First, it acts as a way of reminding students that their work will be checked for originality.
Second, it offers educators detailed originality reports that highlight matching text and assign an overall matching percentage.
Unfortunately, there is no safeassign plagiarism checker free access.
Students and educators who need to access SafeAssign have to do so through their learning management system.
Freelancers, создатели контента and other unregistered students who want a plagiarism checker safeassign free solution might need to use other alternative platforms.
SafeAssign generates an originality report that displays three color-coded match levels:
| Match Percentage | Color Code | Интерпретация |
| 0-15% | Green | Low match — acceptable |
| 16-40% | Yellow | Moderate match — review recommended |
| 41-100% | Red | High — Potential Plagiarism |
How SafeAssign’s Plagiarism Checker Works
SafeAssign’s plagiarism checker operates through a user-friendly web-based interface that is accessible to anybody who has registered with Blackboard.
The users just upload their documents or simply write down the text into the checker, and the system instantly starts analysis.
It is a process that takes place in a number of steps.
First, SafeAssign’s software splits the text that is submitted into parts and cross-checks them with a wide range of internet sources, academic publications, and files that have been scanned previously.
The tool applies a sophisticated matching technology to detect not only a match but also paraphrased materials and restructured sentences.
In a few minutes, SafeAssign produces a detailed report on the originality percentage and any similar areas.
In every flagged section, the source URL or reference would be provided and the user can confirm matches and make the required changes.
The system color-codes results based on similarity levels, making it easy to identify areas requiring attention.
Key Features of SafeAssign’s Plagiarism Checker
SafeAssign offers several features tailored to academic environments.
Некоторые из них включают:
- Database Coverage: The tool accesses ProQuest’s extensive academic database containing scholarly journals, books, and published papers. It also has an institutional archive of past submitted student work and is part of a worldwide database on scholarly articles submitted by institutions all over the world.
- Draft Check Option: Students have the option of sending drafts prior to final submission to check unintentional plagiarism. These draft checks are not added to the institutional database, enabling students to make amendments to their work according to the first evaluation.
- Blackboard Integration: Blackboard Learn can be smoothly integrated with SafeAssign to ensure that any task is safely assigned with one click. The originality report is presented directly in the grading interface with the submissions of the students.
- Detailed Matching Reports: Originality reports contain detailed information on individual matches, including the URL or document of the source and the percentage of overlap, and textual highlights within the context of the entire submission.
- Exclusivity: SafeAssign allows instructors to set up exclusion based on quoted textwork, bibliographic citation, or small matches as defined by a word count limit. This assists in minimizing false positives of duly referenced sources.
- Multi-File Format: SafeAssign supports a number of document formats, such as DOC, DOCX, PDF, TXT, RTF and HTML files with an upper limit of 10MB.
Is SafeAssign Accurate?
The question that any plagiarism detection tool has to answer is accuracy.
SafeAssign is different in terms of its performance and the sources of the original document.
SafeAssign is suitable for detecting traditional plagiarism within its database.
The instrument is dependable in detecting direct copying of academic journals listed in ProQuest and detecting duplicated student papers in institutional repositories.
Nonetheless, there are various influences on the overall performance of SafeAssign.
Materials that are paywalled or subscription-only journals that are not a part of ProQuest are not available through this tool, leaving plagiarized materials undetected due to a blind spot within it.
Also, SafeAssign faces the difficulty of advanced paraphrasing tools, where the material has been rephrased significantly without altering the original thoughts and arrangement.
There are also instances where the tool gives false positives due to properly cited quotations and references and these have to be manually checked by the instructors.
Above all, SafeAssign does not have specific AI detection features.
The classic plagiarism checker was made to identify similar words in the existing databases, however, the AI-generated content poses another threat since it is technically original and not present anywhere.
Such a shortcoming implies that the matching percentages on submissions by AI tend to be low irrespective of whether the submission is genuinely written by a student, a major deficiency in the modern academic integrity checking.
Below is a short test to evaluate SafeAssign’s real-world accuracy:
Тест и результат
To evaluate SafeAssign’s real-world accuracy, we conducted tests using a methodology inspired by ZDNet's benchmark for AI content detectors.
Our approach involved submitting different content types through SafeAssign and comparing results with our AI detector tool.
We created four test documents that contained approximately 500 words and covered the same general topic to maintain consistency:
- Human-written original content
- AI-generated content from ChatGPT (unmodified)
- AI-generated content processed through an AI humanizer
- content with intentional plagiarism from academic sources
The results reveal significant findings. SafeAssign successfully identified traditional plagiarism with high accuracy, flagging many of the words as intentionally plagiarized content.
However, the tool showed no meaningful difference in matching percentages between human-written content, raw AI-generated content, and AI-humanized content.
The low percentages all fall within the “acceptable” green zone according to SafeAssign’s classification system.
In contrast, our AI Detector correctly identified 98% of the raw AI-generated content as artificial, while showing 79% likely human detection for authentically human-written work.
Even after processing through our AI Humanizer tool, the content showed only 12% AI detection, a dramatic reduction from the original 98%.

These findings show that SafeAssign can work as per its intended use as a traditional plagiarism detector but cannot detect AI-generated works.
Since academic integrity issues are becoming more centered on the human/AI work separation, this drawback is a crucial vulnerability in the functionality of SafeAssign.
Our AI Detector, however, is one of the most effective tools to determine human and AI writing with a high accuracy of over 95% on testing.

To users who are worried about their content looking like it is indeed written by a human, our Детектор искусственного интеллекта и гуманизатор combination offers verification and rewrites capabilities.
The Detector identifies sections that trigger AI detection algorithms, while the Humanizer rewrites flagged portions to achieve a natural, human-like style that passes scrutiny from both AI detectors and human readers.
