ニコ生ツリー転送ツール is a Chrome extension that automatically registers videos and quoted videos from NicoNico Douga into the content tree when streaming on NicoNico Live. With this extension, you no longer need to manually navigate to the content tree registration page, even if you end the broadcast midway or pick up requests.

Here's how it works:

1. Open the NicoNico Live broadcast page (and the NicoNico Douga viewing page) and open the pop-up on the broadcast page.

2. Specify the tab where NicoNico Douga is open (or leave it unspecified) and start automatic transfer.

3. The content tree registration page will automatically open in a fixed tab, so all you need to do is play the video on NicoNico Douga.

4. The transfer will end when you close the content tree registration page or the specified tab.

Please note:

• This tool automatically performs content tree registration until submission. If you use it without specifying a tab, it will also respond to NicoNico videos opened in fixed tabs or different windows.
• The automatic transfer of this tool is not linked to the end of the NicoNico Live broadcast slot. Please be sure to manually stop it.
