Frequently Asked Questions

How is the readability score calculated?

We use the standard Flesch-Kincaid formula which looks at the average sentence length and the average number of syllables per word to estimate the required reading grade level.

What are 'Stop Words' in the Keyword Density tool?

Stop words are very common words like 'the', 'and', 'is', and 'at'. We filter these out so you can focus on the actual descriptive keywords that matter for your SEO.

Are my documents secure?

Absolutely. All text processing occurs client-side using JavaScript. Your text never leaves your device.
