Hold Right Ctrl in a Gmail reply and say it the way you would say it. It lands as a proper email: full sentences, paragraphs, nothing invented.
yeah thanks for the photos, they look the kitchen looks great, um can you send the final invoice when you're done and I'll pay it the same day
Perfect Dictation sees that you are in Gmail and writes the way emails are written. Change it any time, or make a style of your own.
Want it different? Make your own style in plain words, like "keep it under three short sentences".
All of them work in every app, and none of them needs a plugin.
Select text you already typed, hold both keys and say how to change it: "make this friendlier", "shorter".
Not what you meant? Ctrl+Z takes it back like any typing, and History keeps a copy you can paste again.
Fix a name once in History and it is spelled that way from then on: people, products, your company.
Every app with a text box works. These get a style picked for them automatically.
No. Perfect Dictation types into whatever window has your cursor, so there is nothing to install in Gmail and nothing to connect.
No. It only sees the app's name, to pick the style. It never reads what is on screen, and your words are not kept on our servers.
Yes. Pick any style for Gmail in Settings, or write your own in plain words and it is used there from then on.
