Readability Checker
Estimate reading ease, grade level and sentence complexity without uploading your draft.
Check readability without chasing a perfect score
Readability formulas estimate linguistic complexity from sentence length and syllables. They are useful for comparing drafts, but subject matter, audience knowledge and layout also affect comprehension.
Use the result to identify dense passages, then edit for meaning and accuracy rather than mechanically shortening every sentence.
How to use the Readability Checker
- Provide the complete value or source material you want to inspect.
- Run the check and review each result or warning.
- Correct the original source and repeat the check before using it.
Practical example
Keep a copy of the original text when performing cleanup or bulk transformations.
What this tool cannot guarantee
Automated text processing cannot determine every editorial intention, so review transformed content before publishing.
