The ratio of meaningful content words (nouns, verbs, adjectives, adverbs carrying actual meaning) to common filler words (articles, conjunctions, prepositions) is a rough signal of how information-dense a piece of writing is.
This tool filters out a standard list of common English stop words from your text, then calculates what percentage of your total words are these meaningful content words versus common connective filler.
A higher content word ratio often correlates with denser, more information-packed writing, while a lower ratio suggests more conversational or flowing prose — neither is inherently better, but the ratio offers a useful lens for understanding a text's style.

Frequently asked questions
What counts as a 'stop word' in this calculation?
Common English function words like "the," "a," "and," "of," "in," and similar high-frequency connective words that carry grammatical structure but limited standalone meaning.
Is a higher content word ratio always better writing?
Not necessarily — it depends on context and goals; technical or academic writing often has a higher ratio, while natural conversational prose typically has a lower one, and both can be effective for their purpose.
