Student voices

Students love Class Companion. It’s motivating and fun.

“I like that I can know what I said wrong right away. When it takes a while to get back grades, I forget why I said what I did. With the AI, I'm still in the frame of mind so I can understand what I did right or wrong.”
Tennessee English student
“It challenges me to really think through my questions and answer honestly without writing down bull. Also it forces me to read through primary sources which makes me feel confident in the work that I do in class.”
California US History student
“I really liked the details and explanations for contextualization. I found it really useful and feel as if it will help me when I write my next LEQ. It provided valid criticism…and didn't dock points blindly.”
New York AP World History student
