1. Why Noplag plagiarism checker?

Whether you are looking for a product or a service, or trying to create one, quality and reasonable price – that’s an ideal relationship, whatever ideas, features, properties or criteria you are trying to marry in your mind. This should probably be also made into a law – as some people assume that high price is a definite guarantee of top quality (which does not always work), while others expect getting great stuff for free (almost never works). Would it make any sense to put lots of time, effort and material resources into creating a quality product, and then just giving it away? This is no different for creating an efficient and accurate plagiarism checker that is safe and easy to use. Noplag services come at a reasonable price, but there’s a special welcome offer for those who are new to our site and want to see how Noplag plagiarism scanner works. Up to 10 free checks at is that mini-Wonderland where “quality” and “free” hold hands and appear together at the same time – and a glimpse of the professional high quality plagiarism services we offer.

2. How Noplag plagiarism checker works?

You submit a document or text – drag&drop, copy&paste or upload (multiple file formats are supported) – and Noplag scanner analyzes it, seeking matches against the Web, Publications or Noplag database. You receive a detailed plagiarism report fast – this is one of the distinctive features that make Noplag so efficient and convenient.

3. Plagiarism report review.

A quality plagiarism report provides individual percentages for all matches found, and sources for each of those that are also links you can check and review. These are listed next to the block of text that shows highlighted sections representing any similarities detected. A superb quality plagiarism report also gives you a handy option of excluding quoted material, thus avoiding the main problem low-quality plagiarism checkers come with – confusing plagiarized and properly attributed content, mixing everything together for the user to painfully sort out. Yes, this means no more Cinderella work of sorting the lentils from the ashes – and that’s why a professional plagiarism checker is worth using.

Accurate checks at a reasonable price – is this possible? It is, if you aim at creating a product that meets the needs of a variety of users, not just the ones with a considerable budget and lots of documents to scan for plagiarism on a regular basis. That's why an innovative Noplag online service was created with maximum effectiveness in mind, based on advanced algorithms of checking your texts against the Internet, public repositories and Noplag extensive database of academic papers. It is very fast, as compared to other plagiarism scanners, and provides a detailed plagiarism report that you can send and share.
