With AI tools becoming more and more prevalent (and increasingly present in education), it’s important not to overly rely on them.
Assignments, projects, and courses often have clear guidelines on whether AI use is or is not permitted. So, it’s important for educators to be able to maintain transparency and identify potential AI use.
EssayGrader offers “effortless AI detection to preserve academic integrity.” So, as part of our AI detection review series, we tested the EssayGrader AI detection tool against the industry-leading Originality.ai AI Checker.

The Essaygrader AI detector is designed to help teachers identify whether or not a piece of content is AI-generated. For teachers, it aims to help them uphold academic integrity to prevent students from passing off AI-generated content as their own.
For students, it could also be helpful for checking their work before submission, to ensure they haven’t overly relied on AI tools during their work.
In addition to AI detection, the EssayGrader also offers other features built for teachers, including rubric libraries and custom rubrics for teachers.
It’s no secret that the use of AI content generation tools like ChatGPT, Claude, and Gemini has continued to rise in recent years. Ever since the launch of ChatGPT, more people have adopted AI across industries.
However, this increased adoption has also come with some drawbacks, most notably around concerns and challenges regarding AI usage within classrooms and potential plagiarism.
Therefore, tools like EssayGrader’s AI detector have also increased in popularity, with teachers wanting to maintain academic integrity in students' work, and conscientious students not wanting to overly rely on the new technology to complete their assignments.

However, the real question isn’t whether or not the EssayGrader AI detector is popular — it’s how effective it is.
To find out the answer, we put the EssayGrader tool to the test, highlighting whether the detector could spot fully AI-generated text and how well it performs compared to the Originality.ai industry-leading AI detector.
Step 1: To start, we created two unique prompts and pasted them directly into ChatGPT (ChatGPT 5), using the resulting content as our baseline test of AI text that both tools should identify as 100% AI-generated.
This produced 2 samples of academic AI text:
Step 2: Then, we took that content and pasted it word-for-word into each of the two detection tools to see whether the tools could detect the content as AI-generated.
