Copyscape overview
Decision checklist
- Buying consideration: Round additional word blocks up to the next 100 words. Premium API plagiarism checks use the same published search rate. Private Index additions have separate word-based fees; searching the private index and the web counts as separate searches. Copysentry is billed separately. The FAQ documents an AI detector, but its current price was not verified and the plagiarism rate must not be applied to it.
- Operational fit: Cloud / SaaS; support: Official help documentation and vendor contact channels; confirm response times and contractual support before purchase..
- Evidence context: Verified on vendor site, with facts checked 6 Oct 2026.

Check drafts before they become published problems
Copyscape Premium lets an editor search for matching wording before an article is published. That is a different workflow from the free URL checker, which is useful when a page already exists online. For a publisher receiving freelance drafts, checking the text before approval gives time to replace unattributed passages or clarify quotations.
Open the matched sources rather than relying only on a summary. Boilerplate, properly attributed quotations and licensed material can produce legitimate similarities. The publication date, licence and surrounding context matter when deciding what to change. A matching passage is evidence of shared wording, not automatic evidence of who copied whom.
Use batch, API and Private Index for different jobs
Batch searching helps review many pages, while the Premium API supports a repeatable checking step in a publishing pipeline. Keep track of retries and revisions because each search consumes prepaid balance. Word and PDF uploads are helpful for submissions that have not yet been added to a content management system.
Private Index allows comparisons against material you have added to your own index, including unpublished content. That can help an agency detect repeated passages across its client drafts. Indexing and searching have separate charges, and checking both the web and the private index counts as two searches rather than one combined free operation.
Separate plagiarism checks from monitoring and AI analysis
Copysentry is the ongoing monitoring service for selected published pages. Buying Premium search credit does not automatically turn monitoring on. Decide whether the problem is screening new work, watching existing pages for copies, or both, and budget for the corresponding service.
The official FAQ also describes AI-detection functionality, but that is distinct from source matching. Do not use the published plagiarism-search rate as an AI-detector quote. More fundamentally, neither a clean web search nor an AI probability establishes complete originality. Private, inaccessible or unindexed material can remain outside a web matching workflow, so combine the report with citations, editorial review and the writer’s explanation.

Copyscape FAQs
What does a 1,050-word Premium plagiarism check cost?
US$0.12: US$0.03 covers the first 200 words, and the remaining 850 words require nine additional 100-word blocks at US$0.01 each.
Can the free URL checker examine an unpublished draft?
The free workflow checks published pages. Use Premium text entry or supported document uploads to check a draft before it has a public URL.
Does Premium automatically monitor a page after checking it?
No. Copysentry is a separate monitoring subscription. A Premium search is a check at that point in time.
Does searching both Private Index and the web cost one search?
No. The official documentation treats those as separate searches. Adding material to Private Index also has its own word-based fee.
Can matching quoted text be treated as plagiarism automatically?
No. Review attribution, permissions and source context. Shared wording can be legitimate, and a match does not establish ownership or copying direction.
Does the three-cent starting price apply to the AI detector?
That published rate is for Premium plagiarism searches. The FAQ describes AI detection, but its current charge was not verified here; confirm it separately before budgeting.
