Plagium Announces Deep Search

The Plagium Team is happy to announce the introduction of its Deep Search capability, which will enable Plagium users to compare large documents against the Web.  Deep Search breaks up the entered document into segments according to grammatical and word use rule.  A Web search is performed on these segments.  As the search results return, the results are compiled to determine where in the retrieved document text may match the original.  The displayed results show how the original text generally matches what is on the Web, as well as a paragraph-by-paragraph breakdown of the original text against retrieved Web documents.

Deep Search requires the establishment of a Plagium account, and the purchase of “credits” that entitle the user to specific volumes of text to be searched.  The pricing is as follows:
1 US $ for 100,000 characters
2 US $ for 200,000 characters
10 US $ for 1,100,000 characters

Payments are accepted through PayPal. Credits are good for one year.

For our occasional users that use less text volume, the Plagium remains available as a free service through use of the “Quick Search” button.


  1. I bought plagium credit worth U.S. $ 10, but when I try to use the service opens a window where it says I have exhausted the number of entries is mine by day. Could you please explain why this problem occurs.

  2. Hello Margarita:

    Thank you for your feedback.

    You indeed bought deep search credit with Plagium.

    You can click on the "Deep Search" button to perform your deep search.

    The Quick Search remains free, but its use is limited to 25 searches a day.

    Please do not hesitate to write us if you have other questions.

  3. I just bought a credit worth 10 USD and tried to make a deep search using a URL to a text file containing appr. 540.000 characters. I received a message that my file is too big and should try with smaller file. I checked my account and it shows me 15.000 free characters for deep search. It confuses me as I thought I had 1.100.000 characters to search and also I thought I can put it into the checker in one.

  4. Hello András:
    We checked your account, and you have been credited the 1100000 characters.
    However each search must be less than 25 000 characters.
    Please write us directly to our email: info(at) if you still have questions or issues.

  5. Thanks for the answer, yes, I see the credit now.

  6. Do you guys offer a 30 day money back guarantee on this, in case of an unsatisfied customer?
