Word density is calculated by dividing the number of times a word appears by the total number of words in the text, then multiplying by 100 to get a percentage. For example, if "code" appears 10 times in a 500-word text, its density is 2.0%.
Stop words are common English words like "the," "is," "and," "to" that appear frequently but carry little meaning. Excluding them lets you focus on the most meaningful, content-specific words in your text.
Yes. Use the minimum word length filter to exclude words shorter than a given number of characters. For example, setting it to 3 removes all one- and two-letter words from the results.
