Copyleaks AI Detector のクイックスタートと実践のコツ
クイックスタート
- 1
Scan a representative sample in the language you review, then note the detector's highlighted passages and overall findings.
- 2
Open AI Logic for a flagged passage and inspect its explanation before discussing the result with its author.
- 3
Connect the browser extension or LMS integration for recurring submission reviews.
実践のコツ
Core tip: Use AI Logic to inspect a reason, not to certify authorship. Do check the highlighted text and its context; don't treat an explanation as independent proof or assume every supported language behaves identically. For a high-stakes review, follow the same human review process you would use for any detector.
よくある質問
01Does AI Logic prove that a passage was generated?
No. AI Logic explains signals behind a flag, but an explanation is still part of a detector result rather than independent proof. Review the passage in context and consider other evidence before making a consequential decision.
02Can the detector assess text with mixed authorship?
The site describes detection of AI passages, but a flagged section cannot establish who contributed each sentence. Use passage findings to guide a closer review, then compare with drafts or ask contributors for context.
03Does support for many languages ensure equal results?
Language coverage does not by itself guarantee identical performance across languages or writing styles. Test representative material in the language you use and keep a human review step for important decisions.
