How to Remove Filler Words and Dead Air from Talking-Head Videos on Mac (2026)
The apps that automatically remove filler words and dead air from talking-head video on Mac in 2026 — Descript, Gling, Premiere Pro, CapCut, auto-editor, and BlitzCut compared on accuracy, speed, and price.
Six tools remove filler words and dead air from talking-head video on Mac in 2026: Descript, Gling, Premiere Pro, CapCut Pro, auto-editor, and BlitzCut. Descript and Gling upload your footage and meter your minutes. Premiere Pro needs a $22.99/month Creative Cloud seat. auto-editor is free but runs in Terminal. BlitzCut does both jobs for $16.99/month, partly on-device — silence removal is local, transcription runs in the cloud without uploading your video. Accuracy on filler words is roughly comparable across all of them; the differences that matter are where the processing happens and how long the round trip takes.
Two Different Problems
People say "remove filler words" and mean one of two things, and most tools are better at one than the other.
Dead air is silence — the pause while you find the next sentence, the gap where you took a sip of water. Detection here is an audio problem. A tool looks at the waveform, finds anything below a threshold for longer than a set duration, and cuts it. This is mechanical and every tool on this list does it well.
Filler words are "um," "uh," "like," "you know," "so" at the start of a sentence. Detection here is a transcription problem. The tool has to transcribe your speech, identify the filler tokens, and map them back to timecodes. Accuracy depends entirely on how good the transcription is, which is why accents and background noise wreck it.
A tool that cuts silence perfectly may leave every "um" in place. Check which one you're buying.

Checked August 2026. Round-trip times are for a 30-minute 1080p recording on an M-series Mac, including review.
Descript
The default answer, and a good one if you're already in it.
Descript transcribes your recording, then gives you two switches: Remove Filler Words and Shorten Gaps. Filler word removal is a checkbox that strips detected "um"s and "uh"s across the whole transcript at once. Shorten Gaps doesn't delete silence outright — it compresses any gap over a threshold down to a target length, which sounds more natural than hard cuts.
That gap-shortening behavior is genuinely better than a straight silence cut, and it's the feature I'd miss most switching away.
The costs: $24/month on Hobbyist annual or $35/month on Creator, per seat, and Creator caps at 30 media hours a month. Every re-upload burns hours. And everything goes to Descript's servers first, which for a 30-minute 4K recording is a real wait before you've made a single edit.
Gling
Gling is built specifically for YouTubers and it's the closest thing to a purpose-built version of this job.
It removes silences, filler words, and — the part nobody else does — bad takes. You flub a line, say "let me try that again," and start over. Gling detects the retake and cuts the flubbed one. For anyone who records in long unscripted sessions, that's the feature worth paying for.
It also generates titles, descriptions, and subtitles, and exports an XML timeline to Premiere, Final Cut Pro, or Resolve if you want to finish elsewhere.
Pricing is metered by minutes, running roughly $15–$30/month depending on tier, with a limited free allowance to test it. Like Descript, it's cloud-based: upload, wait in the queue, download.

Adobe Premiere Pro
If you already pay for Creative Cloud, this is free to you and it's good.
Premiere's Text-Based Editing transcribes the clip and shows the transcript in a panel. Filler word detection highlights every "um" and "uh," and you can delete them all in one action. Transcription runs locally on your machine.
What it doesn't do well is dead air. There's no one-button silence removal — you're deleting gaps from the transcript or the timeline yourself. For a 30-minute unscripted recording that's still a lot of clicking.
$22.99/month for the single app, which is hard to justify for this feature alone.
CapCut Pro
CapCut has both Remove Silence and Remove Filler Words under its AI Tools menu, and both need CapCut Pro at $19.99/month or $179.99/year.
They work. The issue is the shape of the workflow: the features are three or four menus deep in a general-purpose editor, cuts land in the timeline with no dedicated review interface, and accuracy drops noticeably with background noise or music. We timed a 5-minute video at 8–12 minutes end to end in does CapCut remove silence automatically.
auto-editor
Free, open source, and the fastest option on this list if you're comfortable in a terminal.
pip install auto-editor
auto-editor input.mp4 --margin 0.2s
It analyzes the audio waveform, cuts anything below the threshold, and writes a new file. It's fast, it's local, and it has no limits of any kind.
It does not remove filler words. auto-editor works on audio levels, not transcription, so "um" said at normal volume is just speech to it. It also has no review step — you get the output file and check it yourself.

BlitzCut
BlitzCut removes silence on your Mac and flags filler words from a cloud-generated transcript. No video upload, no queue, no metered minutes.
Import the recording, silence removal runs automatically on-device, and you get the transcript as the editing surface — delete a word, the video cuts. Filler words are flagged in the transcript for removal. Then captions, then export up to 4K.
$16.99/month, $69.99/year, or $6.99/week, with a 3-day trial. One subscription covers Mac, iPhone, and iPad.
Because processing is local, a 30-minute recording is roughly two minutes end to end, and it works with no connection at all.
What BlitzCut doesn't do: bad-take detection like Gling, gap-shortening like Descript's Shorten Gaps, or anything resembling color grading. It's a narrow tool.
Which One
Already paying for Creative Cloud: use Premiere's Text-Based Editing. You own it.
Long unscripted YouTube recordings with lots of retakes: Gling. Bad-take detection is worth the upload wait.
Team workflow, voice cloning, shared editing: Descript, and watch the 30-hour cap.
Comfortable in Terminal and only need silence gone: auto-editor, free.
Recording talking-head video weekly and want it done in two minutes without uploading: BlitzCut, $16.99/month with a 3-day trial.
Frequently Asked Questions
What app automatically removes filler words from video? Descript, Gling, Adobe Premiere Pro, CapCut Pro, and BlitzCut all detect and remove filler words using transcription. auto-editor removes silence only — it works on audio levels and can't identify spoken filler words.
Can I remove filler words for free? auto-editor is free and open source but only removes silence. CapCut's free tier includes auto-captions but locks filler word removal behind Pro. DaVinci Resolve's free version can do transcript-based deletion manually.
Does Descript remove filler words automatically? Yes. Descript has a Remove Filler Words toggle that strips detected filler tokens across the whole transcript, plus a separate Shorten Gaps feature that compresses silences rather than cutting them entirely.
What does Gling do that other tools don't? Bad-take detection. Gling identifies when you restarted a sentence or flubbed a line and cuts the failed attempt, which is specific to long unscripted recording sessions.
How accurate is automatic filler word removal? Good on clear single-speaker audio in a quiet room. Accuracy drops with background noise, music, multiple speakers, and non-native accents, because the feature depends on transcription quality. Always review before exporting.
Which filler word remover works offline? auto-editor runs entirely on your Mac. BlitzCut's silence removal is offline; its transcription needs a connection. Premiere Pro transcribes locally. Descript, Gling, and CapCut's AI tools all require a connection.
