Results are raw - scores, counts, sources, and matched text. Your agent interprets, aggregates, and explains.

​
The four levels

The default is narrow because a widely copied document can match hundreds of sources. Ask for detail to see which ones. Scores are percentages, 0–100 to one decimal place - 98.5.

​
Results, never the document

Results are the flagged parts - matches, AI content, AI phrases and Excluded text - never the document itself, which stays in Copyleaks. Nothing found is held back; every completed scan links to its report, Open this scan in Copyleaks.

​
Match types

Strongest first. The same labels your report and scan settings use.

​
Where matches come from

This Batch matches appear only when Cross-check documents is on, and count toward the score like any other match. If This Batch carries the whole score, check whether the same document was sent twice. Any source may also carry the AI Source Match tag, meaning that source is itself AI-generated. It is a tag on a source, never a source type.

​
AI results - two layers

AI content - passages identified as AI-written. AI phrases - specific phrases within that content. Phrases are always inside AI content, never a separate category. Each AI phrase carries a frequency: how many times more often that phrase appears in AI writing than in human writing. A phrase at 220x turns up 220 times more often in AI text. Higher means more distinctive of AI writing - it does not mean the passage is more likely to be AI.

​
Cheat Detection

Where a plagiarism scan found them, hidden characters, white ink and text manipulation come back as flagged spans with their exact text and position - in copyleaks_get_results and in document order from copyleaks_get_flagged_segments.

​
Excluded text is not Excluded sources

  • Excluded text - content your profile’s Exclusions left out of the score: references, quotes, citations, table of contents, headings, headers and footers, code comments.
  • Excluded sources - sources you removed from the score afterwards.
