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.

Studies on "Do AI Detectors work?"

Our unfair advantage

Why are we most accurate?

AI Detectors without an in-depth analysis verified by third party studies should be used with caution.

Sign up now ›

Proven Third-Party Accuracy

You don’t just need to take our word for it. Independent third-party studies have also found the Originality.ai AI detector to be exceptionally accurate.

Accurate on Latest Models

We are constantly testing our AI detection models against the latest flagship models from OpenAI, Anthropic, Meta and other leading LLM providers.

Built and Trained on “Adversarial” Datasets

We have a full time “Red Team” that is actively testing strategies to make undetectable AI content. Once they find a strategy (such as Paraphrase Plagiarism) that can create high quality undetectable AI generated text and bypass our AI content detector we improve our AI technology and make it detectable.
