Three Dedup Scopes

Full Text removes a word once it has appeared anywhere before. Per Sentence resets at each sentence boundary. Per Line treats every line independently.

Highlight View

Switch to Highlight mode to see exactly which words were removed — duplicates are struck through and faded red so you can review every change before copying.

All Languages

Unicode-aware tokenizer handles Arabic, English, Chinese, Japanese, Hebrew, Russian, and all other scripts. RTL/LTR toggle for correct reading direction.

Smart Options

Toggle case-insensitive matching, trim extra whitespace, and strip punctuation before deduplication — independently configurable for precise control over the output.

Duplicate Report

Every removed word appears as a chip with its total occurrence count. See which words were most overused at a glance — click any chip to copy it instantly.

Use as Input

Click "Use as Input" to push the cleaned output back into the editor for a second deduplication pass — great for iterative cleaning or chaining with other text tools.
