Frequently asked questions
Is my writing stored or uploaded?
No. Text analysis runs locally in your browser. This site does not send the text you enter to a server or save it in browser storage. If you install third-party analytics or tracking later, revisit this privacy statement.
How is reading time calculated?
We divide the detected word count by 225 words per minute for reading, and 130 words per minute for speaking, rounding up to the next second.
How is keyword density calculated?
We count whole-word, case-insensitive occurrences of your target keyword or phrase, multiply by its word count, and divide by the document's total words. This is descriptive, not an SEO ranking prediction.
Does this tool improve my Google rankings?
No tool can promise rankings. These metrics help you edit content, but search performance also depends on relevance, helpfulness, competition, technical SEO, and other factors.
How accurate is the readability score?
It is an estimate based on the Flesch Reading Ease formula and heuristic English syllable counts. It may be less reliable for non-English text, abbreviations, names, and specialist vocabulary.
