Educators at every level face an increasingly complex challenge when it comes to verifying the originality of student work. The Internet has made information more accessible than ever, but it has also made copying easier. Add AI writing tools like ChatGPT and Gemini to the mix, and distinguishing genuine student effort from borrowed or generated content becomes a task that requires technological assistance.
A reliable plagiarism detection tool allows teachers to focus on what matters most — teaching and providing meaningful feedback — rather than spending hours manually searching for copied passages. By integrating plagiarism checking into your grading workflow, you can maintain academic integrity standards consistently across all your students while saving significant time.
When you have 30, 60, or even 150 student papers to review, efficiency is critical. Plagiarism Detector's Folder Watch feature lets you batch-process an entire folder of student submissions automatically. Simply place all the files in a designated folder, and the software checks them one by one without requiring manual intervention for each document.
The tool supports 12+ file formats — DOC, DOCX, PDF, RTF, PPT, PPTX, TXT, ODT, HTML, and more — so you can accept submissions in any format students use. Each document is checked against 4+ billion Internet sources via Google, Bing, Yahoo, and DuckDuckGo simultaneously, ensuring thorough coverage. The results are compiled into clear originality reports you can review at your own pace.
The rise of AI writing tools has created a new category of academic dishonesty that traditional plagiarism checkers cannot catch. Text generated by ChatGPT, Gemini, or HuggingChat will not match any existing online source — it is technically "original" — yet it is not the student's own work. This makes AI content detection an essential addition to any educator's toolkit.
Plagiarism Detector includes built-in AI content detection with 0.98 sensitivity, meaning it correctly identifies AI-generated text in 98% of cases. It analyzes the statistical patterns and linguistic fingerprints that distinguish human writing from machine-generated text. This runs alongside traditional plagiarism detection in a single scan, so you get a complete picture of each submission's originality.
Some students have learned to exploit weaknesses in basic plagiarism checkers by substituting characters from different Unicode scripts. For example, replacing the Latin letter "a" with a visually identical Cyrillic "а" can fool simple text-matching algorithms into thinking copied text is original. This technique is more common than most educators realize.
Plagiarism Detector's Unicode Anti-Cheating Engine (UACE) specifically targets this form of deception. It normalizes all Unicode characters before comparison, detecting substitutions from Cyrillic, Greek, and other scripts that look identical to Latin characters on screen. With UACE enabled, these character-swapping tricks are caught automatically, ensuring that no student can bypass detection through technical manipulation.

The Folder Watch feature is designed for educators who need to check large volumes of student work regularly. You configure a watched folder on your computer, and any document placed into that folder is automatically queued for plagiarism checking. This eliminates the repetitive process of opening, checking, and closing each file individually.
The batch processing system handles mixed file formats seamlessly — a folder containing Word documents, PDFs, and PowerPoint presentations is processed without any manual format conversion. Results are saved as individual reports that you can reference when grading or during academic integrity discussions with students. For departments with high volumes of submissions, this feature alone can save hours every week.
Plagiarism Detector includes add-ins for Microsoft Word and PowerPoint that integrate directly into the Office ribbon. This means you can check a document for plagiarism without leaving the application you are already working in. Open a student's Word submission, click the Plagiarism Detector button in the ribbon, and the check runs right there.
The PowerPoint add-in is particularly valuable for courses where students submit slide-based presentations. It extracts text from all slides and checks each one against Internet sources and the AI content detector. This Office integration fits naturally into the workflow most teachers already use, adding plagiarism detection without requiring you to learn a separate application or change your grading routine.
