plagiarism detector

I have DL DupeFree Pro but it seems like it is geared more towards "spinning articles."

With DupeFree Pro you have to highlight each sentence for it to check online or else it just randomly checks 5 sentences.

Is there any program that you can check for plagiarism with uniquely written content without highlighting every single sentence?

(I searched but couldn't really find anything "good")
Thanks!

CopyScape paid lets you check content that's not online yet. You just copy/paste it into the input box and hit the button. It's only $5/100 checks.

If the content's already online, you can use their free version, but with articles for AC that is unlikely to be the case.

Does that just send you to google with the all text search operator?

I have been using a Copyscape premium account for years. It helps me ensure that what I deliver to my clients isn't plagiarized.
