Sentence Structure Analyzer
Sentence length, variety, and rhythm suggestions.
Why sentence structure matters
Good writing varies its sentence length. A run of sentences that are all the same length feels monotonous, while mixing short and long sentences creates rhythm that keeps readers engaged.
This tool reports how many sentences you have, their average length, and the range between your longest and shortest sentences. It then flags low variety and suggests adding contrast where helpful.
It is useful for essays, articles, marketing copy, and any writing where flow matters. The tool is free, instant, and your text stays private.
