Rewrite Dictated Text as Formal or Informal, in One Click

The way you'd naturally say something out loud and the way it should read in, say, an email to a client are often two different registers. Dictating usually means picking one and living with it, or manually rewriting afterward.

Why tone and grammar are two different jobs

Fixing grammar means correcting mistakes while leaving everything else, including tone, exactly as it was. Shifting tone is a deliberate rewrite: the words change, sometimes a lot, while the meaning and the person speaking stay the same. Treating them as the same operation tends to produce text that's technically different but not actually more formal, or that drifts into a different voice altogether.

What a real tone shift has to preserve

• — Who's speaking and who's being addressed. A formal rewrite should still sound like the same person talking, just more formally, not a narrator describing them.
• — The actual meaning. Nothing gets added or left out, only the register changes.
• — Correct grammar for the new register, including the specific grammatical shifts a formal or informal register requires, not just vocabulary swaps.

Where this is actually useful

Dictate a quick, casual update the way you'd say it out loud, then decide afterward it needs to go out as a formal message, without redoing the dictation itself. Say something bluntly, then soften it, or the reverse, cut the formality out of something that was accidentally stiff.

The bottom line

Talk however it comes out naturally. The tone is a decision you can make afterward, not a constraint on how you have to speak in the moment.
