Frequently asked questions
Quick answers about how ClaudeSEO scores your writing.
How is the AI percentage calculated?
ClaudeSEO looks at patterns such as sentence rhythm, repeated phrasing, and stock transition words, and combines them into an estimate of how much of the text reads as machine-written.
Is the result 100% accurate?
No detector is. Treat the score as a guide for editing, not as proof of who wrote the text.
Does improving the text change my meaning?
The rewrite keeps your ideas and facts. It changes wording and flow, so read it through before you publish.
Will this help my SEO?
Clear, original writing tends to serve readers better, which is what search engines aim to reward. The tool does not guarantee rankings.
Is my text stored?
Pasted text is used only to produce your report. Check the privacy page for the full policy once it is published.
