Originality.AI

Originality.ai is a content checking suite built around AI text detection. Users paste text, upload a document or point it at a URL, then run scans for AI generated writing, plagiarism, grammar, readability, content quality, guideline compliance and factual accuracy. Results come back as a score for each selected scan, with an adjustable AI allowance threshold and a deeper scan mode for contested cases. It is aimed at publishers, agencies, content teams, schools and individual writers. The detector is trained on adversarial data, so text pushed through paraphrasing and rewriting tools is still meant to register. A Chrome extension runs scans inside Google Docs and records a writing replay showing how a document was typed, which a writer can share to evidence authorship. Integrations cover Google Classroom, Moodle, a Firefox extension, an MCP server and a detection API for high volume use. Team features include role assignment, scan tagging and report sharing, and accounts can opt out of having scans used as training data and delete scan history in one click. Pricing is published in US dollars. Basic is free with AI detection only, three scans per day and a limit of 2,000 words per scan.
