Originality check
See how your draft reads — before a reviewer does.
Run an AI-detector preview on your own work, in the workspace, before you submit. It surfaces passages worth a second look so you can cite or rework them. It’s a preview to act on — not a promise about any detector’s score.
Beta opens this season — starting with students and researchers.
WHAT IT SHOWS YOU
An early read, at the passage level
Not a single score to obsess over, but specific sentences to review — with the context you need to decide what to do.
AI-detector preview
Get a read on how your draft looks to common AI-text detectors. It’s a signal to review, not a verdict — detectors are imperfect and you should treat them that way.
Passage-level detail
Findings point to the specific sentences worth a second look, with context, instead of a single opaque percentage.
Similarity preview — on the roadmap
A source-similarity check against published work is on the roadmap. Until it ships, the preview covers AI-detector signals; cite as you write and attribution takes care of itself.
What we won’t claim
No guarantees about any detector’s score
Detectors are probabilistic and frequently disagree with one another. Copyeditor’s preview helps you spot and fix issues early — uncited passages, close matches, prose worth rephrasing. It does not, and cannot honestly, guarantee that any third-party plagiarism or AI checker will return a particular result. Treat it as a signal to review, not a verdict.
FROM FLAG TO FIX
Every finding has a next step in the same workspace
Drawing on a source?
Cite it properly — one click adds the in-text citation and the reference entry — and, if needed, paraphrase it in your own words.
Your own phrasing flagged?
Review the context and decide. The preview is informational, so a flag on your own writing is a prompt, not a problem to panic over.
Questions about the originality check
Does this guarantee my paper will pass a plagiarism or AI checker?
No — and we won’t claim it does. Detectors are probabilistic and disagree with each other. The originality preview gives you an early read so you can fix issues before submitting; it is not a guarantee of any score on any third-party tool.
How is this different from the final check my institution runs?
Your institution may run its own similarity or detection software. The preview is a heads-up you control, on your own draft, before submission. It helps you catch uncited passages early; it doesn’t replace or predict an institutional result.
What should I do with a flagged passage?
Treat it as a prompt to review. If you’re drawing on a source, cite it and consider paraphrasing it in your own words. If it’s your own phrasing, you can usually leave it — the preview is informational.
Is it built into the document?
Yes. The preview runs on your live draft inside the workspace, so you don’t paste your text into a separate tool to check it.
Catch the issues early
while you can still fix them
The originality preview is part of the Copyeditor beta. We’re onboarding students and researchers first — apply and we’ll reach out as spots open.
