OriginalityAI

Originality.ai is a content integrity and QA/QC toolkit built for writers, editors, marketers, publishers, teachers, and students. It combines an AI detector with plagiarism checking and additional quality checks, so you can review text for integrity signals before submission or publishing.

Start by running AI Detection to estimate whether your content is likely AI-generated, likely human-written, or mixed. Use the plagiarism checker to identify close matches, then refine your draft with grammar and readability checks. For factual writing, the Fact & AI Hallucination checker helps review claims and surface potential issues so you can verify what needs attention.

When results look questionable, Deep Scan helps explain why the text may be flagged as AI and provides guidance to edit it more naturally and ethically. You can also see sentence-level highlights to understand which parts are most likely driving the AI signal.

Originality.ai supports flexible workflows, including options for scanning different scan types, bulk scanning, and site scanning to scale reviews. If you need to share outcomes, you can generate shareable reports and export results to Google Docs or Microsoft Word, plus access scan history and remove scan history with one click. Free AI scans are available with a 100-credits limit per account, and account holders can opt out of AI training data use.
