Why students use plagiarism checker by Litero AI?

Why Use a Plagiarism Checker?

One of the most feared things while you’re in school is passing a file through a plagiarism check because the consequences of the program flagging something as plagiarism can include a failing grade for that assignment or even the whole class. So yeah, it’s a big deal. But don’t worry! This is why plagiarism checkers exist. A plagiarism checker searches the internet and compares the text you’ve submitted to the search results it obtains. This allows it to highlight phrases, sentences, paragraphs, etc. that might be too similar. These programs are crucial for any student because they offer you an opportunity to check for any inconsistencies and see whether your paper, discussion post, project, proposal, etc. looks a lot like other documents online. Beyond normal checkers, AI plagiarism check programs take advantage of the power of AI and give you better, more efficient results. These ensure accurate reports that tell you exactly where you can find the text that looks like the one you submitted, giving you the chance to look at it and see what’s going on.

What Does It Mean If It Flags Something as Plagiarism?

The objective answer to this is that a sentence or phrase in your document is similar to another on the internet. However, this doesn’t necessarily mean you’ve plagiarized something. Plagiarism checkers are still programs, and they can make mistakes. Maybe the quote you include with perfect MLA format is what got flagged as plagiarism, but because it’s adequately included in your document, it becomes a simple glitch.

Gives You Plagiarism Levels

Plagiarism check programs don’t tend to categorize everything under the single umbrella of “plagiarism”. Instead, they classify matches accordingly. Programs usually classify them as “identical matches,” “minor changes,” or “paraphrased.” The first means that your text is exactly like something found online, the second means you changed a few words, and the last one means your text is similar to another source. It’s important to look at these categories because the program could have flagged something that was indeed identical or paraphrased but doesn’t have the necessary citation, meaning you need to go back and add them.

Helps You Manage Plagiarism

It’s perfectly possible that you meant to add a citation at the end of a sentence and then forgot. It happens! If you did plagiarize something, whether intentionally or otherwise, a plagiarism checker helps you by highlighting these sections and allowing you to fix them. This can save you time and stress in the future if you submit a file that has sentences you didn’t cite correctly.

Fixing Plagiarism

All plagiarism check programs are useful because you can fix problems while your document is still safe inside your computer and not in your professor’s email. The benefits of using an AI plagiarism check program include the ability to paraphrase something and asking the AI how to fix a sentence or expand an idea. These programs don’t work as secondary tools; instead, they work with you and your writing. The role they have depends on what you need and ask them to do, and they can become valuable tools for any student or anyone who regularly writes.

Also, we partner with GPTZero and Copyleaks to help students transition to AI-free and plagiarism-free work.
