I use Superhuman for emails, which does not work with Grammarly nor LT. Does paying for the Premium subscription unlock the ability to force spell-checking on any input fields where I can type? A keyboard shortcut would be an ideal way to trigger such forced spell-checking process. I am more than happy to pay for this feature 
Premium won’t help with that, I’m sorry. How exactly does LT not work, could you send a screenshot? Do they have their own spell checker?
When composing emails, I see the following:
There is no indicator that LT is work (as there is no icon at the bottom right corner of the text-input field).
A shortcut to force LT to take over a text field would be helpful to have (though, I don’t know what it takes to build this feature). I only know limited HTML, and find the text typed to the “input field” wrapped in an div element named “ComposeForm-contentEditableWrapper”.
Here is the section that rendered to be the text field in the screenshot. (It appears that the raw text with tags are rendered in this post.).

The problem is spellcheck="false", I think. I’ll talk to our developers to see if we can override this.
