FROM INPUT TO NEXT STEP
How to use this tool
Paste the plain text of a page, article, or draft answer. Separate paragraphs with a blank line.
Review the word count, average sentence length, and highlighted passages.
Edit the passages that could be clearer and run the check again. Copy or download the report to share with an editor.
Understanding your results
Readable copy helps visitors follow an explanation. Start with a direct answer, group related ideas, and keep necessary detail close to the claim it supports. Sentence and paragraph length can identify places to review, but shorter is not automatically better. Preserve technical precision and the context your audience needs.
PRACTICAL ANSWERS
Frequently asked questions
Does a readability score predict SEO or AI rankings?
No. Text length metrics cannot predict rankings, citations, or whether an answer engine will use a page. This checker shows concrete editing signals rather than assigning an AI visibility score.
What counts as a long sentence?
This tool flags sentences with more than 25 words for review. That is a transparent editorial threshold, not a rule every sentence must follow. Technical writing may need longer sentences.
How is reading time calculated?
Estimated reading time is the number of words divided by 200, rounded up to whole minutes for nonempty text. Actual reading speed depends on the reader, topic, and format.
Can I check an unpublished draft privately?
Yes. The text is processed in your browser and is not uploaded or stored by the tool. A report is saved only when you choose to download or copy it.
