Keep the focused metric for the task at hand, then use the shared dashboard to cross-check counts, lexical diversity, reading time and frequent terms without uploading the text.

How to use this Duplicate Paragraph Finder

Paste multi-paragraph text, choose normalization rules, and review repeated paragraph groups with their paragraph positions.

What the result means

Paragraphs are separated by blank lines. Formatting-only differences can be normalized, but rewritten or semantically similar paragraphs are intentionally not labeled duplicates.
