Searched for some tools to help me get better at writing content and I was using free plagiarism tools to check my text is unique ( Even if I know it is, as I write it, but a check is not a bad idea )
I used till now :
http://www.quetext.com/
and
https://www.callseotools.com/plagiarism-checker <- even if its unique it detects 100% plagiarism, don’t know why.
What do you guys use ?
I don’t write a lot, I mean, I don’t publish a lot of articles especially in last couple of months but when I do, I check them with copyscape.
Isnt copyscape premium ?
Yeah, it’s paid, but you can use it for free to check articles that are already published on your site. I don’t know is there any limit though.
yeah and you can publish articles privately on a site you own, meaning the search engines don’t have to know about that, but as long as they are publicly available through a link you can use it in copyscape.
Checked with copyscape now and got no results. That means its good 
what’s that for?
If you are writing articles and use other blogs are copywriting to check if the article you created is unique
