For writers
Check an article, a blog post or web copy before you publish it
Paste a draft, up to 2,000 words. The report shows which sentences already exist on the web and where, which quotations are recognised as such, and which paragraphs carry indicators of machine-generated text. Writers, editors and content teams use it to review a draft before it goes to a client or a publisher.
What you can check
- Articles and long-form pieces
- Blog posts and newsletters
- Web copy and landing pages
- Reports and white papers
- Ghostwritten and commissioned drafts
- Translations and adaptations
What you get
Each passage that matches a web page or a scholarly record is highlighted and linked, with the share of your text it covers. Duplicate copy, unattributed borrowing and recycled boilerplate show up with the page behind them.
Text inside quotation marks or accompanied by a citation marker is reported as a quotation, not as overlap, when the engine recognises it. The share of quoted text is shown separately.
Paragraphs with features often seen in machine-generated text are listed with their score, so that an editor can ask for a revision of a specific passage rather than judge the whole piece.
How to read the report
Overlap is a list of places to look, not a score to pass
Product names, standard phrasing and widely repeated facts match many pages. Open each source and decide whether the passage needs attribution, a rewrite, or nothing.
Coverage is limited to open pages and records
Pages behind paywalls or logins, and publishers’ closed full-text collections, are not searched. A clean result means no match was found in what is open, not that the text is unique everywhere.
AI indicators are not a verdict on the author
Template-driven copy, listicles and text edited for simplicity receive more indicators than average. The report lists the passages so that they can be revised; it does not say whether a tool was used.
What to do with the sources found
- Attribute or rewrite. A matched passage that is not a recognised quotation needs quotation marks and a link to the source, or a rewrite. For commissioned work, keep the report link with the draft as a record of the check.
- Check the facts behind the matches. Where a sentence matches several pages, the claim may be circulating without a primary source. Trace it to the original and cite that.
- Revise flagged paragraphs. Replace generic transitions and repeated sentence patterns with specific detail, examples and the writer’s own position.
- Verify any references you cite. If the piece cites studies with DOIs, the reference check reports entries that could not be found, so that a wrong or invented citation does not reach the reader.
