FAQ

Common Questions

Everything you need to know about PromptCut's AI silence removal.

How accurate is the AI silence detection?

PromptCut uses advanced audio analysis that differentiates between actual speech and background noise. It's highly optimized for podcasts, lectures, and talking-head videos, ensuring no words are accidentally clipped.

Which media file formats are supported?

We currently support MP4, MOV, WEBM, MP3, and WAV formats. For the best video experience, we recommend using H.264 encoded MP4 files.

Is my data safe and private?

Yes. Media files are processed in isolated, secure containers and encrypted in transit. Your files are automatically deleted from our servers within 48 hours of processing. We never watch or store your content.

Is there a limit on file size?

Yes, limits depend on your plan: Free users can upload up to 50MB, Starter users 300MB, and Pro users up to 2GB per file.

Can I use PromptCut for audio-only podcasts?

Absolutely! While we focus on video, PromptCut works perfectly for audio-only files too. Simply upload your audio, and our AI will strip the dead air just as effectively.
