Estimate English reading ease and grade level from word, sentence, and syllable counts. Compare drafts as one part of an editing review.
How to use
Paste English prose and read the Flesch reading ease and Flesch Kincaid estimates. Compare similar passages rather than judging a single score alone.
Example
Split a long sentence into two, then compare the estimate. Check that the revision still explains the original idea accurately.
FAQ
Does a higher score mean better writing?
No. Syllables are estimated, and formulas do not measure accuracy or usefulness. This implementation supports English text only.

A practical task
Compare passages with similar purpose and audience. A technical definition and a friendly invitation naturally use different vocabulary. Use the estimate to locate long sentences, then revise only when the new wording keeps the necessary precision.
Another useful question
Can I improve a score by deleting specialist terms?
That can remove meaning instead of improving the explanation. Define a needed term clearly and judge the whole passage, not just its syllable count.
Details for interpreting the result
| Detail | Explanation |
|---|---|
| Readability formulas | Readability formulas use measurable features such as sentence length and estimated syllables. They do not understand accuracy, organization, relevance, or prior knowledge. A useful technical term can lower a score without making the sentence wrong. |
| Rate based estimates | An estimated duration divides an amount of text by an assumed rate. It does not observe a real reader or speaker. Change the assumption when the audience, technical density, or delivery style changes. |
| Words and tokens | A word count depends on token rules. Punctuation, apostrophes, digits, and languages without spaces create edge cases. Use the receiving editor's definition when a formal limit must match its own counter exactly. |
| Context and audience | The same fact needs different explanation for a specialist and a first time reader. State the audience, purpose, and terms they already know. Relevant context guides wording more effectively than broad requests to make a text impressive. |
| Words and meaning | Sharing words does not prove that two passages make the same claim. Negation, order, context, and different subjects can change meaning while vocabulary stays similar. Read the passages before making an editorial judgment. |
| Paragraphs and lines | A manual line break and a paragraph boundary serve different purposes. Export tools can map them differently. Inspect lists, addresses, and intentional blank lines rather than treating every visible break as interchangeable. |
