Check work for plagiarism and AI
Upload a work to check it for plagiarism and for signs of AI use, and to fact-check it: whether the facts hold up and the calculations add up.
- AI check — free
- Facts, logic and calculations — also free
- Plagiarism — sources, percentages and highlighting right in the text
What you can check
Three independent checks. Order any one of them on its own, or all of them at once.
Plagiarism
A search for verbatim matches and paraphrase across every source we can reach, in an interface that is easy to read.
The price depends on length
AI check
An estimate of how likely it is that the text was generated by AI, with a confidence interval and an explanation of what points that way.
Free for work up to 100 pages
Logic and factual accuracy
We look your sources up in academic catalogs, search the text for contradictions and recompute the arithmetic in your calculations.
Free for work up to 100 pages
How a check works
Upload
DOCX, DOC, RTF, PDF or TXT. The file is kept in your account — you are the only one who can open it.
Choose the checks
Choose what to check — plagiarism, AI or logic. You see the price of each check and the total straight away.
Report
Each check runs on its own, and the results appear as they become ready: highlighting, sources and check depth.
Transparent and safe
Your file is protected
Your work is used only for the check and is stored under protection: it is never made public, and only you can open the file. You can delete the work together with its file at any time.
An estimate, not a verdict
Percentages are a probabilistic estimate, not proof of a violation. We always show the check depth and the margin of error. How to read the report
You are in control of the check
You order only the checks you need and see the price of each one before you pay. No hidden charges, no auto-renewals.

It is a probabilistic estimate, shown with the check depth and the margin of error — not proof of a violation. The final decision always rests with a person.
The file is kept in your account and is used only for the check. It is never made public, there is no link that opens it, and it never joins the database other works are compared against. You can delete the work together with its file at any time.
You decide what to check — plagiarism, AI or logic — and you see the price of each check and the total. You pay only for what you pick.
