Discover what Originality.ai is — an AI content detector, plagiarism checker, and fact-checking tool built to reduce false positives. Learn about its

Originality.ai is a suite of tools designed specifically to detect AI-generated text, with a focus on content created by GPT-3 and GPT-4. It combines AI content detection, plagiarism checking, fact-checking, and readability tools in one platform. The team behind it consists of experienced machine learning engineers, researchers, developers, and marketers focused on giving clear insights into how original a piece of writing is.
A key differentiator is its emphasis on reducing false positives — cases where human-written content is incorrectly flagged as AI-generated. Originality.ai reports a lower false positive rate than many competing tools. It can also detect paraphrased content, and it offers a free Chrome Extension that shows the creation process of a Google Document, letting writers demonstrate their work’s authenticity.
Originality.ai was founded by Jon Gillham after he sold a content marketing agency he had built. It launched in November 2022, initially to detect GPT-3-generated content, with the goal of building a modern plagiarism checker that included scan history and team access features.
