And, as such, this can, essentially, help you to determine whether the match is likely to be considered plagiarism or not. In other words, the AI plagiarism checkers app program works by comparing the texts with those found on different websites online, in a database list of books, etc.

As well as pdf document files, archives, offline text databases, and the like. Then, thereafter, the duplicate finder compares each word and phrase within your text against these sources. If there are words that match then it means that your text was taken from somewhere else without giving credit to the source author — the matched part (plagiarism) is highlighted for you.

This is what they usually scan:
  • Online Documents Content
  • Offline Documents Content
  • A Portable Document File (PDF)
  • Video Transcripts Content & Internet Journals
  • User Search Engine Results Page (SERP) Domains
  • Online Journals & Thesis Content Materials

How To Deal With Plagiarized Text

Correct Paraphrasing: Paraphrase the plagiarized text correctly. It is important to understand the core concept of the original text you want to paraphrase. Use different words or alter the sentence structure or simply write those plagiarized sentences in your own unique style or use the best paraphrasing tool of your choice.

Sources Citation: When you have borrowed a sufficient amount of text from the original source, it is best to cite it to avoid plagiarism. Use a specific citation style like APA, MLA, or Chicago while taking some idea or quote from the source.

References Quotation: For word-to-word similarities in the text, it is best to put quotation marks around it. Quoting is the best approach to avoiding plagiarism in all important lines that you want to add to your writing as it is.

Some Other Useful Keynotes:

Always remember, for webmasters and website owners, unique and innovative ideas that aren’t everywhere on the Digital Online Web are key to growing a website’s audience. For authors, minor similarities in books can often get you in trouble. Notwithstanding, plagiarism, whether intentional or not, can ruin an author’s career.

When it comes to learners, before submitting essays or assignments, students should check for plagiarism to avoid low grades. Similarly, as for freelance content writers and bloggers, taking ideas from here and there and spinning them into a post is plagiarism. Therefore, writers must always strive to create new web-based content ideas that are relevant to their work.

Final Words:

It is very important to avoid plagiarism — more so when it comes to academic writing. You can no longer use your own text after it is published. Instead, it should be paraphrased manually or with a good rephrasing tool. Otherwise, it will be considered self-plagiarism. Luckily, there are just so many best paraphrasing tools available out there for you to use.
