AI Checker or Copyleaks — which fits you?
Copyleaks is enterprise-focused — its product is sold through sales teams, requires onboarding calls for paid tiers, and is deeply integrated with LMS platforms in higher education. The product is solid but priced and packaged for institutional buyers. AI Checker is the focused alternative: AI detection done well, free tier for individuals, paid tiers that scale linearly without sales gatekeeping. For institutional buyers who need full Copyleaks features (combined plagiarism + AI detection, established LMS integrations, compliance audit trails), Copyleaks is still the right choice. For everyone else — content teams, individual educators, freelance editors, developers integrating detection into their own products — AI Checker provides 90% of the detection capability at a fraction of the friction. Our enterprise tier is available for teams that grow into needing institutional features without losing the focused product they started with.
