How to install Concat, what it needs from your machine, and where to turn when something breaks.
Concat is a video editor that runs entirely on your machine. Download it, open it, drop footage in, cut. No account, no setup. These pages cover the few things worth knowing before and after that.
Install Concat
Every build is a GitHub Releases asset. The download picker hands you the right one; this page covers what happens after.
System requirements
Concat runs everything on your machine, so the hardware sets the ceiling.
Captions, voices and cutout
The AI features run on local models that download once from Settings and then work offline.
Report a problem
Every run writes a log. Settings has the buttons that get it, and your system information, into an issue.
Control Concat from a script
Anything the window can do to a project, a program can do through the API. Here is where that starts.
Building on the API instead? The developer docs cover JSON-RPC, gRPC and MCP.
