Your Documents

Add Word (.docx), PDF and text files with the Add button or in the step-by-step wizard. The list shows every document and the folder it comes from.

Main Window and Quick Check

One window for everything: start a Quick Check, follow every document's progress and open your reports. Your plan and the checks left are always in view.

Step-by-step Check Wizard

Three guided steps - add your documents, choose what to detect, pick the check type - and the check starts. It can open at every start-up.

Drag and Drop

Drop .docx, .pdf and .txt files on the main window to add them to the check.

Last Session Documents

The wizard reloads the documents of your previous session with one click.

Apple Silicon and Intel

One universal app, native on Apple silicon and Intel Macs, for macOS 13 Ventura and later. Signed and notarized by Apple.

Step 2 / 5

What to detect

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

Text Rewrite Detection - "Arts"

The recommended preset: finds paraphrased and reworded passages as well as exact copies.

Word-to-Word Detection - "Sciences"

Maximum exactness for technical and scientific texts: only word-for-word matches are reported.

AI Content Analysis

Highlights passages that look machine-written. The AI ring shows the analysis while the check runs, and the report gives the AI share next to the plagiarism level.

UACE - Unicode Anti-Cheating Engine

Catches letters swapped for look-alike symbols from other alphabets and hidden characters: it warns you above your threshold and normalizes the text before the check.

What Counts as Plagiarism

Set the longest allowed quotation and the shortest reported match in Settings, so properly cited text is not counted against the author.

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

Manual sensitivity sets the minimal reported plagiarism size; the report list adds your own alert threshold %.

Automatic Language Detection

The language of every document is detected automatically.

Step 3 / 5

Select check type

SourcesGoogleBingSciPap 75MFolderDocument pair

Internet Check

Searches the web with Google and Bing, downloads the matching pages and compares them with your document on your Mac. Our scientific-papers index is searched as well.

Scientific Papers Check - "SciPap"

Compares your document with our own index of 75 million scientific articles and academic papers.

Check Against a Folder

Compares your documents with every document in a folder on your Mac: earlier submissions, a course archive, your own drafts.

Compare Two Documents

Checks your document against a second document you choose and shows every passage they share.

Live Results

Sources appear in the list as they are found, and the distribution graph fills in while the check runs.

Faster Repeat Checks

Search results, page texts and AI results are cached, so checking a new version of a document is quicker. Every cache can be cleaned in Settings.

Your Text Stays on Your Mac

The Internet check sends only short search phrases. The scientific-papers check and AI detection need the document text, and both can be switched off.
