Originality.ai
AI detection and plagiarism checking aimed at publishers and agencies.
Positioned for publishers and agencies checking commissioned work, and it combines detection with plagiarism checking, which is the more defensible of the two functions. Treat the detection score as one input among several — the same accuracy limits that apply to every tool in this category apply here.

Copyleaks
Plagiarism and AI detection across many languages, with LMS integrations.
Enterprise and education oriented, with multilingual support and integrations that matter more to institutions than to individuals. The institutional context makes the category's core caveat more serious rather than less: the larger the process built on a detection score, the more people it can wrongly affect.
