YouTube Metadata Tools — Tags, Descriptions, Video & Channel IDs

Four fields decide how easy a video is to work with programmatically, and the interface hides all four. Tags are still stored in the page data though the editor no longer shows them. Descriptions are collapsed behind “...more” even when they hold the timestamps and sources you need. The video ID is buried in whichever URL shape you happen to have, and the channel ID sits behind a handle that its owner can change at any time. These tools pull each one out as plain, copyable text — no API key, no login.
