Plagiarism Detector Vs Plagiarism Checker — Accuracy Test

Both tools are highly accurate in their work, but let’s test them practically to choose the best plagiarism checker.

Test # 1: Exact Plagiarism

First, we will copy the text directly from a site and paste it into both tools. For this purpose, we have added a small section of ScienceDirect’s article, “Research Aircraft”.

Plagiarism Detector’s Result:

SmallSEOTools’ Result:

We copied and pasted the entire thing, and both tools detected it correctly. In addition, they highlighted the sources from which the content was sourced, adding transparency to their process.

So, both are winners here.

Test # 2: Partial Plagiarism

For the second test, we will use the exact text but with a few changes. We will paraphrase some of its parts with the help of an online paraphrasing tool to make them unique while keeping the others the same. This test will help analyze whether the tools can accurately identify unique content.

Let’s give it a go:

Plagiarism Detector’s Result:

We had changed the last sections of the content, and the plagiarism detector picked them out as unique. However, it left some sentences undetected in the first few lines. Otherwise, the results are quite precise.

SmallSEOTools’ Result:

The SmallSEOTools plagiarism checker has also provided detailed results. The output is similar to plagiarismdetector.net, but a little more comprehensive. It has detected phrases that are still the same as the original text. Moreover, it has left clauses that seem like common knowledge.

Test # 3: Paraphrased Content

Now, we will add the paraphrased version of the exact text. This time, all the sections are tweaked, but they are not humanized. This will allow us to see if the results are precise or not.

Plagiarism Detector’s Result:

The plagiarism detector has returned a 10% plagiarism score with paraphrased content. However, some parts still resemble the original text. This report is still reliable, but we also have another tool, so we will test that one.

SmallSEOTools’ Result:

Here, the tool has precisely highlighted the areas that are still plagiarized. However, the parts where the wording, tone, or sentence structure is changed are not flagged. Thus, this report is quite accurate.
