Our verdict: Copyleaks
Copyleaks is a solid choice for an SME or training organization needing a versatile, multilingual, well-integrated tool. The free plan suffices for very occasional use. On the flip side, it's pricier than ZeroGPT or GPTZero for heavy use, and AI detection accuracy remains imperfect like all competitors.
Our verdict: Originality.ai
Originality.ai offers the best value for an agency or marketing team publishing regularly. No free plan, but 50 credits on signup allow serious testing. Caveat: like all detectors, it can be fooled by reworked AI content: don't make it your only quality filter.
