The short answer
No. It tidies punctuation, fillers and the parts you corrected yourself, and never adds names, facts, numbers or sign-offs you did not say.
What the clean-up does
Raw speech, written down word for word, is hard to read. People say "um", start a sentence twice, and correct themselves on the way. The clean-up turns that into the text you would have typed:
| You say | It writes |
|---|---|
| so um can we move the the call to uh Thursday | Can we move the call to Thursday? |
| send it Tuesday no Wednesday | Send it Wednesday. |
| the total is you know about four thousand | The total is about 4,000. |
- Punctuation and capitals are added.
- Fillers such as "um", "uh", "like" and "you know" are removed when they are filler, not meaning.
- Repeated words and false starts are taken out.
- Self-corrections keep only the version you settled on.
- Numbers, dates and times are written the way you would type them.
What it never does
- It never adds facts: no names, dates, prices or details that you did not say.
- It never adds sign-offs or greetings you did not say.
- It never answers your question or replies to the text: if you dictate a question to an AI tool, it writes your question, it does not answer it.
- It never changes your opinion or tone into something you did not mean.
How much it changes depends on the style
The Clean style changes as little as possible: punctuation, fillers and obvious repeats. Styles such as Email or AI prompt also shape the text for where it is going, for example tidying a ramble into clear sentences. Even then, the rules above still hold: the meaning and the facts are yours.
If you want text closer to word for word in one app, set that app to Clean. See What are styles?
You can always check
Every dictation in History shows exactly what you said next to what was written, with the removed words struck through. See Can I see what was changed?
Why this matters for professional writing
In a medical letter, a legal note or a client email, one invented detail would be worse than any typo. That is why the clean-up is told to work only with your words: it may reorder a clumsy sentence, but it may not add a dosage, a date, a sum of money or a name. If something you said was unclear, it keeps your wording rather than guessing.
Always read what you are about to send, as you would with anything you typed. Dictation saves you the typing, not the final check.
