Paste your text. We search the web for your most distinctive sentences and compare any page that matches, phrase by phrase.
How it works
Picks the sharpest sentences
The sentences with the most uncommon wording make the best searches, so those go out as exact-phrase searches.
Compares phrase by phrase
Every page that comes back is fetched and compared in eight-word runs, so small edits do not hide a copy.
Shows the source
Each matching sentence links to the page it also appears on, with how much of your wording overlaps.
An example
A paragraph pasted from a supplier's product page into a blog draft.
Two sentences matched: both appear on the supplier's page, with 38% of the wording in common.
Rewrite the matching sentences or quote and link the source.
Questions
How does it search the web?
Your most distinctive sentences go to a search engine as exact phrases. Pages that come back are fetched and compared with your text in eight-word runs.
Why does it take half a minute?
Each search and each page fetch takes a few seconds. The check runs in the background and the result appears here when it is ready.
Is it as thorough as a paid checker?
It covers what search engines can find on the open web. It does not search paywalled journals or private databases.
Is my text stored?
No. It is held only while the check runs and the result is kept on our side for 15 minutes so this page can show it.
