The desktop section presents replying, draft review, accepting suggested text, completing a thought, requesting edits by voice, asking the inbox assistant questions, and archiving. Its captions read: “Tab to reply,” “Review what’s ready,” “Tab to accept,” “Finish the thought,” “Say what to change,” “Ask your inbox,” and “Tab to archive.”
