Hello! At some point my google notifications got turned off - sorry for the delay. Students would need an account to highlight a text but not to view the visualize pages (we were worried about bots when we made the thing). But those accounts don't need to use real emails - they have to just look like emails. I.e. -
should work, because we don't actually engage with the emails in any meaningful way (asking people to confirm them or anything). So you could create a list of student accounts and passwords that are fake for the purposes of the tool and your class if you're worried about student privacy.
Wondering the same thing.......
