What is a Plagiarism Checker?
A plagiarism checker is a specialized tool that helps writers, students, and researchers verify the originality of written texts. The tool analyzes the input text by splitting it into individual sentences, then searches each sentence in search engines like Google to detect any matches with content published online. This process helps ensure that the content you present is original and free from unauthorized copying.
This plagiarism detection tool features several unique characteristics. First, it fully supports the Arabic language with right-to-left text direction, a rare feature in free checking tools. Second, the tool works entirely within the browser without sending your data to any external server, ensuring complete privacy for your texts. Third, it provides advanced N-gram analysis that reveals patterns of repeated phrases that may indicate copying. Finally, it displays comprehensive text statistics including readability score, vocabulary richness, and academic text level assessment.
Whether you are a student preparing a university research paper, a content writer wanting to ensure article originality, or a professor reviewing student papers, this free tool will help you count words and analyze your texts accurately while detecting any potential similarity with other sources. Try it now and get an instant detailed report on your content originality percentage.
How to Use the Plagiarism Checker
1 Enter the Text to Check
Copy text from any source (Word document, academic research, article, web page) and paste it in the text box above. The tool supports all languages including Arabic and English, and automatically detects text direction. It is recommended to enter texts containing at least two sentences for effective and accurate checking results. You can also use the "Sample" button to test the tool before checking your own texts.
2 Click the Check Plagiarism Button
After pasting the text, click the green "Check Plagiarism" button. The tool will split the text into sentences and analyze each sentence individually. For each sentence, a Google search link is generated that you can click to see matching results. Very short sentences (less than 5 words) and common phrases are automatically classified as original content to reduce false alerts.
3 Review Check Results and Analysis
After checking, results appear in a clear visual format. Original sentences appear in green, while suspected sentences appear in yellow and you can click them to search on Google. The similarity percentage appears in a colored circular indicator (green = safe, yellow = warning, red = danger). Also use the "N-gram Analysis" button to discover repeated patterns and the "Text Statistics" button for comprehensive analysis including readability score and text level.
4 Improve Your Content Based on Results
If you find suspected sentences, rephrase them in your own style while preserving the original meaning. Use different synonyms and change sentence structure. If you are quoting directly, place the text in quotation marks and cite the source. The goal is to reach a similarity percentage below 15-20% for academic research. You can use the word counter to monitor text length during rephrasing.
Why Do You Need Plagiarism Checking?
For Students and Academic Researchers
Students in Saudi and Arab universities need to check their research papers and essays before submission. Most universities require a similarity rate below 20% in academic research. Plagiarism is considered a serious violation that may lead to failure or expulsion. Use this plagiarism checker as a preventive step to ensure your research originality before submission. Master's and doctoral theses require a higher level of originality, so early checking saves you time and effort in rewriting later.
For Content Writers and Bloggers
Duplicate content significantly harms your website ranking in search engines. Google penalizes sites that publish copied content by lowering their ranking or even removing them from search results. Professional content writers use plagiarism checkers to ensure their articles are unique before publishing. Even if you write content yourself, some common phrases may match existing content. Pre-checking protects you from SEO penalties, maintains your website reputation, and increases visitor trust in your content.
For Teachers and University Professors
Professors and teachers need quick tools to verify the originality of submitted assignments and research papers. The plagiarism checker allows them to quickly check student texts and identify copied parts. This helps maintain academic integrity and encourages students to write creatively and originally. Teachers can also share the tool with their students to teach them how to self-check their texts and promote a culture of academic honesty from early educational stages.
For Publishers and Quality Managers
Publishing houses, scientific journals, and news websites need to ensure published content is original and not copied. Plagiarism checking is an essential part of quality review before publishing. Copying others' content without permission may expose the organization to legal issues related to intellectual property rights. Using a plagiarism detection tool protects the organization from legal risks and maintains its credibility with readers, subscribers, and search engines alike.
Tips for Writing Original Content
1. Understand the Topic Before Writing
Read multiple sources about the topic and understand the main ideas before starting to write. When you understand the topic deeply, you can explain it in your own style without needing to copy. Take notes in your own words and use them as reference while writing. This ensures content originality and gives it your personal touch.
2. Master the Art of Paraphrasing
Paraphrasing is not just replacing words with synonyms. Good paraphrasing means changing the entire sentence structure while preserving meaning. Use different grammatical constructions, change the order of ideas, and connect sentences in a new way. Use the word counter to compare original text length with the paraphrased version.
3. Document Your Sources Accurately
When directly quoting, place the text in quotation marks and cite the full source (author, title, year, page). Documented citation is not plagiarism but a proper academic practice that strengthens your research credibility. Use the citation system required by your university (APA, MLA, Harvard) and be consistent in applying it.
4. Review Your Text Before Submission
Before submitting research or publishing an article, check it with a plagiarism detection tool. Review suspected sentences and rephrase them. Ensure similarity percentage is below the required threshold. Ask a colleague to review the text for any similarities you may have missed. Improve your typing speed to save more time for review and improvement.
