Complexity refers to the structural and lexical difficulty of a text (e.g., long sentences, complex words). Readability is the result of that complexity—how easy it is for a person to read and comprehend the text. This tool measures the key factors of complexity to help you improve readability.

 First, analyze your text to get a baseline score. Then, try to shorten long sentences and replace overly complex words with simpler alternatives. Re-run the analysis to see how your scores improve, and aim for a result that fits your target audience.

A lower average syllables per word means you are using more common and widely understood vocabulary. This makes your writing more accessible to a general audience, as they can read and comprehend your content without having to pause and look up words

Yes. Content for children should have a very low complexity score. General audience blogs should be in the medium-low range, while academic journals and legal documents will have a very high complexity score.

While short sentences are good for clarity, a text with only short sentences can sound choppy. A good piece of writing mixes sentence lengths to create a natural rhythm and flow, making the content more engaging.
