To help you separate the best from the rest, this guide will break down how to choose the best online plagiarism checker.

Key Takeaways (TL;DR)

  1. Prioritize a highly accurate tool
  2. Make sure it can handle complex plagiarism types
  3. Ensure support is there when you need it
  4. Look for pricing and features that meet your needs
  5. Consider user reviews

What Is a Plagiarism Checker?

Before we get into what to look for, let’s clarify what we’re talking about here. What exactly is a plagiarism checker, anyway?

A plagiarism checker is a tool that scans a piece of writing, compares it to existing texts, and flags any similarities or duplicate content. In other words, it does just what its name suggests: checks for plagiarism.

When you consider some of the serious consequences of plagiarism, you don’t want to rely on guesswork — you want a tool backed by real data and testing.

How do plagiarism checkers work?

So, then how do plagiarism checkers work? Although they generally follow a similar process to the one outlined above (scan, compare, and flag), how exactly these tools work often depends on their make and model. 

Plagiarism checkers can work differently in terms of:

  • Where they scan. You can find tools that scan the web, academic databases, or even ones that look for duplicate content (learn about the different types of plagiarism detection).
  • What they detect. Some only look for exact text matches, while others also address paraphrasing and other types of plagiarism.
  • Whether they include AI detection. Some tools (like Originality.ai) also offer AI checkers that check for AI-generated text.

With so many potential differences between tools, it’s important to check each plagiarism detector you’re considering to learn about its detection methods.

Let’s take a closer look at Originality.ai.

Plagiarism detection at Originality.ai

Originality.ai’s web-based plagiarism checker breaks down a text into chunks and compares it against Google’s search engine results. 

So, if someone plagiarizes something you can find in Google’s search engine results pages (SERPs), you can use Originality.ai’s patented tools to identify it.

Once the Originality.ai plagiarism checker finishes its analysis, it produces a detailed report of its findings, including:

  • A plagiarism score showing a match score
  • Highlights on the matched phrases for easy identification in the document
  • The URLs of the websites with the matching text, so you can verify the sources

How to Choose the Best Online Plagiarism Checker

If you really want the best of the best, here’s a guide on how to choose the best online plagiarism checker.

1. Prioritize a tool with high accuracy

Plagiarism detection accuracy is a top consideration when looking for an online plagiarism checker.

However, not every plagiarism checker provides studies or analyses on the efficacy of its tool. So, look for a tool that advertises high accuracy and has the data to back it up.

Take Originality.ai, for example. Originality.ai not only offers a plagiarism checker with up to 90% accuracy, but we also evaluate it against other tools. Check out studies like our Grammarly plagiarism checker review and Copyscape plagiarism checker review to see how they stack up. 

Then, Originality.ai also offers the most accurate AI Checker, with a Turbo model (99%+ accuracy) and a Lite model (98% accuracy). We also offer insights into AI detection accuracy with our AI Detector Accuracy Study and a Meta-Analysis of third-party AI detection studies

2. Make sure it can handle complex types of plagiarism

Finding a highly accurate plagiarism detector with supporting evidence is great, but make sure you really look at the details before considering it further. It may accurately identify global plagiarism, but what about paraphrasing or patchwork plagiarism?

Fortunately, it is possible to find tools that can accurately identify multiple types of plagiarism, like Originality.ai.

Originality.ai’s plagiarism checker not only detects direct copy-and-paste plagiarism but also identifies global, patchwork, and paraphrase plagiarism.

3. Ensure support is there when you need it

Your next consideration should be: what happens if you need to reach out to support?

A plagiarism checker with a good customer support team behind it is critical for efficient workflow. To find one that’ll be there for you when you need it, look for signs like:

  • Responsive email support
  • Help articles
  • In-app chat

Originality.ai offers an exceptional customer support team. You can reach out and contact us or browse our Helpdesk articles and guides for more information.

4. Look for pricing and features that meet your needs

Next up on our list of considerations is pricing and features. 

Some platforms can be costly for individual users or small teams. So, when you’re looking for the best plagiarism checker it’s essential to consider pricing as well as features.

Let’s take a closer look:

Pricing

Your first step here is to evaluate pricing models. Plagiarism checkers often offer one or more of the following:

  • Pay-as-you-go pricing
  • Monthly subscriptions for individuals and small teams
  • Enterprise plans for agencies and publishers

If you can find a tool that offers all three, even better. When a company provides flexible pricing options like Originality.ai, it makes it easier to scale your plagiarism detection needs accordingly. For more information, check out Originality.ai’s pricing.

Features

Once you find a tool that fits your budget, the next step is to assess whether it fits your needs. Here are a few features to consider:

  • Detailed, shareable plagiarism reports to prove the authenticity of writing
  • A user-friendly interface that’s easy to use and access across devices
  • Access to integrations to check a writer’s work

Originality.ai’s plans give you access to a complete patented toolkit. In addition to the plagiarism checker, Originality.ai’s suite of tools includes:

If that isn’t enough, Originality.ai also offers a free Chrome extension, a WordPress plugin, and a site scanner that checks entire websites for AI.

 Learn more in our articles: new and improved web scanner and updated Chrome extension.

5. Consider user reviews

If you only evaluate plagiarism detectors by what you find on their websites, you’re not getting the complete picture. 

User reviews and feedback are critical to the research process, as they tell you what the tool’s accuracy, support, features, and more actually look like in practice.

One of the best places to look for user reviews of plagiarism checkers is Trustpilot. See what people have to say about our products and services in Originality.ai’s customer testimonials.

Why Finding the Best Plagiarism Detector Matters

With so many things to consider, finding the best plagiarism checker may seem overwhelming. However, it’s important for those in both professional and academic positions, including:

  • Marketers. Duplicate content can negatively impact search engine rankings and brand reputation.
  • Educators. Students need to submit original work to maintain academic integrity.
  • Content creators/bloggers. Plagiarism detection can help safeguard intellectual property and ensure unique content.

You can even find checkers tailored to your position. For example, Originality.ai offers a Lite AI detection model for teachers alongside its plagiarism tool. Learn more about Originality.ai’s AI detector for education.

Frequently Asked Questions

Do I have to fill out the entire form?

No, that’s one of the benefits, only fill out the areas which you think will be relevant to the prompts you require.

Why is the English so poor for some prompts?

When making the tool we had to make each prompt as general as possible to be able to include every kind of input. Not to worry though ChatGPT is smart and will still understand the prompt.

Frequently Asked Questions

Why is it important to check for plagiarism?

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.

What is Text Comparison?

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.

How do Text Comparison Tools Work?

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.

What is Syntax Highlighting?

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.

How Can I Conduct a Plagiarism Check between Two Documents Online?

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.

What Are the Benefits of Using a Text Compare Tool?

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.

What Files Can You Inspect with This Text Compare Tool?

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.

Will My Data Be Shared?

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.
