Copyleaks

Best alternative to Ithenticate

Comments: I started using it because my organization stopped paying for another similar service. In the beginning, I didn't understand well how the credits where used. However, it works really well in the end. I used it mainly to check essays of students in English and Spanish.

Pros:

Easy of use, fast and intuitive interface. It is easy to send results to students.

Cons:

The use of credits depending on the number of words is confusing.

One of the best plagiarism checkers out there

Pros:

I've used Copyleaks while writing my master thesis and it has been an excellent experience. Everything from signing up, payments and the actual literature comparison process worked as expected. Having an AI checker in addition to traditional text cross-referencing definitely helped me to feel more confident with the results and in the end my thesis passed all reviews at the university. Copyleaks supports the important and usual file types and does a very good job in parsing PDF files, which, in my opinion, is the most important feature. In my case, I analyzed a PDF generated from LaTeX, and I was happy with the results.

Cons:

At times, viewing the analysis results was a bit laggy on my quite powerful machine, which might be due to having a quite large document or due to the browser itself. Another thing was that sometimes it seemed slightly finicky with whitespace handling. Sometimes it reported very short fragments of general language as plagiarized. I do, however, prefer a higher false positive rate over possibly missed hits.

Copyleaks review

Pros:

It is simple to use. It includes API. Support is always fast and helpful. We get individual pricing plan for our needs, which is not standard for other software.

Cons:

There were some issues with wrong duplicity results and insufficient website indexing. It was addressed and dealt with, but it happened a few times.

Pros:

Copyleaks ensures that our Frontend content is plagiarism free and compatible with sesrch engine SEO algorithm.

Cons:

Copyleaks' paraphrased content detection algorith should be improved with more advance features.

A good service on plagiarism

Pros:

This software can provide plagiarism service, with high quality, for multiple languages other than English.

Cons:

The API response is a bit slow. I understand it costs computer resources for plagiarism operation, but obviously it would be better if we can get several initial result within seconds.
