What it really isCopyleaks — AI-powered plagiarism and AI-generated content detection platform for education, publishing, and enterprise.
Our takeCopyleaks is a dual-purpose scanner: it catches both traditional plagiarism and AI-generated text (ChatGPT, Claude, Gemini, and others) with reported 99%+ accuracy across 100+ languages.
Copyleaks' core market is academic integrity, LMS integrations, and enterprise content compliance. The listed $10/mo entry price is also slightly off; the actual Essential plan runs $8.99/mo for 100 pages.
Why we rate itCopyleaks stands out for combining AI detection and plagiarism checking under one roof with enterprise-grade LMS hooks — most competitors force you to choose one or pay for both separately.
The catchCosts scale fast: the free tier is tight at 10 pages, and moving from personal to team or institutional use quickly pushes into custom pricing territory.
API and bulk-volume contracts carry no public price.

  • LMS-integrated workflows (Canvas, Moodle, Blackboard, Google Classroom)

  • Budget-constrained individual students needing high page volumes
Trade-offs

Friction report

Trade-offs to know before signing up.

  1. Time to value
    Fast: free account created without a credit card; first scan runnable in under 2 minutes via paste or file upload.
  2. Scale breakpoint
    500+ pages/mo or multi-seat team use — Business plan limits bite and enterprise quotes introduce procurement friction.
  3. Walled garden
    Moderate: detailed reports and historical scan data live in-platform; exports exist (PDF/CSV) but full audit trails require staying subscribed.
Still a fit?
If none of these block you, start on the free plan.
