CowCo is an "everything editor" - a UI to work with your AI. It's a simple utility: fully local, no account, free forever. Your agent is reading and writing files all day. But the moment you want to look at or touch one of those files, you drop out of the flow into a scatter of single-purpose apps. CowCo is your Cowork Companion. Browse a project folder, open and edit almost any file type: text, markdown, documents, spreadsheets, images and more, all in one friendly place.
