About Sentence Complexity Analyzer
Sentence Complexity Analyzer is used to analyze sentence length and complexity in a text to identify overly long or difficult sentences that reduce readability. It measures average words per sentence, flags sentences exceeding a configurable length threshold, and computes a readability grade level. Aim for an average sentence length of 15-20 words for web content — mix short punchy sentences with longer ones to create natural rhythm. Sentence Complexity Analyzer runs free in your browser at abovetool.com — no signup required.
