How Does the Unique Word Finder Work?

  • Step 1: Normalization. The tool converts your text to lowercase to avoid duplicate words due to capitalization ("The" = "the").
  • Step 2: Punctuation Removal. All standard punctuation (commas, periods, etc.) is stripped. Words like can't become cant, unless they’re contractions.
  • Step 3: Splitting. Text is split on spaces and hyphens. Contractions (don't, it's) are counted as single words. Hyphenated words (well-being) count as one word unless used with spaces.
  • Step 4: Counting. Each unique word is stored once, and its frequency is counted for easy analysis. Numbers and symbols are included as words.
Special cases: Words with apostrophes (O'Reilly, can't) are treated as single words. Hyphenated words are preserved if they appear as one word. Words with numbers (e.g., "4th", "2025") are included. Emojis and non-English text are skipped.

Frequently Asked Questions

Unique words are counted after converting all text to lowercase and removing standard punctuation. Contractions (like don't) are treated as a single word. Hyphenated words (like state-of-the-art) are counted as one if written together, or as separate if spaced. Numbers and symbols are included as unique terms. Words are split on spaces and hyphens but not on apostrophes, so "it's" and "its" are counted separately.
