The WriteSafe platform offers tools for checking copy for plagiarism or AI.
Its aim is to help users identify whether a text has potential instances of plagiarism in writing or whether AI-generated text was used, such as from AI tools like ChatGPT.
In this article, we focused on reviewing the tool’s ‘Check Plagiarism’ feature with samples of content from published blog posts, as well as more complex samples of patchwork plagiarism.
These are our findings.

WriteSafe is a free online plagiarism checker that lets students, content creators, or bloggers check their work for plagiarism and optionally AI.
The WriteSafe Plagiarism Checker is designed for anyone who wants to run a deep check on their content to make sure it isn’t plagiarizing from any online sources.
The tool takes quite some time to scan and display results, so if you’re looking for a plagiarism checker that works quickly, you may want to consider an alternative.
The tool is free to use for up to 1,500 words. During testing, there didn’t appear to be limits on the number of times you could use it, and no registration was required.
However, depending the tool did not always complete its scans in our testing.
For the purpose of this WriteSafe review, we put its plagiarism checker to the test, evaluating two directly copied and pasted text samples from blog posts and two examples of patchwork plagiarism to see how the tool worked compared to the Originality.ai plagiarism detector.
We divided the test into two parts:
Step 1: First, we took content samples from articles published on the Originality.ai blog.
Step 2: Next, we added content directly from the Originality.ai blog posts into the Originality.ai plagiarism checker and into the WriteSafe Plagiarism Checker. We then checked what percentage of plagiarism was reported by each tool.
We chose two text examples directly from the Originality.ai blog:
Step 3: For the second part of the test, we chose examples of patchwork plagiarism.
Patchwork plagiarism is an example of plagiarism that pulls from different sources. Because it pulls from a “patchwork” of different places, it can be harder for even advanced plagiarism checkers to detect.
Step 4: We then ran both samples through WriteSafe Plagiarism Checker and the Originality.ai Plagiarism Checker to compare results. Our results are shared below as screenshots and as a detailed chart showing what percentage of plagiarism was detected by each tool.

The WriteSafe plagiarism checker started out strong, detecting both samples from the published blog with 100% match.
However, when it faced the patchwork plagiarism, it timed out on both examples, leaving a continuous loading screen. This is a clear limitation of the tool, as it prevents users from identifying potential plagiarism.
In contrast, the Originality.ai plagiarism checker, meanwhile, provided plagiarism detection scores for each of the samples tested:

You can upload or paste blogs, articles, or essays to the plagiarism checker and check it for plagiarism, including blog content. Keep in mind that the plagiarism checker takes some time to detect and present a plagiarism report, and in some cases, it doesn’t finish loading at all.
The WriteSafe plagiarism checker works with any type of content up to 1500 words, including student essays. If you need to check student essays, however, we recommend using the Originality.ai plagiarism detector as it’s much faster, more thorough, and presents sources clearly so it’s easy to understand whether or not something was potentially plagiarized.
