Originality.ai
Originality.ai detects AI-generated text and checks for plagiarism, with fact checking, readability and grammar tools alongside. It runs on a patented modified BERT model, publishes its own false positive rates, and is built around team workflows for publishers and agencies rather than individual writers.
- Publishes its own false positive rates, which is markedly more honest than the category norm
- Fact checking addresses the real risk of generated content better than detection does
- Deep Scan explains its reasoning rather than only returning a number
- AI Allowance acknowledges that zero-tolerance policies are unenforceable
- Detection is inherently probabilistic and cannot prove how text was produced
- Non-native English writing is disproportionately misclassified across this whole category
- The 2,000-word scan cap means long articles consume several scans
