Scribbr
A completely free, no-signup detector aimed at students.
Scribbr's detector is positioned squarely at students who need a trustworthy check before submission and do not want to pay. It is free, requires no account, and explains its flags in plain language so users understand why a passage was highlighted. Independent accuracy sits around 90%, which is strong for a free tool. Because it is tied to Scribbr's broader academic editing brand, the guidance tends to emphasize responsible use rather than evasion. For a student doing a final self-check, it is one of the most accessible options available.
