# Remove ums, pauses and retakes from a video automatically

> Nuzky turns your recording into text. Then one button cuts the retakes, the filler words and the long pauses, and you edit the rest like a document. It's free, and one undo takes the whole cut back.

Status: early, so expect rough edges. Current version: 0.1.9-alpha. Download it at https://nuzky.app/#download for a Mac with Apple silicon and macOS 15 or newer, a 64-bit Intel or AMD PC with Linux and glibc 2.39 or newer or Windows 10 or 11 on a 64-bit Intel or AMD PC. Intel Macs, and Windows or Linux on ARM, aren't supported. License: GPL-3.0-or-later.

## How it works

1. Transcribe the video. Nuzky writes down every word you say, on your computer. Pauses show as chips with their length.
2. Remove retakes and pauses. One button keeps the last complete take of every sentence you started again, and cuts filler words, hesitations and pauses longer than half a second.
3. Delete what else should go. Select words in the transcript and press Delete. The video cuts with them, and so do the captions.
4. Check it and export. Watch the result. A note says what went and how much time it saved, with Undo. Then export for Reels, TikTok, Shorts or YouTube.

## Good to know

- Cuts the earlier attempts of a sentence you said again, and keeps the last complete one
- Finds filler words in English and Czech, and hesitations like “eee” that the transcript didn't write, in any language
- Long pauses shrink to the length you set, 0.5 s by default
- Two sentences that differ in a number or a “not” both stay
- Every cut keeps a little silence around the words, so no syllable gets clipped
- Captions and overlays stay in sync with every cut

## Questions

### Which languages does it work in?

Retakes, hesitations and pauses are cut in every language Nuzky transcribes. Filler words are looked for in English and Czech, where a word like “um” can't mean something else.

### Can I undo it?

Yes. The whole cleanup is one step, so one undo brings everything back.

### Can AI do the rough cut for me?

Yes. Ask ChatGPT or Claude in Nuzky to cut the ums and pauses and keep the best takes, and watch it edit. It runs on the plan you already pay for. [AI video editing in Nuzky](https://nuzky.app/ai-video-editor.md)
