Check-Plagiarism’s Detection quality — 32.5/50 ⭐️⭐️⭐️’s performance in plagiarism detection is moderate at best, scoring 32.5 out of 50. It shows some capability in identifying human-written text as unique, with an 87% free score, but struggles significantly with content copied from the internet and AI-paraphrased materials, detecting only 66% and 50% of plagiarized content, respectively. The service completely fails to identify text modifications as plagiarized. This indicates that while might be useful for basic checks, it is not reliable for thorough academic or professional plagiarism detection needs.

Check-Plagiarism’s Value for Money — 14/25 ⭐️⭐️⭐️

Offering a range of affordable subscription plans, provides a basic level of service that might appeal to individuals or organizations with limited plagiarism detection needs. The pricing structure is competitive, but the value proposition is diminished by the tool’s limited detection capabilities and source coverage. Without discounts for longer commitments, the service’s appeal is further constrained, particularly for those seeking comprehensive plagiarism detection solutions.

The user experience of is straightforward, scoring 13 out of 25. The website is easy to navigate, and users can start checking texts without the need for registration, making it accessible for quick checks. However, the overall experience is hampered by the lack of a desktop app, browser extensions, and comprehensive support options.
