Originality.ai
The AI detector plus plagiarism check built for content teams
Overview
Originality.ai combines AI content detection and plagiarism checking in one tool, using a credit system (1 credit = 100 words). It stands out for accuracy on SEO and marketing content, and lets you manage multiple sites or projects from a team dashboard. The Pro plan at ~$15/month provides 2,000 monthly credits, or roughly 200,000 words.
A robust API and URL-based scanning (no copy-paste needed) make it a serious choice for content agencies and e-commerce sellers producing large volumes. Reports include a readability score and 365-day scan history.
Our verdict
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.
