From the description of the add-on, it is not clear why it requires the permissions "Get data from the clipboard", "Input data to the clipboard" and "Access browser activity during navigation"?

I was looking for something to replace grammarly, but this one is nowhere near that smooth experience. Which is fine. Then you realize the paid version is $25 a month, which is insane. It's not worth that much. Maybe $1 or $2 a month, not even $3.
