Frequently asked questions
Why does plagiarism checking need a backend?
Real detection means searching the entire web for matching text, which requires a paid search API — there is no legitimate browser-only way to do it.
Does a match mean plagiarism?
Not necessarily — common phrases and quotes can match innocently. Use the flagged sources to judge in context.
How many sentences are checked?
Up to fifteen substantial sentences per check, to keep searches fast and within provider limits.
