Originality AI is a leading AI content detector and plagiarism checker designed for publishers, content marketers, SEO agencies, and educators. It detects content generated by ChatGPT, GPT-4, Claude, Gemini, and other AI models with 99%+ accuracy on the latest models, while also offering plagiarism scanning, fact-checking, readability scoring, and Chrome extension for in-page detection. Used by 700,000+ users across 130+ countries.
Detect content from ChatGPT, GPT-4, GPT-4o, Claude 3.5, Gemini, Llama, and other models with industry-leading accuracy and frequent model updates.
Built-in plagiarism check scans against billions of web pages, academic papers, and content databases to find copied or paraphrased content.
Verify statements in articles against trusted sources to flag potential misinformation, hallucinations, and outdated claims in AI-generated content.
Multi-user accounts, role-based permissions, scan history sharing, and an API for integrating detection into your CMS or QA workflows.
Scan content directly in Google Docs, WordPress, Webflow, or any website using the Originality AI browser extension without copy-pasting.
Alongside the AI and plagiarism checks, Originality.AI scores each piece for readability and grade level. It is a quick way to catch content that technically passes but reads far above the level your audience actually wants.
Site Scan crawls a URL, a sitemap, or an entire domain and reports AI and plagiarism scores page by page. If you have inherited a site full of outsourced articles, this is the fastest way to find out what you are actually sitting on.
Credits are bought in blocks rather than locked behind a subscription, and every scan produces a shareable, time-stamped report link. Agencies use those reports as proof of human authorship when handing work to clients.
Originality AI combines AI detection accuracy with plagiarism checking and fact verification. Below is a breakdown of its key capabilities.
