What Teachers Should Look for in a Plagiarism Checker
When selecting a plagiarism detector for the classroom, teachers should look for the following:
- AI content detection capabilities. AI plagiarism is a key consideration, and AI detection tools can help professors check for AI. In 2024 alone, 86% of students reported using AI tools in their schoolwork.
- Accuracy. Although false positives can happen, a good plagiarism and originality detector should limit them as much as possible. Additionally, a plagiarism detector should not be the only measurement to establish academic standing.
- Ease of use. Teachers are busy, so a good tool should therefore enable them to check assignments quickly and easily.
- Detailed reports. Simply identifying whether or not an assignment has been plagiarized isn’t enough. A plagiarism checker should also highlight the location of potentially matching text and provide the source of the original content for easy verification.
- Affordability. With high schools and colleges using AI detectors for everything from plagiarism checks to research, choosing a budget-friendly tool is often essential.
By zeroing in on these factors, teachers should be able to find the best detection tool to fit their needs. Fortunately, there are several options out there.
What Is the Best Plagiarism Detector for Teachers?
Before we get into our top picks, it's important to note that what’s best for one teacher isn’t necessarily the perfect fit for another — educators have unique requirements across institutions, assignments, and courses.
So, with that in mind, here are our choices for the best plagiarism detectors for teachers.
1. Originality.ai: Best overall AI and plagiarism checker
With 46.9% of students using AI in college work, according to a study published in Frontiers in Education, and Statista reporting that 86% of students use AI, finding a tool with both top-notch plagiarism and AI detection capabilities is essential.
Originality.ai is therefore our overall best plagiarism checker for teachers as it offers one of the most accurate AI detection and plagiarism tools on the market today.
For educators, Originality.ai features:
- A plagiarism checker with up to 90% accuracy that can identify everything from global to complex forms of plagiarism (like patchwork plagiarism)
- Detailed reports that highlight the location of plagiarized text, with links to sources
- A Lite AI checker for teachers with 98% accuracy and an under 1% false positive rate
- The ability to check for AI in 15 languages
- Flexible pricing and the ability to add educators (team management)
- A free AI Detector Chrome Extension so teachers can watch students write, reducing the likelihood of false positives
Even better, it's easy to use. Simply paste a student’s text into the tool, hit “Scan” and Originality.ai will analyze and return results. Quick, easy, and accurate plagiarism and AI detection teachers can trust.
Note: Originality.ai is an excellent resource for identifying potential plagiarism occurring from content in Google search results. However, it doesn’t scan academic or institutional databases.
2. Turnitin: for LMS integration
Those working in education have likely heard of Turnitin, as it’s a common choice for academic plagiarism detection. In addition, like Originality.ai, Turnitin is also one of the AI detectors used by colleges and universities for research.
One of the most popular options for student plagiarism checks, Turnitin features:
- An Originality check to detect plagiarism, including AI writing and paraphrasing
- Similarity Reports that highlight the potentially duplicated text
- A Feedback Studio for educators to add comments to student work
- Integration with various Learning Management Systems (LMS)
However, there are limitations to Turnitin such as price. Turnitin is subscription-based and doesn’t share its pricing on its website, so it may not be the best option for individual teachers or smaller schools who only need it for limited or occasional checks. Learn more in our Turnitin review.
3. Grammarly: for basic plagiarism checks
Grammarly is a solid choice for teachers who need a more budget-friendly subscription option (unfortunately, pay-per-use isn’t an option here).
Already a trusted name in grammar checks, Grammarly has expanded its product offerings to include both AI and plagiarism detection tools.
With Grammarly, educators can:
- Detect instances of student plagiarism and AI writing, with references to sources
- Get a Grammarly Authorship breakdown of whether text has been typed by a human, copied from an online database, or generated by AI
- Generate text with AI prompts
- Access the grammar, plagiarism, and AI checkers for a monthly fee
If teachers already use Grammarly to check for student spelling and grammar errors, it can be convenient to incorporate its AI and plagiarism features into their routine. However, Grammarly isn’t the most accurate plagiarism detector on our list.
Originality.ai is better than Grammarly at identifying complex types of plagiarism like paraphrasing and patchwork plagiarism. Learn more in our Grammarly plagiarism checker review.

Frequently Asked Questions
Tools for conducting a plagiarism check between two documents online are important as it helps to ensure the originality and authenticity of written work. Plagiarism undermines the value of professional and educational institutions, as well as the integrity of the authors who write articles. By checking for plagiarism, you can ensure the work that you produce is original or properly attributed to the original author. This helps prevent the distribution of copied and misrepresented information.
Text comparison is the process of taking two or more pieces of text and comparing them to see if there are any similarities, differences and/or plagiarism. The objective of a text comparison is to see if one of the texts has been copied or paraphrased from another text. This text compare tool for plagiarism check between two documents has been built to help you streamline that process by finding the discrepancies with ease.
Text comparison tools work by analyzing and comparing the contents of two or more text documents to find similarities and differences between them. This is typically done by breaking the texts down into smaller units such as sentences or phrases, and then calculating a similarity score based on the number of identical or nearly identical units. The comparison may be based on the exact wording of the text, or it may take into account synonyms and other variations in language. The results of the comparison are usually presented in the form of a report or visual representation, highlighting the similarities and differences between the texts.
String comparison is a fundamental operation in text comparison tools that involves comparing two sequences of characters to determine if they are identical or not. This comparison can be done at the character level or at a higher level, such as the word or sentence level.
The most basic form of string comparison is the equality test, where the two strings are compared character by character and a Boolean result indicating whether they are equal or not is returned. More sophisticated string comparison algorithms use heuristics and statistical models to determine the similarity between two strings, even if they are not exactly the same. These algorithms often use techniques such as edit distance, which measures the minimum number of operations (such as insertions, deletions, and substitutions) required to transform one string into another.
Another common technique for string comparison is n-gram analysis, where the strings are divided into overlapping sequences of characters (n-grams) and the frequency of each n-gram is compared between the two strings. This allows for a more nuanced comparison that takes into account partial similarities, rather than just exact matches.
String comparison is a crucial component of text comparison tools, as it forms the basis for determining the similarities and differences between texts. The results of the string comparison can then be used to generate a report or visual representation of the similarities and differences between the texts.
Syntax highlighting is a feature of text editors and integrated development environments (IDEs) that helps to visually distinguish different elements of a code or markup language. It does this by coloring different elements of the code, such as keywords, variables, functions, and operators, based on a predefined set of rules.
The purpose of syntax highlighting is to make the code easier to read and understand, by drawing attention to the different elements and their structure. For example, keywords may be colored in a different hue to emphasize their importance, while comments or strings may be colored differently to distinguish them from the code itself. This helps to make the code more readable, reducing the cognitive load of the reader and making it easier to identify potential syntax errors.
With our tool it’s easy, just enter or upload some text, click on the button “Compare text” and the tool will automatically display the diff between the two texts.
Using text comparison tools is much easier, more efficient, and more reliable than proofreading a piece of text by hand. Eliminate the risk of human error by using a tool to detect and display the text difference within seconds.
We have support for the file extensions .pdf, .docx, .odt, .doc and .txt. You can also enter your text or copy and paste text to compare.
There is never any data saved by the tool, when you hit “Upload” we are just scanning the text and pasting it into our text area so with our text compare tool, no data ever enters our servers.
