The useful answer is not who wins generally. It is who wins for a specific job.
Turnitin: Turnitin remains the reference point most universities and students recognize.
Copyleaks: Users can reach it directly without the same school-controlled workflow.
A comparison page stays useful when it still gives each option enough texture to trust the verdict.
Turnitin matters because students search for it constantly, but access model and workflow are very different from public tools.
Copyleaks is a useful comparison target because it sits between institution-only products and student-facing self-serve tools.
This is where the comparison page stops sounding like a mirror copy of the product pages.
Answer the obvious objections directly.
Copyleaks is the clearer public option. Turnitin depends heavily on school access.
Because users search with urgency and already understand the problem they need to solve.
These link clusters are what let the site expand without becoming a maze.
