A Chinese woman who fixes her neighbors' broken machinery, often farming equipment. Her workshop is an open mostly-outdoor space, so her videos' sound are the sounds of various tools with a background of nature. Here's one of her shorter videos (a lathe repair, appropriately enough) to give you a good idea of her typical video style.

Townsends. Whole vibe of a white guy larping as an 18th century colonist gives some kind of iffy vibes but beyond that I absolutely adore the channel

Jacob Geller

I'm not totally sure I understand the definition of cozy but noted streamer Nor Thernlion makes the only good content on youtube/twitch

if you like pokemon, there's a guy called jrose11 that's been systematically seeing which gen 1 pokemon can solo the game the fastest. there's a pretty large backlog at this point, and the strategies get pretty inventive at points.

Technology connections is just some nerd talking about old technology and it's super chill.

There's a channel of a family that live in the countryside in Azerbaijan. It's just farming and cooking - no talking at all. Pure bliss.

LGR. vintage computers, technology and gaming with smooth jazz in the background. just makes me happy.

i like the Dead Meat Killcount, its the only way i can really watch horror movies. Having gruesome murders explained by a excited dude making silly jokes is actually way more comforting than it should be

Jago Hazzard is my go-to for London railway history. A fun watch, if a tad dull at times, with a plucky narrator.

There are a bunch but off the top of my head Oceanliner Designs makes great, well produced, videos on ships. Very cozy even when talking about shipwrecks

Jomboy if you love random silly sports breakdowns. Very short form, great even if you don't watch sports

Marcus of Cosmonaut Variety Hour. Generally just slop reviews but funny and super rewatchable. I think I've watched his Blade trilogy review like 5 times

not really a youtuber but i fall asleep to Jerma VODs every night lol

martijn doolard is a dutch bloke renovating a pair of stone cabins in the italian alps. gorgeous scenery and so relaxing

Hazel! Her videos are just "let me talk 1 hour about a very specific obsession in old anime/ video games", it's great

SulMatul. She does in depth game videos that are a combination of playthrough retrospective, when I'm done binging one I feel like I've both played the game and talked with someone for hours about it.

Daniel Naroditsky. For some reason I love to watch chess while eating, and he's my favorite chess streamer.

Posy. Videos with an art, technology, and science bent but you never really know what to expect other than the vibes being immaculate.

Shortcat is nice, I like Gecko as well for Mario Kart videos.

Soursweet - kind and wholesome YouTuber with a soothing voice. Surprising combo of entertaining and cozy vibes watching his edited sessions of playing DayZ, a PvP zombie survival shooter.

ProcessX - Japanese YouTube channel that's shows manufacturing and crafting processes. No talking but English subtitles are available. Lots of satisfying manufacturing noises with soft classical music in the background.

This advertisement is paid by Gholdengo (TM), do not ban Gholdengo (TM) from SV OU, Gholdengo (TM) is totally fair and balanced.

Jimothy is cool. I also love small-mid-size niche youtubers, I like Aegon of Astora, for a rambly, leftist academic analysis/let's play of Souls game. Infinite Cringe for Dragons Dogma and Yuri VN commentary. Alt Schift/Schwift X/Glidus for their Song of Ice and Fire analysis and ASOIAF conspiracy iceberg discussions, One Piece Podcast, and the nichest of the all, Moosebones for running Monster Rancher 2 PVP competitive tournaments.

18th Century Cooking by Townsends Delicious looking and occasionally strange recipes from the 1700s colonial America.

Food Wishes Delicious looking modern food made by a chef with a very odd speaking cadence.

Thomas Johnson Antique Furniture Restoration - really fascinating restoration of wooden antiques with a cozy presenter.
