This project is a browser extension for Chrome and other Chromium based browsers that organizes YouTube subscriptions. If someone follows a lot of channels on YouTube, the default subscription list can become a long, unsorted mess. This extension lets a person sort those channels into custom categories, and it shows those categories right inside YouTube's own sidebar so it feels like a native part of the site rather than a separate tool. After installing it, a user can sync their current subscription list with one click, then create as many categories as they want, each with its own name, color, and icon. On any video page or channel page, a new "add to category" button appears next to the subscribe button, so a channel can be sorted the moment someone notices it. There is also a management panel for selecting multiple channels at once, dragging them between categories, and searching across every category by keyword. Each YouTube account gets its own separate set of categories stored on the same browser, so switching accounts does not mix up the organization. Categories can be exported to a CSV spreadsheet file, which can be opened directly in Excel, and that same file format can be used to import categories back in bulk. All of the data stays on the user's own computer in the browser's local storage. The extension has no backend server, does not collect subscription data, and does not send any account information anywhere outside of YouTube's own pages. Most people can install a ready-built version from the project's releases page without needing any development tools, though the source code can also be built manually with Node.js for those who want to.
