What to detect

PresetsWord-to-Word [Sciences]Rewrite [Arts]

'Text Rewrite' Detection Preset

This text comparison preset allows for a 'Lax Matching' - it is ideal to check for a suspected Text Rewrite. This preset works best for 'Arts' texts and documents alike

Preset for 'Word-to-Word Match'

It is also called 'exact sciences' preset - it allows Plagiarism Detector Text Comparison Engine to exactly match source with suspected copies, thus minimizing false positives

AI Text Detector

Plagiarism Detector has recently added our latest development - an AI detection engine that allows to detect a number of AIs: Chat GPT, Google Gemini, Hugging Chat and Bing Bard

UACE Module

UACE - stands for 'Unicode Anti-Cheating Engine'. This module does analytics to detect most commonly used cheating strategy that replaces Unicode symbols with 'alike' alternatives

Quotes and References Handling

Quoted text and URL references are recognised and reported separately, so properly cited text is not counted as plagiarism.

Fine-tuned Sensitivity

Set the minimal plagiarism section length, the merge distance and your own alert threshold %.

Automatic Language Detection

The language of every document is detected automatically.

Step 3 / 5

Select check type

SourcesGoogleBingPDASSciPap 75MFolderDocument pair

Global Internet Check

This is a standard - largest scope search for Plagiarism in the world wide web. Plagiarism Detector uses Google, Bing and Yahoo as its global search results providers. Over 4 billion sources are searched for copies!

PDAS Database Check

Plagiarism Detector Accumulator Server - your own database of documents to run Plagiarism Checks. You can easily add or remove documents from this Database. It works as a LAN accessed Server with multiple clients

Combined Check - Internet + Database

This comprises both previous search scopes - this setting allows Plagiarism Detector to check all the provided sources - global Internet and your custom Database. This is the most complete Plagiarism search

Sci-Pap Database Check

SciPap - stands for 'Scientific Papers Database', this exact Database was compiled by your web crawling harvester - an analytical search engine that crawls Internet for Scientific Papers

'Folder Check' Option

This allows to run a Plagiarism Check against a folder of Documents. This does not require any previous indexing, but is significantly slower than PDAS Database checks

Compare to a Single Document

This allows you to run a Check on a pair of documents. You just select the source Document and then use this exact option to select the other Document. This is a pair-wise check

Exclude and Include Lists

Sometime you need to avoid checking against a specific resource of a document to avoid false positive results or do just the opposite - to force Plagiarism Detector check a specific page

Offline Mode

No Internet? Check against your own PDAS server on the local network; it is detected automatically.

Frequently Asked Questions

What types of plagiarism can Plagiarism Detector find?

Plagiarism Detector identifies all major forms of plagiarism including direct copy-paste, paraphrased content, mosaic plagiarism, and AI-generated text. It uses five search engines (Google, Bing, Yahoo, DuckDuckGo, and the PDAS academic database) to scan over 4 billion online sources. The built-in UACE Anti-Cheating Engine specifically targets character substitution tricks that students use to fool basic checkers.

Does Plagiarism Detector include AI content detection?

Yes. Plagiarism Detector includes a built-in AI Content Detector that identifies text generated by ChatGPT, GPT-4, Claude, Gemini, and other large language models. The AI detection runs alongside plagiarism checks in a single scan, so you get both results without needing a separate tool or additional cost.

What file formats does Plagiarism Detector support?

Plagiarism Detector supports over 12 document formats including DOC, DOCX, PDF, TXT, RTF, ODT, HTML, PPT, and PPTX. You can also check content directly from Microsoft Word and PowerPoint using the built-in add-ins, or batch-process entire folders of mixed file types using the Folder Watch feature.

Can I compare two specific documents against each other?

Yes. The Document Pair Comparison feature allows you to check two specific files against each other for matching content. This works entirely offline without an Internet connection and supports all 12+ file formats. It is useful for teachers comparing student submissions or editors verifying original drafts against final versions.

What report formats does Plagiarism Detector generate?

Plagiarism Detector generates detailed Originality Reports that include a plagiarism percentage score, highlighted matching passages, clickable source URLs, an interactive similarity graph, and a color-coded document header summary. Reports can be exported as PDF files for archiving, sharing, or attaching to academic records.
