Does the tool treat uppercase and lowercase words as different?
No. It analyzes words case-insensitively, so 'SEO' and 'seo' are treated as the same word for counting.
Can I ignore common words like 'the' and 'and'?
Yes. Enable stop-word exclusion to remove common connector words from duplicate matching.
What does minimum repetition mean?
It is the smallest count a word must reach before the tool lists it as a duplicate in the report.
Does this tool detect duplicate sentences too?
No. It focuses on repeated single words. Sentence-level duplication would require a separate checker.
