How to automatically download YouTube videos

I am looking for a program that can automatically grab all YouTube URLs directly from my clipboard. Ideally, the moment I copy a link while browsing YouTube, it should instantly add it to a download queue. Doing this manually via copy and paste is incredibly tedious.
I have already tested several options: Youtube downloader hd, free youtube downloader, freemake video converter among others, but none of them offer this specific automation.
Does anyone know of a tool that actually does this?

jdownloader

The latest update for Firefox YouTube video downloader handles everything automatically—if that’s what you’re into. It pulls from YouTube or just about any site where it "detects" a video clip, so there's no need to bother typing in some long, tedious URL.

It offers a whole suite of direct download options, automatic conversion into whatever format you prefer, and a bunch of other useful little perks.

Ant toolbar

This downloader actually lets you grab videos in batches: http://www.videoconverterfactory.com...ube-video.html
But yeah, you still have to deal with the whole copy-paste URL dance.
Honestly, I can't seem to find any tool lately that just... automatically pulls the videos for you. If anyone knows a legit program that does that, please, let me know! I am seriously getting so tired of using these tools mentioned above. Thanks in advance!

Look, just try this out: FlvtoConverter. You can grab it here (just click or download FlvtoConverter.exe—you're getting the actual software, not some Windows 10 patch or a Chrome extension)
.
How does it work? It’s simple. You just paste the YouTube URL, a little window pops up, and you hit MP3. One less thing to copy and paste, if that even matters. If you've got an entire playlist, just grab the playlist link and it starts ripping the whole thing in whatever format you want. You can even pick between HD or standard quality. Give it a shot 😉
