How to Use Auto Cleanup (Beta)

Last updated: April 29, 2026

Available on: Coming soon to Mac and Windows

Auto Cleanup polishes your dictation before it's inserted — removing filler words, fixing grammar, or rewriting for clarity. Pick one of four levels to control how much Flow edits your speech.

What it is

Auto Cleanup runs automatically on every dictation before text is inserted. You pick the level once, and Flow handles the rest — there's nothing extra to press or trigger.

Unlike Transforms, which you apply manually to highlighted text after the fact, Auto Cleanup works in the background on every dictation.

When to use it

Use this feature when you want to:

Remove filler words like "um" and "uh" automatically
Get cleaner, more professional text without editing after dictating
Control how much Flow changes your words, from raw transcription to a polished rewrite

How it works in Flow

Overview

Auto Cleanup processes your dictation in the background at your chosen level before inserting text. It replaces the previous Smart Formatting feature with more granular control.

Cleanup levels

There are four levels. Medium is the default.

Level	What it does	Example output
None	Transcribes exactly what you said, including mistakes	hey joey, we still on for coffee or? I think we maybe should leave earlier to make it there in time there might um be traffic. What are you thinking?
Light	Cleans up filler words and grammar	Hey Joey, are we still on for coffee? I think we should leave earlier to make it there in time. There might be traffic. What are you thinking?
Medium	Edits for clarity and conciseness	Hey Joey, are we still on for coffee? We should leave earlier; there might be traffic. What do you think?
High	Rewrites for brevity and polish	Hey Joey, are we still on for coffee? Let's leave early to beat traffic. What do you think?

Key behaviors

Runs automatically: Auto Cleanup is applied as part of dictation processing — there's no button to press.
Change notification: When Auto Cleanup makes meaningful changes, Flow briefly shows a "Cleaned up! See what's changed" notification. Click it to see the diff. The notification only appears at Medium or High levels on longer dictations, and never inside AI apps like ChatGPT.
Notification display limit: The notification stops appearing after 5 lifetime displays. The keyboard shortcut and indicator continue to work afterward.
Keyboard shortcut: Press Opt+O on Mac or Win+Alt+O on Windows to review the last cleanup. If Auto Cleanup didn't change anything, the shortcut shows nothing. Pressing the shortcut again while the diff is open closes it.
Undo an edit: Open the three-dot menu next to a recent dictation in the Home tab and select Undo AI edit.
Separate from Transforms: Auto Cleanup and Transforms don't layer. If Transforms are active, Auto Cleanup is suppressed. The two are alternatives, not complements.

Best practices

Start with Medium (the default) and adjust after a few dictations.
Use Light for casual messages where you want your natural voice preserved.
Use High for professional writing where you want concise, polished output.
Use None when you need a raw, word-for-word transcription.

How to set it up

Open the Wispr Flow Hub by clicking the Wispr icon in your menu bar.
Click Style in the left sidebar.
Select the Auto Cleanup tab (the last tab, marked with a "Beta" badge).
Click the level you want. Your selection applies immediately to all future dictations.

Note: If you previously used Smart Formatting, that toggle has moved here. Auto Cleanup replaces Smart Formatting with more granular control.

Examples

Casual message with Light cleanup

You say: "hey joey, we still on for coffee or? I think we maybe should leave earlier to make it there in time there might um be traffic. What are you thinking?"

Flow types: Hey Joey, are we still on for coffee? I think we should leave earlier to make it there in time. There might be traffic. What are you thinking?

Professional message with High cleanup

You say: "hey joey, we still on for coffee or? I think we maybe should leave earlier to make it there in time there might um be traffic. What are you thinking?"

Flow types: Hey Joey, are we still on for coffee? Let's leave early to beat traffic. What do you think?

FAQs

What happened to Smart Formatting?

Smart Formatting has been replaced by Auto Cleanup. If you had Smart Formatting turned on, your setting carries over as Light. If you had it off, your setting is None.

Can I change the level per app or per dictation?

Not yet. The cleanup level applies globally to all dictations.

Does Auto Cleanup change the meaning of what I said?

Auto Cleanup preserves your meaning at every level. Higher levels may rephrase for conciseness, but the intent stays the same. If you're not comfortable with rephrasing, use Light or None.

Can I use Auto Cleanup and Transforms together?

No. The two features are alternatives — when Transforms are active, Auto Cleanup is suppressed.

Limitations and notes

Auto Cleanup is currently in Beta and is actively being improved based on feedback.
The cleanup level applies globally — per-app and per-dictation levels are not yet supported.
This feature is coming soon to Mac and Windows. Mobile support will follow.
The "Cleaned up!" notification appears only at Medium and High levels, and is not shown in AI apps like ChatGPT.
