Loving it so far! I can check my paper before I submit it. Heads up: not all colleges use this site to check work. It is not as accurate as Turnitin.

Creative writers should NOT use Copyleaks. Although it appears to be a good tool for detecting plagiarism in academic research papers, the company's pricing model lacks transparency, and the AI detection scans are worthless for prose, screenplays, poetry, and other varieties of fictional creative writing. Furthermore, getting actual support is nearly impossible; my experience with their "customer support" strongly suggests that Copyleaks has replaced human support with an AI designed to obstruct customers rather than support them. Copyleaks deceptively seems affordable, but it is a costly, inaccurate tool that offers zero recourse for paying customers.

Pagué por la suscripción para estudiantes confiando en su detector de IA. Pasé mi trabajo de ingeniería varias veces por su plataforma hasta que me aseguró que tenía 0% IA. Sin embargo, al entregarlo en mi universidad, el sistema Turnitin detectó un 78% de IA, perjudicándome gravemente con mi docente. Su herramienta no es confiable, da falsos positivos y falsas sensaciones de seguridad. Ya abrí el caso de soporte técnico número 00063440 exigiendo una solución y mi reembolso.

Although the agent is helpful in assisting me with my inquiries, the time I have to wait for the IT to recheck and resolve my issues is taking longer than expected. Hope this can be fix
