Genie fully supports Chromebooks. However, they must be configured properly.
Some school provisioned Chromebooks are configured to delete all locally saved data and login information when they shut down. This will force students to login each time they open Genie and will delete all saved Auto-Filed articles.
If you are using a school provisioned Chromebook, make sure that the 'User Data' setting in the Google Admin console that manages your school's Chromebooks is set to allow storing and retaining local data.
Google details this setting under 'Sign-In Settings' here.
You may need to contact your I.T department to examine and update this setting. Feel free to contact us as well with any questions at extempgenie@gmail.com.
