Firstly, I appreciate for your response and thanks for that. Currently I'm using Grammerly which can serve for checking both Grammer & Plagiarism as well. However, I assume it is not solely a plagiarism screener and it is expensive though. So, this made me raise this particular question as I really concerned about it.
I appreciate your response towards my question. Yeah, I agree with the fact that most of the academicians & the researchers prefer Turnitin, however I have come across few people who argue that it is inaccurate and inefficient as well (sometimes).
Plagiarism x checker.. Is a good program and I compare it with turnitin and both are the same.. There is offer in the program of plagiarism x checker about $40 and for life.. I hope this will help you.. With best wishes.
Ternitin but it is not free more researchers wants to checks their work free of cost. Paid software for good researchers to checks plagiarism for trial is hurdle.
Because this is a sensative issue, using free ones is not a good idea I believe. Both performance and database collection of the free ones are questionable and there is a high risk of remaining undetected.
I checked almost all the plagiarism tools before answer this question. I check a document with Turnitin, then with grammarly (https://preparmy.com/recommends/grammarly ) and then with prowriting Aid.
Turnitin is checked and show similarity reports from Internet sources, Publications, and Their own database as well. Number of text many other factor responsible for their higher similarity report.
Grammarly (https://preparmy.com/recommends/grammarly )is also showing Internet source, Publications as well. But their plagiarism percentage is lower because if we add one or two text between any sentence then grammarly not consider it as plagiarised.
ProwritinAid. It show lowest because it only checked through the Internet Source not all the source like publications and others.
Other tools like Plagscan
These all the tools are using Grammarly Ghost api to check the plagiarsim they are not good to use according to my perspective. They also have some limit on number of words to check.
