[toggle title=”What is the difference between PaperChecker and Turnitin?”]

PaperChecker is designed for students to check grammar, style, usage, mechanics, spelling and originality while Turnitin is used for instructors to check for originality and grammar, facilitate peer review and enable online grading of student’s written work. Both services search the same database content.

The main differences between the two services are two-fold: 1) Turnitin shows the actual source materials of unoriginal content whereas PaperChecker only shows potential unintended plagiarism without matching sources and 2) Turnitin papers are added to the student database of papers; PaperChecker papers are not added to the database.

[toggle title=”Why isn’t PaperChecker free?”]Many free services end up costing students much more than they think when they find that their paper has been harvested and resold to other students who take credit for their work. We are committed to our customers’ privacy and will not redistribute, share or resell papers submitted to the service.[/toggle]

[toggle title=”How many times can I submit a paper?”]A paper credit can only be submitted once for plagiarism and grammar checker. Any resubmission of a paper credit will only generate a new Originality Report. Paper credits allow 3 resubmissions for Originality Reports.[/toggle]

[toggle title=”How large can my document be? How many pages or words?”]A single paper can be up to 5,000 words—approximately 10 single spaced pages or 16-17 double spaced pages. If your paper is longer than that, it will be considered 2 or more papers, depending on the total number of pages. For each 5,000 words, you need to purchase an additional paper credit. Submitted documents cannot be greater than 20MB.[/toggle]

[toggle title=”How do I submit a paper?”]To submit a paper, go to “Submit Paper” page, click the “Choose File” button and select the document you want to submit. Then click the “Submit Document” button.[/toggle]

[toggle title=”How many times can I submit a paper?”]You can submit your paper once and then submit a revision of that paper three times. If your revised paper is substantially longer than the first submission, PaperChecker will not consider it a revision of the original paper and ask you if you would like to submit the revision as a new paper.[/toggle]

[toggle title=”How many times can I resubmit a paper?”]Each paper submitted to PaperChecker can be resubmitted 3 times. Resubmissions must be at least 70% similar to the original document. Resubmissions cannot be more than 150% the length of the original document.[/toggle]

[toggle title=”Why did the submission fail?”]There are a couple reasons why a submission may have failed. Password protected files cannot be processed by our system. Files larger than 20MB cannot be processed by our system. If your paper is larger than 20MB it may be because of large images contained in the file. To submit the text of a large file containing images use the cut and paste submission method in PaperChecker. The system cannot process image based pdfs.[/toggle]

[toggle title=”How do I submit another paper?”]To submit another paper, you need another paper credit. Once you have credits, to submit another paper, go to “Submit Paper” page, click the “Choose File” button and select the document you want to submit. Then click the “Submit Document” button.[/toggle]

[toggle title=”What if I’ve submitted my paper to Turnitin already?”]PaperChecker is intended to check papers for plagiarism that have not yet been submitted to Turnitin. If your paper has previously been submitted to Turnitin, it resides in the student paper database. In this situation, you should not use PaperChecker because the analysis will result in a very high number of matches, due to the paper being compared against itself. You will not be able to distinguish between these self-matches and those against other sources.[/toggle]

[toggle title=”What is PaperCheck’s refund policy?”]All PaperCheck credits purchased are non-refundable. But if you do not receive the results within 12 hours, PaperChecker will give back your payment. So, you get it free![/toggle]

Grammar Check

[toggles class=”grammar”]
[toggle title=”What is the e-rater® technology by ETS®?” class=”in”]PaperChecker has partnered with Educational Testing Service (ETS) to incorporate e-rater as part of the service.

[toggle title=”How does the e-rater technology by ETS work?”]The e-rater engine uses machine learning and natural language processing that has been developed over a decade of research to identify grammar errors in written work. The e-rater engine in PaperChecker is the same technology used for automated scoring in the written sections of the GRE® and TOEFL® standardised tests.[/toggle]
[toggle title=”How does the e-rater technology differ from grammar checking in Microsoft® Word?”]The e-rater technology feedback is more comprehensive, including additional categories of errors not found in MS Word, and allows for students to investigate and understand writing errors by linking to the Writer’s Handbook rather than automatically accepting or rejecting the marks as in Microsoft Word. The e-rater error feedback was designed specifically with student writing in mind.[/toggle]

Plagiarism Check

[toggles class=”plagiarism”]
[toggle title=”What is plagiarism?” class=”in”]

The definition of “plagiarise” according to the Oxford English Dictionary (2011) is:

  • “to take and use as one’s own (the thoughts, writings, or inventions of another person);”
  • “to copy (literary work or ideas) improperly or without acknowledgement; (occas.) to pass off as one’s own the thoughts or work of (another)”

  • “literary theft.”

[toggle title=”How do I avoid plagiarism?”]There are four main ways to avoid plagiarism which we detail in a series of blog posts:

  1. Build a Paper Trail
  2. Cite as You Write
  3. Give credits to Words and Ideas
  4. Use technology for Peace of Mind


[toggle title=”How does PaperChecker check for plagiarism?”]PaperChecker uses pattern recognition to match the contents of submitted essays against a massive repository of digital content. This technique is different than the text searches of popular search engines such as Google and Bing and produces fewer false positives than search technology designed for other purposes.[/toggle]

[toggle title=”What content is searched to identify matching text?”]PaperChecker searches and compares papers against a database of 45 billion current and archived web pages, 337 million student papers and 130 million periodicals and scholarly publications.[/toggle]

[toggle title=”Are essays added to the Turnitin database?”]No, files submitted to PaperChecker are not added to the Turnitin student database, or any other database.[/toggle]

[toggle title=”What does the percentage mean?”]The ‘Similarity Score’ shows how much of your paper matches content in the Turnitin database. There is no firm line between a ‘good’ or ‘bad’ score. The score is meant to be used as a guide rather than a judge of the paper. For example, a 500-word poem could have a Similarity Score of 1% but could contain the famous phrase “to be or not to be, that is the question”. Obviously, the poem would contain plagiarism but would deliver a very low Similarity Score.[/toggle]

[toggle title=”Can I use PaperChecker for my essay writing business?”]No. Commercial use of PaperChecker is not allowed by our Terms of Service. PaperChecker is intended for students who want to check their own work. It is prohibited to use PaperChecker for ghostwriting or other services that sell essays, papers, homework writing or other written work. Using PaperChecker for profit of business services like these will result in the deactivation of your account without refund. PaperChecker , in its sole discretion, may determine whether an account is commercial use.[/toggle]
