Originality.ai is an AI content detection and plagiarism checking platform designed for content publishers, SEO professionals, content agencies, and website owners who need to verify the authenticity and originality of written content. The platform uses proprietary AI detection models to identify text generated by AI language models including GPT-4, GPT-3.5, Claude, Gemini, Llama, and other large language models, providing a percentage-based score indicating the likelihood that content was AI-generated versus human-written. Originality.ai's detection engine is continuously updated to keep pace with new AI writing models and techniques, including detection of paraphrased and edited AI content. The plagiarism checker scans content against web sources to identify duplicated or closely matching text, providing source URLs and match percentages. The platform offers a readability analysis feature that scores content for reading level and accessibility. Originality.ai provides both a web-based interface for individual content checks and an API for integrating detection capabilities into existing content management workflows. Team features include shared scan history, team member management, and usage tracking across an organization. The platform offers a Chrome extension for scanning content directly on web pages and within content management systems. A site scanner feature allows users to scan entire websites for AI-generated content by crawling published pages. Originality.ai also provides a fact-checking feature that uses AI to verify claims made within content against reliable sources. The platform is widely used by content agencies, freelance marketplaces, publishers, and academic institutions. Pricing operates on a pay-as-you-go credit system starting at $14.95 per month for a base plan, with each scan consuming credits based on word count.
