X-Twitter_Youtube Search Helper is a free Chrome add-on developed by シャ・ケー. This tool supports searching Twitter and YouTube, allowing users to input search commands directly from popups.

For Twitter searches, users can easily retrieve page titles, URLs, or both from the current tab, in addition to conducting keyword searches for efficient sharing. The add-on provides a dedicated button for entering search commands and allows for quick command input with the press of a button.

On the YouTube front, users can perform searches with specific filters to find desired content.

Additional features include the ability to copy, clear, post, and perform Twitter searches on selected text, as well as convenient spacing for adding search words. The add-on also ensures radio buttons retain their default positions upon startup.
