writerzen

I compared Quetext, Grammarly, and WriterZen for a plagiarism test and Quetext was the most accurate, then WriterZen came second with decent results. Grammarly was the worst. Is there any LTD for plagiarism checking that delivers better results than WriterZen?

Which tool is good to give NLP google entities, relevant & LSI keywords? Which tool can provide relevancy and much efficient on page power to your article optimization? I have both tools but not sure which one to use on regular basis? Please advise :)
