How to Use Originality AI to Detect AI-Generated Content


Artificial intelligence (AI) has made incredible advancements in recent years, with models like GPT-3 able to generate human-like text on any topic with just a few prompts. However, this has also led to issues around AI-generated content plagiarizing or copying existing work without attribution.

Originality AI is a platform designed to help identify if text was written by an AI. It uses advanced deep learning models to analyze text and determine if it was AI-generated or original human writing.

In this comprehensive guide, we will cover everything you need to know about using Originality AI to detect AI-written content and ensure integrity in your work.

What is Originality AI?

Originality AI is an online platform and Chrome extension that analyzes text to predict whether it was written by an AI model or a human. It uses supervised learning and a modified BERT (Bidirectional Encoder Representations from Transformers) deep learning model to make highly accurate predictions.

The team at Originality AI has trained its models on millions of AI-generated text records to identify the unique patterns and fingerprints left behind by AI writing. This allows the algorithm to differentiate between human and AI-written work with a high degree of precision.

Originality AI claims over 99% accuracy in detecting AI content across general samples. It also has the lowest false positive rate compared to other AI detection tools.

Why Use Originality AI?

Here are some of the key reasons individuals and organizations should use Originality AI:

  • Identify AI-written plagiarism – Originality AI can detect if an essay, article, or other content was generated by an AI model copying or paraphrasing from existing sources without attribution. This helps identify plagiarism in academic settings.
  • Maintain integrity of human writing – By differentiating human vs. AI writing, Originality AI helps maintain trust and integrity, especially for content marketing, journalism, research papers, and more.
  • Avoid AI-generated spam/abuse – AI models can rapidly generate spam, abusive, fake, or auto-generated content. Originality AI helps identify and filter out AI-generated spam and abuse.
  • Fairness and transparency – Clearly identifying AI-written work fosters transparency and fairness, reducing confusion between human effort vs. automated generation.
  • Classroom anti-cheating – Teachers can use Originality AI to identify if a student’s work was written by an AI, helping enforce academic honesty and integrity.
  • Understand AI’s capabilities and limits – Testing AI-generated content against Originality AI also helps reveal the current strengths and limitations of AI writing models.

The team at Originality AI is dedicated to continually training its models to stay ahead of advances in AI generation capabilities and maintain accuracy over time.

How Originality AI Works

Originality AI uses an ensemble of deep learning models, including a modified BERT architecture, that have been trained on millions of records to identify patterns predictive of AI vs human writing. Here is an overview of how it works:

  • Text input – The user copies and pastes text into the Originality AI web platform or Chrome extension. There are no upload or formatting requirements.
  • Prediction models – The input text is passed through multiple deep learning models that analyze the content, structure, context, coherence, and other linguistic features.
  • Model consensus – An ensemble approach looks at the predictions of each model and determines the overall likelihood the text is AI-generated.
  • Plagiarism detection – Originality AI also compares the input text against its corpus to identify potential plagiarism or copying.
  • Results – Within seconds, the user receives a percentage score from 0-100% indicating the probability the text was AI-written. Results above 95% indicate very high confidence it is AI-generated.

Step-by-Step Guide to Using Originality AI

Using Originality AI to analyze text is simple and only takes a few steps:

Sign Up for Originality AI

First, go to and sign up for a free account.

You can sign up quickly using Google, Twitter, Facebook, or email.

The free plan allows up to 5,000 characters per check.

Paid plans allow unlimited checks and access to the Chrome extension.

Copy and Paste Text

Once signed up, you’ll see the main text input box. Copy and paste your text or document you want to analyze into this box. There is no limit on the amount of text in the free plan.

Click “Check Originality”

Once your text is in the box, simply click the “Check Originality” button to trigger the AI analysis.

View AI Prediction Results

Within a few seconds, your results will appear below the text box. It will show the percentage likelihood the text is AI-generated, from 0% meaning definitively human-written to 100% meaning definitively AI-written.

Any instances of potential plagiarism or copying found will also be highlighted.

Use the Chrome Extension (Paid plans)

With a paid Originality AI plan, you also gain access to the Chrome browser extension. This lets you immediately analyze any webpage or document straight from your browser with one click.

Interpret the Results

Originality AI advises scores above 95% provide very high confidence the text was AI-generated. Scores in the 60-95% range indicate probable AI writing but have some ambiguity. Scores below 60% suggest likely human-written text.

You can use these percentage likelihoods to make informed decisions about the integrity of content.

Originality AI Accuracy

Originality AI claims over 99% precision in detecting AI content across various test samples. Precision measures how accurate positive predictions are (i.e. predicting AI when the content was truly AI).

It has also scored 95% or higher recall, meaning it correctly identifies 95%+ of all AI-generated text content.

The company rigorously trains its ensemble models on large datasets to optimize accuracy. Models only move into production once achieving high enough performance on unseen test data.

For plagiarism detection specifically, Originality AI has over 96% accuracy in identifying if text was copied or paraphrased from existing sources without attribution.

Independent testing has also confirmed strong performance for identifying texts from models like GPT-3 versus human writing. Overall, Originality AI delivers state-of-the-art accuracy for this challenging task of differentiating human vs. AI work.

Limitations of Originality AI

While highly accurate, Originality AI does have some limitations:

  • False positives – Like any AI model, it can occasionally mistake human writing as AI-generated, though its false positive rate is very low.
  • Ambiguity in 60-95% range – Scores in the 60-95% range mean there is some ambiguity whether the text is human or AI-written.
  • Can’t determine source model – Originality AI only predicts human vs. AI, but does not identify which AI model might have generated the text.
  • Evolving AI capabilities – As AI models grow more advanced, Originality AI must continually re-train its models, so performance could degrade over time.
  • Long-form content – Works best for 400+ words. Short text snippets are harder to evaluate.

Despite these limitations, Originality AI remains an extremely useful tool for detecting AI-generated text with a high degree of accuracy.

Use Cases and Applications

There are many potential use cases for Originality AI across education, writing, research, journalism, marketing, and more. Some examples include:

  • Professors using it to check student paper submissions for AI-generated plagiarism
