Is There a Dictation App That Removes Filler Words?

Short answer: Yes. Dictation apps with on-device AI cleanup remove filler words automatically. On Mac, BlaBlaType transcribes your speech locally, then an AI pass drops fillers like "um" and "you know," fixes punctuation and grammar, and delivers polished text into any app. Nothing is uploaded to the cloud.

Why plain dictation keeps your filler words

Classic dictation is literal by design. Its job is to write down exactly what it hears, so every "um," "uh," "sort of" and mid-sentence restart lands in your document. That is fine for a court transcript, but it is exhausting when you are drafting an email or a note. You end up spending as much time deleting fillers as you saved by speaking, which cancels out the main benefit: most people speak around three to four times faster than they type.

The fix is a second step. After the words are captured, an AI cleanup pass reads the raw transcript and rewrites it the way a careful editor would, removing filler, merging false starts, and adding punctuation. Because this rewrite is a separate stage, you can control how light or aggressive it is. If you are weighing dictation to protect your hands from typing strain, the UK's NHS has a useful primer on repetitive strain injury that explains why cutting keystrokes matters.

How AI filler-word removal actually works

Under the hood, filler removal is a small pipeline. Your microphone audio goes to an on-device speech model that turns sound into raw text. That raw text then passes through an on-device AI model that cleans it up. Only the finished, polished text is pasted where your cursor sits. On BlaBlaType, both stages happen on your Mac using Apple Silicon, so there is no server round trip and no upload.

This is powered by on-device AI cleanup built on Apple Intelligence. Beyond dropping fillers, it fixes punctuation and grammar and can adapt tone, so a rambled thought turns into a tidy sentence. If you want to see how automatic punctuation works on its own, we cover it in how to dictate punctuation automatically.

Plain dictation vs AI cleanup

Capability	Plain dictation	AI-cleanup dictation
Removes "um," "uh," "like"	No	Yes
Fixes punctuation automatically	Rarely	Yes
Merges false starts and repeats	No	Yes
Adapts tone (casual or formal)	No	Yes
Runs on-device (private)	Varies	Yes on BlaBlaType
Types into any app	Usually	Yes

The gap is clear: literal dictation captures speech, while AI cleanup shapes it. If privacy is part of your decision, note that not all cleanup is local. Some tools send your transcript to a cloud model. BlaBlaType does not, which matters if you care about whether Mac dictation is actually private.

See it on a real sentence

Here is what the two stages look like on a messy, spoken-aloud thought. The raw transcript keeps everything you said. The cleaned version is what you actually wanted on the page.

• Raw: "So, um, I think we should, like, maybe move the meeting to, uh, Thursday, you know, if that works, I mean, for everyone."
• Cleaned: "I think we should move the meeting to Thursday if that works for everyone."

Same meaning, half the words, and no editing on your part. Because BlaBlaType works system-wide, that cleaned sentence appears directly in your email, your notes app or an AI chat, wherever the cursor is. You can also point it at a custom prompt if you want it to keep a looser, more conversational voice.

When keeping control matters

Removing filler is not always all-or-nothing. Some people want a clean draft; others want to preserve their natural cadence for a personal journal or a podcast script. Aggressive cleanup can also trip over names, product terms or acronyms if you do not guard them. BlaBlaType handles both cases with custom AI prompts and a custom dictionary, so names and jargon are protected and you decide how heavy the edit is.

This flexibility helps specific groups too. People managing attention differences often ramble more when thinking out loud, and clean output lowers the friction of getting ideas down. Organizations like CHADD highlight how reducing that friction supports focus. It also helps multilingual speakers: if you switch languages mid-thought, see whether dictation can handle two languages at once.
