"Good checker"

// Private English Tutor at Self-Employed

What do you like about Unicheck?

I like the fact that that Unplag is the single one plagiarism checker that adjusts to my needs, it’s very flexible. Working in LMS, I integrated Unplag to the system and work with the checker straight from it. While integrating, I tuned the checker exactly to my needs. I configured the necessary percentage of originality in each assignment, time when reports arrive, the ability to share the reports and exclude the materials when I allow students to use certain materials.

What do you dislike about Unicheck?

Unplag is cool, but I wish one day the system will also be able to search for the grammar issues. That’d be 2 in 1 so that the whole work with text would basically be finished in the one box.

What have you been using it for and what problems did Unicheck solve?

I use Unplag to check the written assignment of my students to make sure they wrote their assignment themselves. The scanning of papers is really deep, and similarity reports that I get are detailed and clear, with similarities, citations, and references marked. The passages of text get quickly highlighted in the yellow color if they were taken from the Internet or taken from the other student whose work I downloaded to the system for comparison.

When I’m not at school and not teaching, I also use Unplag, I have my individual account. When I write scientific papers I scan them through the checker just like I scan the assignments of my students to keep them free from plagiarism. I’m happy with what Unplag does for me as a teacher and as a writer alike.

"Results are better now"

// Content Marketer and Content Creator at Freelance

What do you like about Unicheck?

Unicheck is very easy to use. It is plagiarism detection software that is used not only by teachers but also by students to check their assignments for plagiarism issues. Unicheck so far is my favorite plagiarism detection software because it is very fast, I can download the documents from my GoogleDrive, Dropbox or OneDrive using the phone. Worth to point out, the checker is also recognizing the references and citations that makes report visually understandable and removes the necessity of manual work with them.

What do you dislike about Unicheck?

I don't like that they don't have a mobile version, it will be so great if they add it. Also having Google Docs plugin would be fantastic.

What have you been using it for and what problems did Unicheck solve?

I’m using it each time I have to scan my writing for plagiarism. Writing the assignment you will be using Internet sources and books, plenty of ideas and material should be cited in such cases. Unicheck finds every instance of plagiarism and delivers the statistics in the report. Viewing the report that highlights the similarities in the yellow color I know for sure where to look for the problem and change my writing accordingly. Unicheck helps me to stay confident that every assignment of mine corresponds to the strict academic standards of the university.

"Finally something worthy for teachers"

What do you like about Unicheck?

Recently a “flipped learning” practice was adopted by the teachers and parents in our classroom. Sure thing, it meant completely different work approach. For now, a great deal of the daily workflow is happening online. New approach means new benefits and new problems. We wrote the essays before straight in the classrooms so I could supervise my students and prevent them from cheating. The benefit of independent writing appeared to have a dark side too, the cheating has gone viral. Working with Canvas, I found a solution that promised to end the problem. It worked.

What do you dislike about Unicheck?

That’d be great if you guys also had this option for the grammar check with automatic word suggestion.

What have you been using it for and what problems did Unicheck solve?

I check all the submissions that students pass and I wouldn’t trade it for anything else because it is: integrated straight to the Canvas, lets me coment straight on the plagiarism reports, makes a simultaneous scanning through the web and compares documents between each other, shows me where’s plagiarism and where are citations and references with colors, and sure discourages the students from plagiarizing.

"If it works for teachers it works for me"

// Self Employed at -none-

What do you like about Unicheck?

For starters, let’s mention I’ve been looking for the plagiarism checker for ages as this year I’ve been caught twice with the issues. It is not fair that teachers have all the software they need for plagiarism scanning while students have to get by some questionable online tools.
I knew that teachers in our college use Uniccheck for scanning the papers. I also recently overheard that Unplag has recently opened the option for student prechecks so I came for the test-drive. Here what I liked the best:

Simple color scheme for report interpreting
High capacity to catch similarities
Multi language checks

What do you dislike about Unicheck?

It would be super cool if the checker also gave some suggestions about my grammar because now I have to run my paper through the Unicheck first and then paste the text to the grammar checker to see if my grammar is ok.

What have you been using it for and what problems did Unicheck solve?

I check all of my papers in Unplag and fix them before it’s too late (before submitting). So, I’m definitely intended to check my future thesis here too as I had no problems with plagiarism since I first started using this checker.

"Thanks, Unplag"

// Self Employed at Self-Employed

Playing with words is my passion. I write every day. And when my thoughts start haunting me, I realize that I should make time and review my works to avoid duplicating my own stories unintentionally. Unplag.com became a real asset for me as it can check documents vs documents. What I did first was uploading all my already written works to the dashboard. With Unplag it is damn easy, as you can drag and drop a folder with files straight into the dashboard. Then I also uploaded one of my latest writings and launched a Doc vs Library check (as it is called). Unplag shows a progress circle, so I knew when the check would be completed. It took about 10 seconds, since I chose about seven files for comparison. The report I got after scanning showed percentage of originality, similarity, and the links to the documents that had similar and exact passages. Clicking the link showed two matching texts side-by-side. It turned out to be very very helpful for me. One more extra thing Unplag can do is to compare texts with web sources. I also made use of this search once and it pointed out two sentences I didn’t cite. Ooops! Good job Unplag!
