A percentage tells you how much matches. These checks tell you what is wrong, why, and how to fix it.
The report shows your own document page by page – same fonts, tables, code and pictures – with the highlights painted on.
Each reference is looked up in Crossref, OpenAlex and Google Books. References that do not exist – common with AI tools – are flagged.
Sentences are compared by meaning, so paraphrased text and text translated from another language are found too.
A ready-made APA citation for every source, missing in-text citations, and your progress since your last check.
Look-alike letters, invisible characters, white or tiny hidden text and s p a c e d words are found and undone before matching.
Every report has a Submission ID and QR code. Anyone can confirm online that it is genuine – without seeing your text.
Words are counted the way Microsoft Word counts them – for Word files and PDFs alike.
Program code is compared by its structure, and reused figures are found even when resized.

Turnitin-style reports, plus checks that catch what a similarity score alone misses.
Distinctive sentences are searched on many web engines and research databases at once (OpenAlex, Crossref, arXiv, PubMed, CORE, DOAJ …) – open-access full texts included.
Every stored paper is compared with later ones – a copy of a classmate's or last year's paper is found, even weeks later.
Sentences are compared by meaning, so reworded text is caught, not just exact copies.
Finds sentences translated from documents in other languages – e.g. Hindi or Spanish into English.
Compares code by its structure, so renamed variables and changed comments do not hide copying.
Figures and photos reused from other saved papers are found, even when resized. Logos are ignored.
Shows how much of the text is likely written by AI tools (with a detection provider set up).
Look-alike letters from other alphabets, invisible characters, s p a c e d letters and white or tiny hidden text are flagged – and neutralised before matching.
The PDF report shows your own document – same fonts, tables, pictures and code – with only the highlights and numbered sources added.
Download as Classic integrity report, a colourful Modern report with charts, or a framed Certificate with grade and seal.
Exclude quotes, the bibliography, cited text or small matches; remove a source with one click and add it back any time.
Compare your text with any source; see what is not cited, missing quotation marks or properly cited.
Words are counted exactly as Word does – for Word files, PDFs, text and more.
Every report has a Submission ID and QR code. Anyone can check online that it is genuine and when it was created.
A printable certificate with the submission ID, date and a SHA-256 fingerprint of the text.
Every reference is looked up in Crossref, OpenAlex and Google Books – made-up or wrong references (often from AI tools) are flagged.
In-text citations missing from the reference list, and references that are never cited.
A ready-made APA citation for each source to copy, and your progress since the last check.
Compares the writing style with the writer's earlier papers – a hint for ghost-written work.
Text reused from your own earlier papers is listed apart and not counted in the score.
Grammar and spelling suggestions for the whole document.
Class codes, due dates, resubmissions, bulk upload, submission comparison, rubrics, grades and feedback, CSV export.
Checks per day, grades, similarity by assignment and where matches come from – for admins, instructors and students.
Connect Moodle or your website: send documents, get scores, words, issues and the PDF in any design as JSON.
Keep data on this computer or an external hard disk, in MongoDB, or both – with several MongoDB accounts filled one after another.
A fair queue for busy moments; checks continue after a restart and reuse finished work when a file is sent again.
PDF (even scanned), Word, PowerPoint, Excel, OpenDocument, RTF, HTML, EPUB, pictures (OCR), code and text in any language.
Give a school or company a number of checks per day, month or year; its administrator shares them with instructors, instructors with students – and everyone sees who used how many.
Bot traps on every public form, lock-out after wrong passwords, limits on new accounts, throw-away emails refused and safe browser settings.
Checks marked extra are optional – tick them under “More checks” when you upload.
Enter the Submission ID printed on every page – or scan the report's QR code.
Yes – a free account, so nobody else can see your reports. You don't have to sign up first: enter your email and a password when you upload and the account is made for you. A class code is optional.
59 PDF designs in 8 styles – Classic, Modern, Certificate, Academic, Minimal, Executive, Infographic and Official letter – each in several colours. All show your original file with the matches highlighted.
Every page shows a Submission ID and the report has a QR code. On the Verify page anyone can enter the ID and see when the report was created and its score – never your text.
Yes. Word files are counted by Word itself; PDFs and other files with Word's rules (headers, footers and page numbers are left out).
PDF (including scanned PDFs with OCR), DOC, DOCX, ODT, RTF, PPTX, XLSX, ODP, ODS, HTML, EPUB, TXT, Markdown, CSV, source code and images. There is no size or word limit.
It is the share of your words that match other sources. Quotes and the bibliography are excluded by default. A–D grades: A ≤ 10%, B ≤ 40%, C ≤ 60%, D above 60%.
Reports can only be opened by registered users who are logged in – you see your own reports, your instructor sees your class's. You choose: Standard repository stores your paper so later copies of it are detected; No repository checks it without storing it.
Yes. Your organization gets an allowance – a number of checks per day, month or year. Its administrator shares it with instructors and instructors with their students; nobody can give away more than they have. Everyone sees who used how many checks, and can search, filter and export the list.
Yes. When you check the very same file again, your own earlier copy is not counted as a source – so the percentage only changes if new matching sources were found. If someone else hands in the same text, it is still found.
