Why would I need the paraphrasing service?

There are a range of reasons why an author may require a paraphrasing service. Typically, the publisher, institution or journal to which the paper will be submitted stipulates a maximum acceptable limit of similarity (X%), above which the submission will be rejected. Therefore, it is essential for the author to ensure that prior to submission, this maximum plagiarism level has not been surpassed.

How does the paraphrasing service work?

First, the author submits the text as a .pdf or .docx document, indicating the maximum percentage of similarity allowed by the publisher, institution or journal to which the paper will be submitted. Typically, this will range between 1% and 15%. Next, the author will either a) provide a similarity report (e.g. Turnitin) for the editor to work from, or b) request that a report is generated through the iThenticate or Sribbr services, which employ the Turnitin technology to analyse your document and identify text strings that match previously published work. The plagiarism checker highlights the text that matches strings in its database and produces a .pdf report with the highlighted text and a final similarity score. Then, the fee is calculated and the author is informed. After the author agrees the fee, the highlighted text is paraphrased and the document is re-submitted to evaluate the new level of similarity and ensure that the required similarity score or lower has been achieved.

iThenticate is the most trusted plagiarism checker by the world’s top researchers, publishers, and scholars. It searches and compares papers against a database of 70+ billion current and archived web pages; 135 million open-access journal articles, books and conference papers; and 69 million pay-walled journal articles, books and conference papers.

The fee structure

The fee is based on £80 per 1,000 words paraphrased. For example, if you have a 3,500 word paper that has 20% similarity and you wish this to be reduced to 10% similarity, then 350 words will need to be paraphrased + a 20% allowance for surrounding words that are inevitably included = a fee of £33.60.

If you require an iThenticate report to be generated, the fee is an additional £75 for each document up to 25,000 words, or £225 for documents up to 75,000 words (5 revisions included). Another choice for a similarity report is Scribbr, with a fee of £40 for documents up to 7,500 words, £70 for documents up to 50,000 words, and £100 for documents over 50,000 words (3 revisions included). Note that the similarity reduction process requires a minimum of 3 revisions. Both iThenticate and Scribbr use the Turnitin database, with iThenticate recommended for journal article submissions.

Instant Quotation


No, your text will not be added to the Turnitin database, nor any other database. Your paper or text will be deleted from the iThenticate or Scribbr system, and only stored temporarily on our password protected and encrypted server.

The process duration depends upon the word count, but in most cases completion will be within 2-4 days.

Zero percent (0%) is occasionally possibly, but only in edge cases. Final similarity scores of between 1% and 4% are achievable, and are typically well within the parameters of acceptability.
