Editorial note

Originality.AI is an AI content detector and plagiarism checker. You paste text, upload a file or scan a URL, and it reports how likely the text is AI-generated, flags copied passages, and scores readability and grammar. A Chrome extension works in Google Docs and can replay how a document was written.

Who it’s for

• Publishers and site owners reviewing freelance articles
• Content agencies checking work before delivery
• Editors and teachers checking authorship
• Not ideal for: anyone wanting a final verdict on authorship from a single score.

Key use cases

• Write & chat
• Research & answers

What you can do with it

Originality.AI helps editors judge where content came from before they publish. Each scan runs AI detection and plagiarism checks and can add content quality, readability, grammar, guideline and fact-checking aids. Teams scan in bulk, share reports and tag scans, and Enterprise adds API access. Originality says it tests against tools that rewrite text, such as paraphrasers, to keep detection working.
