From Packback's support site:
Packback Questions is an online discussion platform geared towards awakening and fueling relentless curiosity in every student! Packback is an AI-supported online discussion platform designed to improve student curiosity, communication skills, and critical thinking. We have created an academic space where students are free to explore the content you learn in class in a way that spans outside the boundaries of textbooks, lecture halls, and online sources. Instead of just focusing on memorizing facts, Packback places students in the driver's seat, prompting them to ask questions, engage with their classmates, and take their fearless curiosity to new heights.
