Incorporating research and best practices in large language models and retrieval augmented generation, the CurioAI Learning Companion is a software framework with a no-code interface that helps educators easily build high-quality, custom AI teaching assistants for their classes. It works not only for lecture-based classes but also supports open-ended and project-based learning. In collaboration with the FabLearn Fellowship’s existing global network in 24 different countries, we are also establishing partnerships among researchers, educators, and engineers to help push forward the design and implementation of custom AI applications built with the CurioAI toolkit in various learning contexts.
