Will the tool keep the original capitalization and word order of the first occurrence?

Yes, the tool retains the first occurrence of each word exactly as it appears, including its original capitalization, and maintains the overall sequence of the remaining unique words.

Can I use this tool to remove duplicate words from a PDF or formatted document?

No, the tool only accepts plain text input. You would need to copy and paste the text content from your PDF or formatted document into the input box for processing.

Does the tool count word variations like 'run' and 'running' as duplicates?

No, the tool treats each distinct word form as unique. 'Run' and 'running' would both be kept in the output since they are spelled differently, even though they share a root meaning.

Is there a limit to how much text I can process at once?

The tool can handle substantial blocks of text, but very large documents may take longer to process. For best results, it is recommended to process text in manageable sections if you encounter performance issues.
