Readability Improver

The Flesch Reading Ease score runs from 0 to 100. A score of 60–70 is plain English, suitable for most audiences. 70–80 is fairly easy. Above 80 is very easy, like a 6th-grade level. Most general-audience content should target 60–75. Academic or legal content typically scores 30–50.

A grammar checker catches errors (misspellings, wrong tenses, punctuation). A readability analyzer tells you whether correct text is actually easy to understand. Both tools complement each other — use the Grammar Fixer first, then the Readability Improver.

Difficult words are words with 3 or more syllables that are not on the Dale-Chall list of ~3,000 familiar English words. This is the same approach used by the Hemingway App. Words like 'communication', 'utilization', or 'consequently' would flag as difficult while 'important' would not.

Sentences with 14–24 words are flagged as 'hard to read'. Sentences with 25+ words are flagged as 'very hard to read'. These are the same thresholds used by the Hemingway App. Breaking one 30-word sentence into two 15-word sentences significantly improves readability.

The Gunning Fog Index measures how many years of formal education someone needs to understand your text on first reading. A score of 8 is ideal for general audiences. Scores above 12 suggest the text is suitable only for educated adults. Most popular publications target a Fog score under 10.
