Your CapCut drafts open here.
With the cuts, captions and keyframes.
On a Mac or a Windows PC, Nuzky's home screen lists your CapCut drafts. Open one and keep editing where you left off, in an editor that never asks you to upgrade.
Pick a draft on the home screen, or choose New project, then From a CapCut draft
It opens as a Nuzky project, and a list names anything that didn't come over
- What comes over
- Clips, cuts, speed, volume, keyframes, texts, captions and transitions.
- Your draft stays as it was
- Nuzky makes its own project from the draft. Nothing changes in CapCut.
- Then finish with AI
- Press Finish with AI and hand the rest to ChatGPT or Claude. How AI editing works
Two hours of captions and ums.
For every single video.
I make talking-head videos for Instagram and TikTok. Talking is the fun part. Then come two or three hours of writing captions and cutting out every um, every pause and every retake.
CapCut's cheapest paid plan costs 700 CZK a month here in Czechia, about $30. And its Czech captions were so bad that I retyped most of them anyway.
So I'm building the editor I wanted. AI on your computer writes the captions, with the model that knows your language best and the names you actually say. The ChatGPT or Claude you already pay for makes the rough cut. It doesn't make videos for you. It does the boring part.
Nuzky is free, and it stays free. There's no paid plan coming. The code is public, so nobody can take the free version away. Not even me.
Nuzky comes from nůžky, Czech for scissors.

Using ChatGPT plan Manage usage
Every change goes through the same undo as yours. Your controls lock while it works and come back when it stops.
Write to it while it works, attach a screenshot or a video, pick the model, and come back to past chats.
Sign in with ChatGPT inside Nuzky. No terminal, and no credits to buy.
It learns how you edit.
Then cuts the next video your way.
Give Nuzky a few raw recordings and the videos you cut from them, or just your CapCut drafts. It writes down how you edit, with examples from your own videos, and your AI follows it on every new video. Change a line, and the next cut changes with it.

Before you switch.
The usual questions.
Which computers does it run on?
Macs with Apple silicon and macOS 14 or newer. 64-bit Intel or AMD PCs with Linux and glibc 2.39 or newer, like Ubuntu 24.04. Windows 10 or 11 on a 64-bit Intel or AMD PC. Intel Macs, and Windows or Linux on ARM, aren't supported. See the downloads
Can I open my CapCut projects?
Yes, drafts from CapCut on a Mac or a Windows PC. Find them on Nuzky's home screen, or choose New project, then From a CapCut draft. Clips, cuts, speed, volume, keyframes, texts, captions and transitions come over, a list names anything that didn't, and the draft in CapCut stays as it was.
Is Nuzky really free?
Yes. No subscription, no watermark on your videos, no sign-up and no paid plan coming. The code is public, so it stays free. If you let AI do the cutting, it runs on the ChatGPT or Claude plan you already have.
How is Nuzky different from CapCut?
Nothing in Nuzky is locked behind a paid plan, so export never asks you to upgrade. It's made for editing on a computer, and it opens your CapCut drafts. CapCut has more templates and effects, and a phone app. Compare Nuzky and CapCut
Are the auto captions free?
Yes, with no limit. AI on your computer writes them from what you say. Pick the model that's best for your language, give it the names and words you use, and fix anything it still gets wrong. Then pick one of 19 styles or your own, and make the spoken word light up.
Can AI edit the video for me?
Yes, if you want it to. Type what you want, like “cut the ums and pauses and add captions”, and watch it edit in the app. Stop it any time, and one undo takes it all back. Sign in with ChatGPT inside Nuzky to use the plan you already pay for, with no terminal, or connect Claude Code or Codex. Editing, captions and export work without any AI.
How do updates work?
Nuzky tells you when a new version is out. One click downloads it inside the app, and it installs when you restart Nuzky, never by itself.
Are my videos private?
Yes. Your videos stay on your computer, and nothing gets uploaded to edit, caption or export them. If you ask an AI to edit for you, it sees what's said in the video and the frames it checks.
Will videos from my phone work?
Yes. iPhone and Android videos open the right way up, selfies included, and every cut lands on the exact frame you picked.
Is it ready for TikTok, Reels, Shorts and YouTube?
Yes. Pick the Reels & TikTok export and you get a vertical 1080 × 1920 video with the volume levelled for social apps. For YouTube, export widescreen at any size up to 4K.
Who makes Nuzky?
Tomáš Mach, a creator from Czechia who got tired of spending hours on captions and rough cuts. The name comes from nůžky, Czech for scissors.
