I have tried a number of plagiarism detection tools. The good ones tend to be quite expensive if you don't use them a lot, so I was attracted to the 'pay for what you use' credits model of Originality.
I looked for a trial, but there isn't one. You have to sign up and purchase 1,000 credits in order to try the platform. Going by all the hugely positive comments about this product on PH, I thought I would give it a go anyway.
Unfortunately, I was immediately disappointed. I pasted in a blog post which had been written for me by a copywriter I was trialling. After a bit of thinking, Originality told me my text was 100% original.
I ran the same text through a plagiarism tool which I trust (but which is expensive) and it showed the same blog post was 58%(!) plagiarised, which I was able to verify - it's riddled with copied text - some text is slightly reworded, but some is directly copied-and-pasted from existing articles.
So.... I don't feel this tool will meet my needs in its current state. And I have loads of credits left to use. I have not tested out the AI detection mechanism, which might still be a use for those credits, if it works.
