“I write poems from my life experience to help myself and other heal from generational trauma. Even though I write from my heart, I always do a plagiarism and AI check to ensure my work is original. I pasted 10 poems into Cpyscape and the plagerism checker said "No results found for the text you pasted (384 words, $0.05) on 19 Mar 2026 at 9:48 GMT." And the AI said my words were 99% AI and I spend 2 days searching through dictionary and encyclopedia just to make realistic rhymes that was not a co”

“Unfortunately, they no longer scrape many pages on the internet and are not effective at finding duplicate scraped content. Seems like the product has been abandoned, but they're still happy to take $5 for the service. Don't bother with the service, just ask Grok or Gemini AI to help find scraped content.”

NEGATIVE trustpilot

“terrible, some pages listed with plagiarism after clicking on them will show nothing. Then, some pages after clicking will show the plagiarised part for 0,01 seconds, and then disappear. Sometimes, it even says plagiarism, and when clicking on it, there is no wording with plagiarism, no words tagged... this software should be free, such a BS.. I'm angry every time when I open this”

“Copyscape is the most reliable of all I've found - paid and free. I load $10 into Copyscape and run a LOT of articles through it. It starts at .03/search. Not per word. That's 3 cents per search. It's pretty cool, easy to use, reliable, and I trust the results.”

“A friend (no, really, it wasn't me) has found herself with some free time and decided to try freelance writing. She picked up an assignment from a gig website, did the research (reading), and wrote an article. Before turning it in for payment, however, she was required to buy $5 of credits on Copyscape and submit her work to that site. Copyscape appears to be a plagiarism checking site. I looked at it, and I saw nothing about credits. I did see a free version and a premium version, but it looked”

“I’m a freelance writer of many years and this is just not how the industry works. You should never have to pay anything to get paid. I’ve never heard of having to submit work to a third party site or purchase services to verify your work. You’d likely be working with an editor who would have some kind of a process — not sure if in some sectors that would include checking for plagiarism but I haven’t even heard of that. The plagiarism check would be on the client though, not the writer. This just”
