About This Tool
This is a professional and user-friendly online text deduplication tool designed to help you quickly clean and organize large amounts of text data. It supports traditional "By Line" deduplication as well as a specialized "By Paragraph" mode (delimited by empty lines), perfect for processing articles or complex datasets. You can choose to preserve the original order to maintain context or sort results alphabetically. The tool provides real-time feedback with detailed statistics including line/paragraph counts and reduction percentages. Since all logic runs locally in your browser, your text content is never uploaded to any server.
