Developers get API access for building AI detection into their own apps. The Chrome extension can replay document creation history — showing exactly how someone wrote their content. This patented technology helps prove original authorship when disputes arise.

Content managers at publishing companies face constant pressure to verify authenticity. Originality.AI scans entire websites in bulk. It identifies text from GPT-5. ChatGPT. Claude 4. Other major AI writing tools too. Independent studies show 97.09% accuracy. It consistently beats competitors like GPTZero and TurnItIn.

You can upload PDFs or scan URLs directly. Deep Scan explains why content gets flagged as AI-generated and suggests specific edits. Grammar checking rounds out the toolkit. Fact verification too. The plagiarism scanner only checks against internet sources rather than academic databases though.

Readability scoring helps optimize content for target audiences while Content Optimizer uses AI to improve Google rankings. WordPress and Moodle plugins bring detection capabilities directly into existing workflows.

The free plan includes basic AI detection and the Chrome extension. Writers get straightforward tools for maintaining content integrity. Students and educators do too. Picture a magazine editor who needs to verify that freelance submissions aren't AI-generated. They can scan articles, check the creation replay, and get detailed explanations for any flagged sections. The accuracy rates speak for themselves: 100% detection on GPT-4 papers and 87.9% mean performance across various AI versus human text comparisons.

Frequently asked

7 questions
How accurate is Originality.AI compared to other detection tools?
Independent studies put Originality.AI at 97.09% accuracy overall. It nails 100% detection on GPT-4 papers and keeps 87.9% mean performance across AI vs. human text comparisons. Beats competitors like GPTZero and TurnItIn consistently in head-to-head tests.
Can the Chrome extension really show how someone wrote their document?
Yep -- it replays the entire document creation history. You'll see exactly how content got typed, pasted, or edited over time. This patented tech creates a timeline that can legally prove original authorship during disputes (or plagiarism accusations).
What's the difference between regular scanning and Deep Scan in Originality.AI?
Deep Scan goes way beyond flagging AI content. It explains exactly why text triggered detection -- shows which sentences or phrases look AI-generated and suggests specific edits to improve authenticity. Regular scanning? Just gives you the percentage breakdown without detailed analysis.
Does Originality.AI work with GPT-5 and Claude 4?
Yes, it catches content from GPT-5, ChatGPT, Claude 4, and other major AI writing tools. The system updates regularly to catch new AI models as they're released. This keeps detection accurate even as AI writing tech advances.
Can I scan entire websites at once with Originality.AI?
Absolutely. You can scan entire websites in bulk rather than checking pages one by one. This feature's perfect for content managers at publishing companies who need to verify authenticity across hundreds (or thousands) of pages quickly.
What doesn't the plagiarism checker cover?
The plagiarism scanner only checks against internet sources -- not academic databases. Need to compare against research papers or academic journals? You'll need a different tool. It's built more for web content and general publishing than academic integrity checking.
Do I need to pay to try Originality.AI's main features?
The free plan includes basic AI detection and the Chrome extension replay feature. You can test core functionality without paying upfront. Paid plans add bulk scanning, Deep Scan analysis, and additional tools like fact verification and content optimization.
