YouTube video timestamps is a Chrome extension developed by Roman Sadovnikov. It falls under the category of Browsers and specifically the subcategory of Add-ons & Tools. This free extension aims to enhance the YouTube viewing experience by displaying timecodes from video descriptions and comments.

The main feature of YouTube video timestamps is its ability to catch timecodes from the description or comments of a YouTube video and display them conveniently under the video. This allows users to easily navigate to specific sections of a video without having to manually skip through it.

It's important to note that the extension currently only shows the timecodes that have been accessed on the user's computer. This means that if a user has not opened a specific timecode, it will not be displayed by the extension.
