Readability scores estimate how hard text is to read, using sentence length and word length. The Flesch reading ease score runs from about 0 to 100, and higher is easier. Around 60 to 70 is plain English. This also gives a school grade, and lists long sentences to shorten. It doesn’t detect AI writing.

## How it works

ease = 206.835 − 1.015 × words per sentence − 84.6 × syllables per word

Short sentences and short words score better. We estimate syllables with spelling rules, so scores are close, not exact.

A score can’t tell you if text is clear or true, so read it too.

Worked example: “The cat sat on the mat.” has 6 words and 6 syllables: 206.835 − 6.09 − 84.6 = 116.1.

## Examples

| Text | Ease | Level |
| --- | --- | --- |
| The cat sat on the mat. | 116.1 | Very easy |
| We test each tool against outside sources. | 91 | Very easy |
| Comprehensive evaluation necessitates interdisciplinary collaboration. | -204.3 | Very hard |

## What this tool doesn't cover

- These formulas were built for English.
- Syllable counts are estimates.
- This can’t tell who or what wrote a text.

## Questions

### What is a good score?

For the general public, aim for 60 or higher.

### Can this detect AI writing?

No. It only measures how readable text is. Nothing here can tell who wrote it.

### Is my text uploaded?

No. Everything runs in your browser, and nothing is saved or sent.

### What is a Flesch reading score?

A score from long-used formulas, based on sentence length and syllables. A higher score means text is easier to read.

### How do I make my writing easier to read?

Use shorter sentences, plain words and active verbs. One idea to a sentence is a good start.
