Kokosuki stamp is a Chrome extension developed by ichigo.macaron.dev. It falls under the category of Browsers and is specifically listed under the Add-ons & Tools subcategory. This extension serves as a helpful tool for creating timestamps on YouTube.

The main function of Kokosuki stamp is to assist users in creating timestamps on YouTube videos. It can be used when specifying a specific time in the comments or summary section of a video.

To use Kokosuki stamp, simply click the "+" button, and it will record the elapsed time of the video or streaming at that point. Additionally, you can add notes to the timestamp by writing in the "Enter Memo" field and pressing the plus button. These notes can be edited from the list below the timestamp creation.

It is important to note that in real-time situations, the actual elapsed time may differ due to connection conditions. Furthermore, when using Kokosuki stamp in conjunction with Youtube Live Clock, some display issues may occur, but they do not affect the creation of timestamps.
