Reading Time & Keyword Density Checker
Free reading time and keyword density checker for articles, essays, and web copy. Analyze words, characters, sentences, and top terms.
Paste an article, essay, or draft to estimate reading time and review the words that appear most often. The estimate uses a reading speed of 200 words per minute.
Keyword frequency is a writing aid, not an SEO score. Write naturally, match search intent, and avoid repeating phrases only to increase density.
Frequently asked questions
How is reading time calculated?
The tool divides the word count by 200 words per minute and rounds up to a whole minute.
What does keyword density mean?
It is the number of times a term appears divided by total words. Context and usefulness matter more than forcing a specific percentage.
Is my text uploaded or stored?
The calculation runs in your browser. This tool does not need to send your draft to an external analysis service.
