Frequently Asked Questions
How is readability analysis different from grammar checking?
Grammar checking catches errors (incorrect usage, spelling mistakes). Readability analysis measures how easy the text is to understand — sentence length, vocabulary complexity, and structure — regardless of grammatical correctness.
What Flesch-Kincaid grade level should business content target?
Business communications: Grade 7–9. Marketing copy: Grade 6–8. Legal documents (required to simplify): Grade 8–10. Academic papers: Grade 12+. The lower the grade level, the more accessible the content is.
What makes a sentence too complex?
Overly long sentences (over 25 words), multiple subordinate clauses, Latinate vocabulary (over 3 syllables), passive voice, and dense noun stacks all contribute to complexity. The analyzer highlights each issue type separately.
How do I reduce the Gunning Fog Index of my writing?
The Gunning Fog Index measures the percentage of "complex words" (3+ syllables). Reduce it by: using shorter word alternatives (use, not utilize; help, not facilitate; show, not demonstrate), breaking long sentences in two, and favoring active voice.
Does the readability analyzer work for non-English text?
The readability formulas were developed for English and work best with English text. Results for other languages may not be accurate — each language has its own readability characteristics and dedicated formulas.
