    Rewrite a pasted draft with one bounded AI editorial response plus local scoring and source checks. Returns the safest source-preserving edit and exact before and after writing scores. If a writing target is missed, the edit still comes back with a clear review warning. Use it to improve writing quality, never to hide authorship or evade a disclosure requirement. Try and MCP use our hosted Zero Slop agent harness; results and speed may differ across Codex, Claude Code, Cowork, ChatGPT Work, and other hosts or skills.

Zero Slop is installed about 1,600 times a week on npm.

Find AI-sounding tells and slop in your writing.

Zero Slop finds slop- stock phrasing, mechanical rhythm, vague claims, and canned formatting in writing. Your existing AI assistant edits the draft; local checks guard its names, numbers, links, quotations, code, tables, and paths.

The scorer rates that draft 99.3/100 and flags four phrases: “We're thrilled to,” “leveraged,” “cutting-edge,” and “seamless.”

The rewrite, limited to the draft's stated claims:

We used machine learning to reduce onboarding setup time by 40%.

Writing score: 9.5/100  [clear]
  Flagged phrases : 0 across 10 words

The rewrite retains the draft's stated result. See four complete, reproducible pairs in examples/.

Use it for launch posts, changelogs, emails, research summaries, or batch checks. Scores describe writing patterns, not authorship.
