About the Remove Duplicate Words

Each word is kept the first time it appears and removed afterwards. Punctuation and line breaks stay in place, so the shape of the text is recognisable even though it no longer reads as prose.

This is mainly used to reduce a keyword list or a tag string down to its distinct terms.

Is it free, and do I need an account?

Yes, it is free, and there is no account, no sign-up and no watermark on the result. The project is funded by optional donations.
