GOOD TO KNOW
Small questions.
Clear answers.
Is NU AI really free?
Yes. NU AI is free and open source under the MIT license. If you use your own API provider, that provider’s usage charges may apply separately.
Can I use it on Windows or Linux?
The ready-to-install download is currently for Apple Silicon Macs. Windows and Linux packages are planned. Intel Mac users can build the app from source.
Do I have to use AI?
No. Local transcription, pause detection and basic cleanup work without an AI provider. AI review, target-length shortening and translation use your chosen provider.
Are my videos uploaded to a server?
Video and audio files are processed locally. If you enable optional cloud AI features, only transcript text is sent to your chosen provider. You can also use a local model.
How does dubbing work?
Beta dubbing takes a voice reference from the speaker in your video and uses it to speak translated captions while preserving the background. The optional local voice engine requires about a 4.5 GB download. Only clone voices you own or have permission to use.
Can I reject a suggested cut?
Yes. In Review mode you can keep or remove each suggested cut, select words to make your own cuts and preview the result before exporting.
