ClassChat
(Please

to view our Google Slides presentation.)
ClassChat is an open-invitation online chat service that allows
anyone to seamlessly communicate with anyone in their school.
The COVID-19 pandemic forced schools worldwide to online remote
learning, but this is causing some problems in students. Many
are unable to ask classmates questions, find tutoring support,
or make new friends. It's also not just during the COVID-19 pandemic;
the lack of communication between students has been a chronic issue.
ClassChat allows anyone to seamlessly join any group chat within
their school. It allows better connection among the students,
provides easy access to support, and bridges the gap between students.
