Why Local-First?
Your videos should not need to leave your computer before you can start creating.
Save Time and Data
Avoid lengthy uploads and unnecessary bandwidth usage before processing can begin.
Built for Unreliable Connections

Your Files Stay With You
Source videos, transcripts, analysis results, and generated clips remain on your machine unless you explicitly use an external provider or Arena Cloud.
Ready for Local AI Models
Arena's local-first architecture creates a path toward optional local transcription, analysis, and embedding models in the future.
