August 2023 Update - AI Writing Check is no longer available

👋 Educators, we have taken down AI Writing Check because the new versions of Generative AI tools are too sophisticated for detection by AI. When we launched this tool in January 2023, the only Generative AI tool available was ChatGPT. There are now a series of different tools available, and each of these tools is being upgraded weekly. As these tools make their AI more complex, the AI text output becomes more varied, and it becomes more difficult for algorithms to detect whether a piece of writing was generated by AI.

As a result, OpenAI has taken down their algorthim. We were hosting the algorthim created by OpenAI, and we are now taking this algorthim down as well.

However, there is an alternative approach for educators to understand their students’ writing: check the version history. We recommend this piece, by Dave Sayers, that describes this approach:

“[The] answer lies in a somewhat obscure feature of Google Drive: the “version history”. Pick any file you’ve worked on in Google Drive, then click on File > Version History > See Version History, and you’ll be presented with a detailed log of all changes made to that file. If it’s been edited by different people, you’ll also see which user made each change. Microsoft Office seems to have a similar feature, too. Click into the details in that log and you’ll see every little sentence you added, every typo you corrected, every awkward passage you rephrased or deleted. It’s really remarkably useful as a writing aid, not to mention a way to recover stuff you actually wish you hadn’t deleted. But it also leaves a very particular – and very human – trail of writing.If a student actually does the writing themselves, they will similarly write things, move things around, add bits, delete bits; all the usual meandering manoeuvres of human writing. And all of that will appear in the version history, indelibly timestamped and tagged per user.

If, on the other hand, it was written for them – either by a machine or indeed by an old-fashioned human ghostwriter – then they would receive a completed text, which they could then only copy and paste all at once into the document. Even if they went to the trouble of manually typing out a provided text, the version history would simply show them typing it out word by word from start to finish. No human writes that way.”

Educators, we created a toolkit to help you talk about AI plagiarism with your students

With the introduction of this new technology, students are curious about how to use it. We believe that if students use AI tools as research tools, and properly cite it as a source, it can help students learn about new ideas. However, when students pass off AI generated writing as their own, they are not engaging in the critical process of building their own writing skills. To help you set the right expectations with your students and navigate these conversations, we created a toolkit.
