Find repeated paragraphs in your text

Separate paragraphs with one or more blank lines. Single line breaks remain part of a paragraph. Empty paragraphs are ignored, and leading and trailing whitespace is trimmed before comparison. Paragraph positions start at 1.

By default, paragraphs must match exactly after trimming. Optionally ignore letter case or treat runs of spaces, tabs, and line breaks as a single space. This finds matching text, not similar wording or plagiarism.

The output keeps the first occurrence of each paragraph in its original order and spelling, trims its edges, and separates paragraphs with a blank line. Your input stays unchanged. Up to 1,000,000 characters are processed locally without uploads or storage.
