The コンテンツツリー登録支援ツール is a Chrome extension that automates the process of registering candidate works in the NicoNico Content Tree. This extension provides a semi-automated solution for creating Content Trees on NicoNico.

With this extension, you can register works not only on the Content Tree registration page but also on the ID list input field on the video posting page. It supports extracting IDs from text files and registering works from browser bookmarks or the nicoExpansion extension.

On the Content Tree registration page, you can register works by extracting IDs from files (only supports text files) or by registering works from browser bookmarks or the nicoExpansion extension.

On the video posting page, you can register parent works while viewing a list with thumbnails and titles. You can also register works from browser bookmarks or the nicoExpansion extension, copy the ID list from the parent works field, and add a menu item to directly navigate to the Content Tree registration page from the video list.

On the Content Tree viewing page, clicking on a thumbnail will take you to the work page, and clicking on "..." will take you to the Content Tree viewing page.

If there are playlists in browser bookmarks or the nicoExpansion extension, you can view the contents of the playlist and use it for registering parent works.

Please note that this extension relies on the specifications of NicoNico's various pages at the time of its creation. If there are any changes made by NicoNico's official side, the extension may not work properly.
