Our AI Checker is Built for Copy Editors & Publishers - (Not Students)

By narrowing our focus on serving Copy Editors and Publishers, we have built the most accurate AI checker with key features so you can publish with integrity. We are not against AI generated content, but believe that YOU should be the one making the decision on if and when you publish it.

Most Accurate AI Detector

Our AI detector has repeatedly been shown to be the most accurate at detecting AI generated content by both our internal testing and 3rd party peer reviewed studies. Across all Large Language Models (LLMs) including Chat GPT, GPT-4, GPT-3.5, Bard, Llama 2, Claude 2 and even Baidu’s Ernie we are able to detect AI generated text.

Any AI detectors accuracy claim that is not supported with an in-depth analysis should be viewed skeptically.

Do AI Detectors Work - Studies:

  • Published 3rd Party Accuracy Study
    Our Detector was the most accurate at 97%
  • Our AI Detection Accuracy Study
    Our detector was the most accurate across multiple publicly available datasets tested.
    We built and open-sourced a testing tool to help others replicate on their own data.

Why Are We The Most Accurate?

  • Large AI Models - Because we are not built for Students and therefore we only offer the limited free AI Checker above we can focus our resources on using a larger AI detection model.
  • Focus on Published Text, Not Academia/Research/Historical Text - Instead of training our detector on all types of written text our model specializes on content meant to be published on the internet or in print and created for the average reader (web content, blog posts, books, news etc).
  • Build and Train on “Adversarial” Datasets - We have a full time “Red Team” that is actively testing strategies to make undetectable AI content. Once they find a strategy (such as paraphrase plagiarism) that can create high quality undetectable AI generated text and bypass our AI content detector we improve our AI technology and make it detectable.

Originality.ai did a fantastic job on all three prompts, precisely detecting them as AI-written. Additionally, after I checked with actual human-written textual content, it did determine it as 100% human-generated, which is important.

Frequently Asked Questions

How Do AI Detectors Work?

Our internally built artificial intelligence uses supervised learning with multiple models including a modified BERT & Roberta model to predict if it is Human or AI written content. Our AI has been provided with millions of records both AI and Human text then trained to tell the difference between the two.

Can Google Detect and Penalize AI Content?

Google along with other search engines has made it clear that “Using automation - including AI - to generate content with the primary purpose of manipulating ranking in search results is a violation of our Spam Policies”.

Additionally we found that Google Adsense can identify AI generated text and rejected a website because of AI generated text (study).

Does Originality.ai Have a Free Trial?

Yes, we provide two opportunities to try our AI content detectors capabilities for free. You can can use our Free AI Detector at the top of this page or you can also signup and receive 50 free credits within our app.

Do AI Detectors Work and Can ChatGPT Be Detected? 

Yes, Chat GPT generated content along with most LLM’s (Bard, Claude 2, Llama 2 etc) can be detected at a high rate of accuracy. They are not perfect and do have some false-positives. An AI detector does “work” depending on the level of accuracy, precision and recall you require.
