and punctuation ignored).
