Common questions
Yes, if you need to check long essays and also want a plagiarism report in one go. PlagiarismSoftware handles full documents and gives a sentence-level map. Plagium is better for quick checks of short paragraphs.

Plagium wins for everyday casual use with its free daily searches and URL scanning; PlagiarismSoftware is the better pick for heavy document auditing and combined plagiarism checks.
