Two instructors at Vilnius University in Lithuania brought in some unusual teaching assistants earlier this year: AI chatbot versions of themselves.
The instructors — Paul Jurcys and Goda Strikaitė-Latušinskaja — created AI chatbots trained only on academic publications, PowerPoint slides and other teaching materials that they had created over the years. And they called these chatbots “AI Knowledge Twins,” dubbing one Paul AI and the other Goda AI.
They told their students to take any questions they had during class or while doing their homework to the bots first before approaching the human instructors. The idea wasn’t to discourage asking questions, but rather to nudge students to try out the chatbot doubles.

“We introduced them as our assistants — as our research assistants that help people interact with our knowledge in a new and unique way,” says Jurcys.
Experts in artificial intelligence have for years experimented with the idea of creating chatbots that can fill this support role in classrooms. With the rise of ChatGPT and other generative AI tools, there’s a new push to try robot TAs.
“From a faculty perspective, especially someone who is overwhelmed with teaching and needs a teaching assistant, that’s very attractive to them — then they can focus on research and not focus on teaching,” says Marc Watkins, a lecturer of writing and rhetoric at the University of Mississippi and director of the university’s AI Summer Institute for Teachers of Writing.
But just because Watkins thought some faculty would like it doesn’t mean he thinks it’s a good idea.
“That’s exactly why it’s so dangerous too, because it basically offloads this sort of human relationships that we’re trying to develop with our students and between teachers and students to an algorithm,” he says.
On this week’s EdSurge Podcast, we hear from these professors about how the experiment went — how it changed classroom discussion but sometimes caused distraction. A student in the class, Maria Ignacia, also shares her view on what it was like to have chatbot TAs.
And we listen in as Jurcys asks his chatbot questions — and admits the bot puts things a bit differently than he would.
