What is Originality AI?

Originality.ai is a content-quality and verification platform built for publishers, agencies, writers, educators, and teams that need to evaluate written content before publication. The platform combines AI detection, plagiarism checking, fact-checking, readability analysis, grammar and spelling checks, and other content-quality tools in one workflow.

Its AI detector analyzes text for signals associated with AI-generated, human-written, or mixed content and provides probability-based results with sentence-level highlights. Originality.ai also offers multiple detection models designed for different workflows, including academic content, professional publishing, light AI editing, and multilingual content. Its multilingual detector supports 30 languages.

The plagiarism checker identifies matching content, including exact and more complex forms such as paraphrase and patchwork plagiarism. Its fact checker evaluates claims against current online sources and provides supporting sources and citations.

For organizations, Originality.ai supports team management, shareable reports, website scanning, browser extensions, API access, and Moodle integration. The company launched the platform in November 2022, initially focusing on detecting GPT-3-generated content.
