How to improve readability
- Break long sentences into one clear idea at a time.
- Prefer familiar, specific words when they express the same meaning.
- Use headings, lists, and whitespace to make information easier to scan.
- Recheck the score, then read the text aloud instead of optimizing only for a number.
How the scores work
Reading Ease gives higher scores to text with shorter sentences and fewer syllables per word. Grade Level expresses similar inputs as an estimated US school grade. Both formulas are useful signals, not judgments of accuracy, tone, or quality, and automated syllable counts are approximate.
