Originality AI

Originality AI is a content scanning tool that analyzes submitted text and produces a probability score indicating whether the content was written by a human or generated by an AI model. The detection system is trained against outputs from major large language models including ChatGPT, Claude, Gemini, and others. Each scan also runs a simultaneous plagiarism check against indexed web content, returning both results in a single report. Users can submit text directly, upload files in formats including DOCX and PDF, or enter a URL for full-page or full-site scanning. The credit-based system charges one credit per 100 words scanned, with credits available through one-time purchase or monthly subscription plans. Originality AI is used primarily by content agencies, SEO publishers, and academic organizations that process large volumes of written material. Content managers use the team management features in the Pro plan to assign scanning tasks across team members, track usage, and maintain a shared history of past scans. Publishers running full-site audits use the URL scanning feature to verify large volumes of existing content at once. Beyond core AI and plagiarism detection, the platform includes readability scoring, grammar checking, and a fact-checking aid, which position it as a broader content quality tool rather than a single-purpose detector. Chrome extension support and a WordPress plugin enable scanning from within common editorial environments. View alternatives.
