Copyscape is a tool that detects whether content appears elsewhere on the web so publishers, writers and site-owners can check originality or track content theft.

Overview

Copyscape is a web-based plagiarism and duplicate-content detection service. You can paste text or upload a document (in the Premium version) or enter a URL to check whether that content appears elsewhere online. It’s designed primarily for web-publishers, content marketers, SEO teams and anyone wanting to protect or check content originality.

When you publish content that’s been copied elsewhere (or your content is being scraped), you risk SEO penalties, brand reputation damage, duplicate-content issues, and lost value. Copyscape helps you:

  • verify that newly created content is unique before publishing;
  • detect when your existing content has been copied elsewhere; act proactively so you can protect your intellectual property or web traffic.

This is especially useful if you manage many articles, work with freelancers, or rely heavily on original content for SEO.

FAQ

Can I use Copyscape for commercial-use content checking?
Yes — you can use Premium or Copysentry to check content you own or are creating commercially. You’ll still need to manage the rights to your own content though; Copyscape doesn’t grant licences to content.
How many checks can I do per month?
There’s no fixed “monthly quota” for Premium — you pay per check/word, so your limit is your budget. For Copysentry, you pick the number of pages and frequency (weekly/daily).
Can I integrate Copyscape into my workflow or CMS?
Yes — there’s an API for Premium that supports text or URL checks, JSON/XML responses, and you can build automation into your publishing workflow.
Does Copyscape detect content generated by AI?
Copyscape detects duplicate or similar text across the web but is not primarily an “AI-content detector.” If the generated content is largely novel, it may not flag it. You’ll need to use it as part of a broader originality check process.
What kind of support is available?
There’s a knowledge base and FAQs. Premium users can contact support, but it is more self-serve than full enterprise-SLA.
What’s the difference between the free and paid versions?
The free version allows URL-based checks of web pages only (limited). Paid (Premium) allows text uploads/pastes, more flexible workflows, API access and larger batch checking.
What happens if I publish content and then someone copies it — can Copyscape monitor that?
Yes — that’s the purpose of Copysentry. You choose pages to monitor. The service scans the web and alerts you when copies appear, so you can act.
