As answered by people managing Originality.AI and StructOCR.
Originality.AI's answer
Originality.AI is the most accurate AI content detector. It is effective on AI-written text created by popular large language models such as ChatGPT, GPT-4 and Bard.
One of the reasons that it outperforms other content detector software tools is that the AI algorithms at Originality.AI use natural language processing techniques which require a lot more compute power. This is also the reason we do not offer a free or ad supported option.

The Originality.AI Story
Jon Gillham founded Originality.AI after selling a content marketing agency he had previously founded.
Originality.AI launched in November 2022 to be able to detect GPT-3 generated content (before ChatGPT had launched).
Having been one of the earliest adopters of generative AI content for SEO purposes at scale through his agency he understood the wave that was coming which Chat GPT and GPT-4 have fully unleashed.
Additionally he believed that there was a need for a modern plagiarism checking solution that didn’t suck! One that provided scan history, detection scores, shareable results, team access etc etc… what you would expect from a modern Plagiarism Checking solution.
The team now includes experienced Machine Learning Engineers and Researchers, Developers and Marketers all on a mission to try and provide transparency on the true originality of any writing.
