How Clean pasted text works

Clean pasted text removes supported hidden characters inside a small set of English words. It skips recognized code, URLs, quoted text and non-English text, and preserves uncertain cases. In the browser, cleanup runs on your device and keeps your original.

This cleanup does not verify whether a statistical watermark is present or removed.

Choose Check and edit when you want to revise the wording.

Compare the edit with your original. Source-detail checks track names, numbers, quotations and links; they do not verify factual accuracy or guarantee unchanged meaning. How to review an edit.

A score of 25 is Zero Slop’s review threshold. Lower is better. The score describes the writing, not who wrote it.

These are reference samples; other writing can score outside these ranges. Scoring method.

How we check the rewrite

The scoring tool checks the rewrite once on your device. If it still finds problems, it shows a warning rather than calling the AI again. Review the names, numbers, quotes and links it found in both versions.

Use the installed skill to edit with your own AI assistant. It follows the same eight editorial steps and runs local checks. Install it in one command.

Editing with a browser agent

Experimental WebMCP support lets a compatible browser agent open the local/live editor, submit a draft, and read its checked result. Live edits require an on-page confirmation. The controls on this page work without WebMCP.

Browser compatibility

Try requires a browser with WebAssembly. We tested local scoring and pasted-text cleanup on desktop and checked Try on mobile.
