Get suggestions without typing even single word.
Replies applies the same logic to content of incoming messages as it does to inputs in the contact form.
That way snippets with keywords will be automatically suggested if Replies finds them in the incoming message. Plus if you assign to-dos to messages, you’ll see responses (= snippets) you gave before for the same to-do. This comes handy if you get e.g. a lot of requests for the same bug.
