Free, for good

No subscription and no watermark, ever. Your videos stay on your computer while you edit, caption and export.

Before you switch.
The usual questions.

Is Nuzky really free?

Yes. No subscription, no watermark on your videos and no sign-up. Nuzky is open source, so it stays free. If you let AI do the editing, it runs on your own Claude or ChatGPT plan.

When can I download it?

Soon. The first version for Mac, Windows and Linux is on its way. If you have a GitHub account, watch Nuzky's releases and you'll get an email when it's out. Nuzky releases on GitHub

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. CapCut has more templates and effects, and a phone app. Compare Nuzky and CapCut

Are the auto captions free?

Yes, with no limit. Nuzky writes captions from what you say, right on your computer. Pick a style, make the spoken word light up and fix any word it got wrong.

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.

Can AI edit the video for me?

Yes. 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. It runs on your own Claude or ChatGPT plan, and doesn't work on Windows yet.

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 and Shorts?

Yes. Pick the Reels & TikTok export and you get a vertical 1080 × 1920 video with the volume levelled for social apps.
