2024 release notes

Interactive detection categories with AI paraphrasing, word count increase, and updated low score treatment

Turnitin license: Turnitin Feedback Studio, Turnitin Originality Check, Turnitin Similarity, SimCheck

Turnitin is excited to release new updates to our AI writing report, including a new visual design, detection categories with AI paraphrasing detection, and an increase to our maximum word count detection.

The AI writing report updates will apply to newly submitted files. To access the latest AI writing report on existing submissions, please resubmit the file to generate the updated report.

In this release, you’ll find the following updates: 

Improved report experience
The previous AI writing report score reflected the amount of likely AI generated text detected, even if it was likely modified by an AI paraphrasing tool or word spinner. In the updated report, the AI writing score is divided into two detection categories with submission highlights enabling a more granular review of AI tools used in the submission. The new submission breakdown bar provides a visual overview of the AI detection instances throughout the submission. 

 

 

Interactive detection categories
In the updated report, the AI writing score is divided into two detection categories, AI-generated only and AI-generated text that was AI-paraphrased. These categories provide more granularity into what AI capabilities were likely used and where, as well as their frequency within the submission. Selecting a category will bring the first highlight detected in the submission into focus.

AI-generated only
This category detects qualifying text that was likely generated from a Large Language Model (LLM). Text of this category is highlighted in a cyan color in the submission breakdown bar and in the submission highlights.  

AI-generated text that was AI-paraphrased
This category detects qualifying text that was likely AI-generated and then likely modified by an AI-paraphrasing tool or AI word spinner, such as Quillbot. Text of this category is highlighted in a purple color in the submission breakdown bar and in the submission highlights.

Interactive submission breakdown bar
Use the new submission breakdown bar for a visual overview of where an AI Large Language Model and AI-paraphrasing tools have been detected within the individual pages of a submission. The interactive bar allows you to select each highlight color to bring the corresponding text and page of the submission into focus. 

Increased maximum word count for detection
The AI writing report now supports submissions with up to 30,000 words of qualifying text.

Scores below 20% are no longer surfaced
False positives (incorrectly flagging human-written text as AI-generated) are a possibility in AI models. To avoid potential incidence of false positives, no score or highlights are attributed for AI detection scores in the 1% to 19% range. When AI is detected below the 20% threshold in the report, it is now indicated with an asterisk (*%) and no percentage is attributed. This change is reflected in new submissions only and will not retroactively apply to existing submissions. 

For more information and comprehensive guidance for these updates, check out our AI writing Report guidance, AI Detection FAQ, and our Academic resources for AI generated text.

Turnitin’s AI writing assessment is designed to help educators identify text that might be prepared by a generative AI tool. Our AI writing assessment may not always be accurate (it may misidentify writing that is likely AI generated as AI generated and AI paraphrased or likely AI generated and AI paraphrased writing as only AI generated) so it should not be used as the sole basis for adverse actions against a student. It takes further scrutiny and human judgment in conjunction with an organization's application of its specific academic policies to determine whether any academic misconduct has occurred.

Missing QuickMarks and long loading time known issue resolved

Turnitin license:

Some of our users reported experiencing delays with loading QuickMark sets or have missing QuickMarks from sets in Feedback Studio. We investigated this issue and can now confirm it has been resolved.

2023 November 1st

New Similarity Report experience now available for instructor

Turnitin license: Turnitin Originality Check, Turnitin Similarity, SimCheck

The new Similarity Report experience provides a more robust look at instances of similarity for faster insights. Instructors will notice some new and familiar tools.

What to expect in the new Similarity Report

Overall Similarity - The overall similarity is the percentage of text in a submission that matches to sources in our database (calculated by dividing the number of matching words by the total number of words in the submission). 

Match Groups - In this new default view, the overall similarity is divided into four categories based on the usage of in-text citations and quotation marks. Any material in the submission matched to a source is highlighted in the corresponding match group color. 

Match groups are only available for English language submissions.

Sources - This view displays a list of sources with the highest percentage of text matched for each submission highlight. Switching to this view will change the match-to-source highlights to a rotating color scheme. Choose the Show overlapping sources option for a list of every source matched to the submission, including sources matched to the same text.

Opt out of the new Similarity Report experience

The new report is still completely optional for instructors. Administrators are able to opt out of the new Similarity Report experience in the account settings. This will disable the new report completely for all instructors.

AI writing detection updates to address our customers’ false positives concerns

Turnitin license: Turnitin Feedback Studio, Turnitin Originality Check, Turnitin Similarity

New messaging for results between 1 and 20 percent

As a result of customer feedback and additional testing, we learned that AI writing detection results between 1 and 20 percent have a higher incidence of false positives. In order to reduce the likelihood of misinterpretation, we have changed the AI indicator and AI writing report to contain an asterisk for percentages less than 20 to call attention to the fact that the score is less reliable.

We have added a new tooltip and in-app notification to help users have a better understanding of the significance of low percentages.

Increased required word count to 300 words

Submissions will now require 300 words of prose text in a long-form writing format order for our model to provide an AI writing detection determination.

Prose text contained in a long-form writing format means individual sentences contained in paragraphs that make up a longer piece of written work, such as an essay, a dissertation, or an article, etc.

AI writing detection model updates

We’ve released an update to our AI writing detection model, which includes:

  • Adjusted how we aggregate sentences at the beginning and ending of the document.

  • Improved handling of formatting and line breaks.

  • Additional resources: N/A 
  • Sharable link for this release note

Administrator settings - AI writing indicator visibility toggle

Turnitin license: Turnitin Feedback Studio, Turnitin Originality Check, Turnitin Similarity

We have released a setting for our administrator users that will allow them to toggle the visibility of Turnitin’s AI writing detection capabilities.

AI writing detection capabilities are enabled for all accounts as default.

If administrators would prefer that instructors in their account do not see our AI writing indicator, they can now hide this feature by going to their account settings, find the section for AI Writing, and deselecting the checkbox.

Once turned off, users will no longer be able to see the AI writing indicator in the Similarity Report. This means they will not be able to open the AI writing report.

This toggle will only impact the visibility of the AI writing detection capabilities, but the AI writing capabilities will still remain a part of our existing Similarity Report workflow.

To turn the visibility of the capabilities back on, administrators can select the same option from their settings page.

AI writing detection

Turnitin license: Turnitin Feedback Studio, Turnitin Originality Check, Turnitin Similarity

Turnitin is excited to release our new AI writing detection capabilities. It is available for all non-student users who can access Similarity Reports, as well as those using them through an integration with a learning management system or Turnitin’s Core API.

AI detection will only work for content submitted in English. It will not process any non-English submissions. As we continue to iterate, we will keep you updated on developments around non-English language support.

We've updated the default Class end date to 12 months (365 days)

Turnitin license: Turnitin Feedback Studio, Turnitin Originality Check

The default end date when creating a new class is now 12 months (365 days).

Previously, unless instructors set a custom class end date, the system default was 6 months (185 days). This was causing classes to expire sooner than desired.

Instructors can still set a custom end date for any class or masterclass they create.
