Does Originality.ai Provide Paraphrase Detection?

Yes, Originality.ai offers an industry-leading AI detector for identifying AI-generated and AI paraphrased content. Our detector has been trained to detect if content has been paraphrased with a tool like Quillbot or humanized with a popular AI humanizer (see our accuracy study for insights into AI detection on popular AI humanizers). If a piece of text, regardless of whether it started as AI or Human, is run through a paraphrasing tool like Quillbot, Originality.ai will identify the content as AI-generated 95% of the time.

What Are AI Detection False Positives?

False positives do occur and can be painful. At Originality.ai, based on our accuracy study, our Lite model has a 0.5% false positive rate, our Turbo model has a 1.5% false positive rate, and our Academic model has a The AI researchers and machine learning engineers at Originality are working constantly to both improve detection accuracy and reduce false positives. We are heavily focused on equipping writers with tools to help them prove their content’s Originality, which is why we developed a free Chrome Extension that allows anyone to visualize the creation process of a Google Doc.

Estudos sobre "Os detectores de IA funcionam?"

Nossa vantagem injusta

Por que somos os mais precisos?

Detectores de IA sem uma análise aprofundada verificada por estudos de terceiros devem ser usados com cautela.

Inscreva-se agora ›

Precisão comprovada por terceiros

Você não precisa apenas acreditar na nossa palavra. Estudos independentes de terceiros também constataram que o detector de IA da Originality.ai é excepcionalmente preciso.

Preciso nos modelos mais recentes

Estamos constantemente testando nossos modelos de detecção de IA em relação aos mais recentes modelos emblemáticos da OpenAI, Anthropic, Meta e outros principais provedores de LLM.

Criado e treinado com conjuntos de dados “adversariais”

Temos um “Red Team” em tempo integral que está testando ativamente estratégias para criar conteúdo de IA indetectável. Assim que encontram uma estratégia (como plágio por paráfrase) que consegue criar texto gerado por IA indetectável de alta qualidade e contornar nosso detector de conteúdo de IA, melhoramos nossa tecnologia de IA e o tornamos detectável.
