YoChatGPT! brings the power of AI to group learning

While generative AI is widely recognised for its ability to write essays, create visuals, and generate code, its use has so far been largely limited to individual users. In contrast, interactive online chatrooms enable virtually unlimited numbers of participants to engage in real-time, multi-party communication. Recognising the potential synergy of these two technologies, Dr Fridolin Ting Sze-thou from the Department of Mathematics and Information Technology (MIT) and his research team have developed YoChatGPT!, a pioneering platform that combines the benefits of generative AI and collaborative chat spaces.

“By integrating various large language models (LLMs) into traditional chatrooms, YoChatGPT! promotes collaborative learning and enriches the educational experience by allowing users to interact with AI collectively,” Dr Ting explained. “It enables the shared use of generative AI, fostering creativity and teamwork among participants.”

“The platform was specifically designed to overcome the constraints of single-user AI tools by enabling collaborative, transparent, and curriculum-aligned learning,” Dr Ting elaborated. Key features of YoChatGPT! include multi-user synchronous chatrooms, integration of multiple LLMs, and STEM-specific tools such as handwriting recognition for mathematics and text-to-scientific-diagram generation. It also employs Retrieval-Augmented Generation (RAG) to deliver personalised, context-aware responses with respect to the subject curriculum of the learner.

“Imagine a group of students in Hong Kong and Ottawa in Canada collaborating on a joint project using YoChatGPT!,” Dr Ting said. “If they wish to compare the two locations, they can select any of the 20 embedded LLMs and request comparisons of demographic trends, cultural similarities, or other influencing factors. Each student can contribute by posing their own questions, encouraging a more interactive and dynamic exchange of ideas.”

YoChatGPT! also enhances STEM learning significantly. For instance, if a user types the prompt “draw a 3D pyramid with steps”, the platform generates a triadic pyramid similar to those found in Maya culture. Conversely, it can recognise and convert handwritten mathematical content, such as algebraic fractions or matrix calculations, into clean and precise mathematical expressions, making it an invaluable tool for teaching and learning mathematics.

Its Retrieval-Augmented Generation (RAG) function further supports personalised learning. “If I use YoChatGPT! during a lesson and ask it to summarise a particular viewpoint discussed in class, the system will identify relevant content in the chat room, and from PDF and PowerPoint files shared on the platform, extract key insights, and generate a coherent and informative summary,” Dr Ting explained enthusiastically.

To promote the platform, Dr Ting’s team has organised more than 30 workshops, seminars, and conference presentations locally and internationally, engaging over 20,000 teachers, students, and education professionals. “An increasing number of people are using the platform to support teaching and learning,” Dr Ting noted. “At present, YoChatGPT! has around 30,000 active users from over 120 countries, with an average of 2,000 new active users joining each month.”

Dr Ting embraces John Dewey’s educational philosophy: if we teach today’s students as we taught yesterday’s, we rob them of tomorrow. “When I guide students in using YoChatGPT! on a project, each student can prompt the AI for relevant data, request analyses, or ask for suggestions on improving their work,” he explained. “This AI-assisted collaboration encourages exploration, problem-solving, and knowledge building, empowering students to learn on equal terms. That’s what makes YoChatGPT! so special.”

The innovation has earned Dr Ting and his team multiple international accolades in recognition of its original and transformative approach to education. These include the Silver Medal at the 12th QS Reimagine Education Awards, the Silver Medal and Special Award at the 10th International Invention Innovation Competition in Canada (iCAN 2025), the Silver Medal at the Silicon Valley International Invention Festival (SVIIF), and the Silver Medal at Inventions Geneva 2025.

The research team is now exploring new avenues for YoChatGPT!’s growth, including partnerships with government agencies, international enterprises, and start-ups to position it as a leading platform for virtual competitions and cross-sector forums. They are also considering introducing a subscription service for institutions and businesses. In addition, the team plans to incorporate field-specific LLMs to ensure users receive the most relevant and effective AI support for their projects.
