Processing rules and limitations

  • Order of operations

    Cleanup follows the tool's displayed pipeline, so sorting and duplicate handling can affect the final line order.

  • Duplicate comparison

    Case sensitivity and whitespace normalization influence whether two lines are considered equal.

  • No language rewriting

    The tool changes selected structure and spacing; it does not paraphrase, translate, or correct grammar.

Text is cleaned locally

The source, settings, and result remain in browser memory and are not sent to or stored on the server.

Frequently asked questions

Why were two similar lines not merged?

Their case or remaining whitespace may differ under the selected comparison settings.

Does sorting change duplicate results?

It can change output order, while duplicate detection follows the configured pipeline and comparison rules.

Can I undo a cleanup?

Keep the original input until you have checked the result; copied or replaced source text cannot be recovered by the site.
