How to read the report
A percentage is not a verdict. It is an estimate of probability, and it still needs a person to review it.
Similarity report
The report shows how much of the text matched the sources we found — and exactly where those fragments sit in your work.
Metrics
- Originality (with citation credit)
- How much of the text matched no source at all. The “with citation” figure counts properly formatted quotations as your own text; the “without citation” figure does not.
- Verbatim matches
- A word-for-word match. The firmest signal there is: you can see the fragment in the text and open it in the source.
- Reworded
- The same passage with words shuffled or synonyms swapped in — the usual trace of raising uniqueness by hand.
- Paraphrase
- An idea retold in different words. Counted separately, because paraphrase on its own is not a violation; what matters is whether a citation sits next to it.
- Citation share
- How much of the text sits inside formatted quotations. When this is high, the work is assembled from other people’s words even if every reference is in place.
- Check depth
- How many sentences we managed to check. The fewer were checked, the wider the confidence interval next to the percentage.
Text with matches marked
In the full text of the work every fragment we found is highlighted in its own colour, and clicking it takes you to the source.
- verbatim match
- reworded
- paraphrase
- citation
Sources
Sources are grouped by type. The ones we could confirm only from a search-engine snippet are marked “needs review”: the page itself would not open.
- Web
- Academic paper
- Book
- Regulatory document
- needs review
Signs of attempts to bypass the check
The higher the value, the more signs the file shows of technical attempts to bypass the check.
AI signals report
This check estimates how much the text looks generated — fragment by fragment, and from the style of the work as a whole.
Probability of AI generation
The answer is an interval, not a single number. A narrow interval means the signals agree; a wide one means there is little text, or the text is uneven.
Fragment-by-fragment breakdown
The work is broken down fragment by fragment. What to look at is not the overall percentage but which paragraphs landed in “high probability”.
- High probability
- Medium
- Low
Rewrite probe
High similarity is a sign of AI generation: a model barely edits AI-written text.
False positives are to be expected: bureaucratic phrasing, boilerplate methodology sections and texts by non-native speakers all look equally flat to the model.
Logic and factual accuracy
This check looks for what a machine can actually verify: whether the sources you list exist, whether the work contradicts itself, whether the arithmetic adds up.
- Sources
- Logic
- Calculations
Summary
Findings are split by severity. “Serious” means a DOI that does not exist or a calculation that does not add up; “minor” means discrepancies in how an entry is written.
- Serious
- Moderate
- Minor
Sources
“Could not confirm” does not mean “invented”: Ukrainian books, standards and older articles are often simply absent from international catalogs. It is a reason to check the entry by hand, not a verdict.
- Confirmed (catalog or working link)
- Could not be confirmed in the catalogs
- Not checked automatically (books, standards)
What the report does not prove
- The originality figure depends on the check depth: the fewer sentences we check, the wider the confidence range.
- Our percentage is fundamentally not comparable with university systems (Unicheck, StrikePlagiarism) — different databases, different methods.
- A correct citation with a reference is not treated as plagiarism and is counted in the “with citation credit” figure.
- The estimate of AI signals is probabilistic. False positives are possible with formal, bureaucratic writing and with texts by non-native speakers.
- Sources confirmed only by a search snippet (we could not load the page) are marked “needs review”.
Every figure on this page appears in the report as soon as the check finishes — in the web version and in the PDF alike.
