Decent, google docs feature is good but sharing does not work, it says it generated a link, but no link appears, the link in the top search bar does not work as well, defeats my purpose of downloading

works okay for what it's intended for but is overall a broken extension. it breaks a lot of website code, especially for device theme related stuff which is horrible for accessibility. would recommend setting this to only access site data on click in your browser extension settings

Doesn't work I wanted to see what it thought of my story but won't check it on royal road. Make it compatible with all websites, thank you much.
