Naven
Glossary
School Chromebook
A managed laptop issued by a school, usually locked down against installing software.
Tens of millions are in use, and they are the primary computer for a large number of students. Administrators control the extension list, the app list and often a site allowlist. Anything that requires an install is effectively unavailable.
This is why browser-based tools matter disproportionately in education.
Where Naven stands
Naven runs in the browser with nothing to install, so install restrictions do not apply. There is a help page specifically about using it on one.
