Originality.ai のクイックスタートと実践のコツ

クイックスタート

  1. 1

    Scan one representative article first, then review its AI-detection and plagiarism findings as separate checks.

  2. 2

    Save or share the report link or PDF with an editor so everyone can review the same scan.

  3. 3

    Install the Chrome extension to check text directly from a supported browser workflow.

実践のコツ

Core tip: Keep the AI and plagiarism findings separate. Do inspect each result for the question it answers; don't treat an AI score as a similarity match or a plagiarism match as proof of AI use. When handing a report to an editor, include the original draft and review context rather than forwarding a score alone.

よくある質問

01Do AI and plagiarism checks answer the same question?

No. AI detection looks for patterns associated with generated text, while plagiarism checking looks for matching material. Review the two findings independently and verify relevant sources before deciding what a document needs.

02Can a scan identify who wrote each passage?

A scan report can summarize text findings, but it is not a complete record of authorship or editing history. Use drafts, contributor notes, and direct clarification when you need to understand how a passage was produced.

03What should I do if a human draft is flagged?

Treat the result as a prompt to review, not as a verdict. Check the highlighted text against the author's drafts and sources, then ask for context; do not assume that a flagged passage was generated or copied.
