How to Use the Readability Checker
Paste or type text into the checker, and it calculates readability scores (typically Flesch Reading Ease and an estimated grade level) based on sentence and word length — use the result as one useful signal about structural complexity, alongside genuine human review for clarity, accuracy, and overall writing quality.
The Readability Checker calculates standard readability scores instantly — here's how to use the result well.
Entering text and reading the scores
Paste or type the text to check — the tool calculates and displays readability scores based on the text's sentence and word structure, updating as the text changes.
Using the score as one signal, not the final word
As covered in the what-it-measures guide, treating the score as a useful structural signal — flagging genuinely long, complex sentences or difficult vocabulary — rather than the sole measure of writing quality, avoids over-optimizing for the score at the expense of genuine clarity, as covered in the simplification-paradox guide.
