Hi,
What are some accurate and free plagiarism checkers? The ones that appear on google search either have restrictions or are not accurate enough. As a student, I don't have the means to pay for a premium plagiarism checker so, if there are any free and effective ones which I could use to check my research papers then it would be really helpful.

All universities recognised by the UGC can get access to https://shodhshuddhi.inflibnet.ac.in/

Just talk to someone from your university admin to register there for free.

Otherwise, you may try some of these.
