Split Ninja

TL;DR

It is a local utility tool for basic video trimming and splitting that doesn't force you to upload your files to someone else's server.

Who is this actually for?

Solo content creators and social media managers who need to make quick cuts without the lag of browser-based editors.

The Good

• Runs locally, which is a win for privacy and avoiding bandwidth bottlenecks.
• Focuses on simple tasks like muting and splitting without the bloat of a full NLE.

The Catch (Potential Downsides)

It likely offers zero advanced editing features, so you will still need a real editor for anything complex. There is a high chance this is just a GUI wrapper for FFmpeg that you could run for free in a terminal.
