Our testing approach

Looking for the perfect plagiarism checker can be a real headache for students, but at AcademicHelp, we're all about tackling this challenge with enthusiasm! Our team is super keen on digging deep and uncovering the best solutions for students.

Here's a peek at our thorough testing approach:

  • 🕵️Mystery shopping: Just like students, we use the tools to see how they really work.

  • 📋 Checking features: We make sure these tools have lots of helpful features that are worth the cost.

  • 👍 Assessing user experience: It's important that these services are easy and convenient to use.

When it comes to the actual testing, our experts get creative. They wrote five different essays on “Characteristics of a Leader.” Each essay had a unique purpose to challenge the plagiarism checkers:

  1. The first essay was completely human-written, to give a baseline of original human work.

  2. Then, we used a direct copy from the internet for the second essay to see how well the services detect obvious plagiarism.

  3. For the third and fourth essays, we got a bit techy and used AI tools like ChatGPT and Quillbot to rewrite most of the content. Around 80% of these essays were AI-generated, testing the tools' ability to spot AI-written text.

  4. The final essay was a tricky one, where we changed every single character in the text. This was to see if the services could catch such a clever form of trickery.

This detailed and hands-on approach helps our team figure out which plagiarism checkers are the real deal for students.

FAQ

What is the free best plagiarism checker?

If you're looking for a top-notch plagiarism checker that won't cost you a dime, AHelp Plagiarism Checker is your best bet.

So, you've got some great options to keep your work plagiarism-free without spending any cash!

Do plagiarism checkers actually work?

Yep, you're right! Nowadays, most plagiarism checkers can quickly scan text, URLs, or documents in just a few minutes. But here's the thing – it's not just about finding a tool that works fast. The real challenge is getting accurate results. Sometimes you might need to double-check things yourself, especially with AI-generated text or papers that have been changed a lot. 

Does paraphrasing count as plagiarism?

It's a bit of a yes-and-no situation with paraphrasing. If you just switch up a few words in a sentence and don't say where you got it from, that's plagiarism. But if you change the wording and also mention the source, then you're in the clear – it's not plagiarism. The key thing to remember? Always include in-text citations in your papers. It's super important to give credit where it's due!
